Furthermore, the parasite was shown to be genetically most closely related to European rather than North American strains (10). 1 2 3 This zoonosis is characterised by long term growth of metacestode (hydatid) cysts in humans and mammalian intermediate hosts. Sonography of right kidney showed the normal dimension of 121 mm and parenchyma thickness of 23 mm, without any stone or obstruction but in left kidney with a dimension of 165 mm and parenchyma thickness of 18 mm, one typical cyst with a dimension of 120 93 mm was seen. CVJ. At both locations, the dog lived in a rural setting and had the freedom to roam on the properties, with potential exposure to foxes, coyotes, and rodents. Histopathology of the intraoperative biopsies demonstrated the presence of multi-loculated cystic structures containing eosinophilic, fragmented, hyaline membranes that stained with Periodic acid-Schiff (PAS), necrotic debris, mineralized granular material, and prominent chronic eosinophilic and granulomatous inflammation (Figure 2 A,B). Echinococcosis (Say this: eh-kinno-cock-ko-sus. CE is caused by cyst-like tapeworm larvae growing in the body. Nunca permitimos a poltica partidria como base para checagem. However, hepatic alveolar echinococcosis behaves like a malignant tumor and can have a prolonged incubation period prior to onset of clinical symptoms; in humans this is typically 5 to 15 y (3). The two most important forms, which are of medical and public health relevance in humans, are cystic echinococcosis (CE) and alveolar echinococcosis (AE). The site is secure. Children are particularly at risk because of their close contact with pets and possibly less attention to hygiene. Lhistologie, limmunohistochimie et lamplification en chane par la polymrase ont confirm Echinococcus multilocularis comme la cause de la masse hpatique. It appears that the separation of wildlife and domestic animal strains is breaking down and that a single strain may be emerging. NADIS. For kidney hydatid cysts, PAIR (puncture- aspiration- injection- re-aspiration) is a successful method of therapy, although when the cysts are larger than 6 cm, embedding the subcutaneous tube and evacuating the contents of the cyst are needed several times to decrease the risk of infection because the fluid of hydatid cyst is containing protoscolex. Infection with this parasite is harder to diagnose than Dipylidium because the segments are small and not readily seen. In order to leave comments, you need to log in. Careers, Unable to load your collection due to an error. The other common tapeworms that can infect a dog are members of a group called Taenia. After the tapeworm egg is eaten, it can grow into a large cyst, usually in the liver. In most cases, hydatid disease takes years for the first symptoms to appear and when they do occur they are usually related to where the parasite is present in the body, most often in the lung and liver. To the best of the authors knowledge, only 1 case has previously been diagnosed: in British Columbia (6). Worming with praziquantel every four weeks will also prevent. Dogs and wild canines eat cysts of cervid lungs and liver, and worms mature. NADIS hopes that you have found the information in the article useful. Treat dogs regularly (at least every six weeks) with a wormer which contains the active ingredient praziquantel. Eckert J, Deplazes P. Biological, epidemiological, and clinical aspects of echinococcosis, a zoonosis of increasing concern. Give your dogs routine worming treatments to remove tapeworms. The disease is found all over the world where humans are in close contact with dogs and livestock. Tapeworms are not readily diagnosed with routine fecal examinations. The treatment is done with the aim of eliminating the parasites from the person's body and eliminating the parasite's cysts, and the doctor usually recommends the use of antiparasitic drugs, such as Mebendazole, Albendazole and Praziquantel, as they work favoring the elimination of the parasite. Alveolar hydatid disease. It is caused by the transmission of an abnormal protein called a prion. Harandi M, Moazezi S, Saba M, Grimm F, Kamyabi H, Sheikhzadeh F, et al..

Disease information and advice Hydatid disease (echinococcosis) Hydatid disease (echinococcosis) Key messages Hydatid disease occurs worldwide and is mainly associated with sheep farming. The cysts keep growing, which leads to symptoms. Hydatid disease is caused by the formation of cysts following ingestion of Echinococcus granulosus eggs. This cystic stage causes a disease known as hydatidosis or echinococcosis, for which there is no simple treatment. In the life cycle of this parasite, dogs are the main hosts of Echinococcus mature worm, also vegetarians are considered as intermediate host of this parasite, so the humans may be intermediate host by swallowing eggs containing larva of Echinococcus granulosus due to touching dogs or consumption of contaminated vegetables and water. This constitutes the first description of endemic E. multilocularis in Ontario. All Rights Reserved. Echinococcosis is a zoonotic disease and created by the larva of Echinococcus granulosus parasite. While a variety of products are available to treat tapeworms in dogs, they are not all equally effective. First, a tapeworm egg must be ingested by a flea larva, an immature stage of the flea. . Peregrine AS, Jenkins EJ, Barnes B, et al. Mule deer herd Chronic wasting disease (CWD) is a contagious and fatal neurological disease found in deer, elk, and moose. However, the presence of the parasite can be identified through routine tests such as X-rays, CT scans or ultrasounds, as the parasite forms cysts that can remain lodged in various organs. As the flea is digested within the dogs intestine, the tapeworm egg is released, hatches, and then anchors itself to the intestinal lining, therefore completing the lifecycle. The prevention of infection by Echinococcus granulosus can be done through simple measures such as: In addition, it is important to avoid consuming raw vegetables from unknown sources, and when ingesting, make sure they have been properly sanitized, in addition to washing your hands whenever you come into contact with animals and before preparing food. 122, Postfach 8466, Ch-3001, Bern, Switzerland (Gottstein). The definitive host of Echinococcus granulosus it is the dog, that is, it is in the dog that the adult worm develops, whose eggs are released into the environment through feces, contaminating food, childrens hands and pastures, for example. With today's deworming medications, treatment is simple and effective. Right lateral abdominal radiography revealed loss of serosal detail throughout the abdomen. Hydatidose alvolaire hpatique The origin of the case described here is unclear, as only formalin-fixed tissues were available and genotyping PCR analysis, as described in Jenkins et al (10), was not successful. The translator user relied on the following text: Tapeworms are flat, segmented intestinal parasites of the cat and dog. Since tapeworm medication is so effective, recurrent tapeworm infections are almost always due to reinfection from fleas and not the failure of the deworming product. Set up your myVCA account today. Dogs are the primary hosts of Echinococcus granulosus and shed eggs in their faeces; sheep and other livestock become infected by grazing pasture that has been contaminated with dog faeces. We never allow partisan politics as information. Hydatid disease is defined by the existence of hydatid cyst in human which may be without any symptoms for a long time . Flea control involves treating the dog and the environment (for more information, see the handout Flea Control in Dogs). A 2-year-old boxer dog from southern Ontario was evaluated because of acute onset lethargy. After diagnosis of pathologist, the patient received Albendazole 10 mg/kg daily for 12 weeks. The symptoms of hydatid disease may vary according to where the hydatid cyst is formed, and there may be different symptoms, the main ones being: In addition, when the hydatid cyst ruptures, other complications can arise that can be life-threatening, such as pulmonary edema and anaphylactic shock, which is a type of severe allergic reaction. The infection is caused by oral-fecal route and transferred by parasite eggs, mostly due to consuming infected vegetables and food by stool of dog containing the parasite egg. Tua Saude Website REF93782 Verified. Echinococcosis. The vast majority of infestations in humans are caused by E. granulosus. The parasite develops slowly, which means that the disease can remain asymptomatic for several years, making diagnosis difficult. The parasite develops slowly, which means that the disease can remain asymptomatic for several years, making diagnosis difficult. Copyright 2002 by the American Academy of Family Physicians. According to the pressure on hydatid cyst, getting torn and the release of hydatid liquid containing protoscolex during the surgery are not unusual, and this issue is the most important cause of invasion in this disease, therefore applying scolicidals during the surgery is necessary. (Fig.2).2). Tapeworms must first pass through the flea (the intermediate host) before they can infect the dog. Renal hydatid cysts may be silent for years and do not show any obvious symptoms. Please disable your AdBlock in order to access free content. Combination of diagnostic methods is necessary for diagnosis of hydatid cyst in some organs with no symptoms, like kidney, such as clinical history, serological analysis, urine analysis and medical imaging that finally confirmed the disease by showing hydatid cyst,layers of hydatid cyst or protoscolex.For treatment of these cases both pharmacotherapy and surgery are needed. The https:// ensures that you are connecting to the Inclusion in an NLM database does not imply endorsement of, or agreement with, Dogs used for hunting feral pigs have a relatively high rate of infection, especially in the bushlands around Perth. Intermediate hosts are usually herbivores, especially sheep, but omnivores such as pigs and humans can also be infected. However, until the source of the infection in the dog described here is determined it would be premature to comment on whether preventative treatment of dogs with praziquantel is required in parts of Ontario; research is required to determine the distribution of E. multilocularis in Ontario. Larvae of the parasite in intermediate hosts is capable to creae cysts in all body organs. Key Points. Photograph of liver. Rahmati K, Maghsoud AH, Matini M, Haghi MM, Fallah N, Fallah M.

Baby Feeding - From zero to 36 months;133, ADHD (attention deficit hyperactivity disorder);222. The symptoms are seen when the cyst is enlarged in the involved organs and also is identified accidentally in operation and paraclinical tests such as pathologic imaging or performing serologic tests. Figure 3: Removal of fallen stock as quickly as possible will minimise access by scavenging dogs. In most cases, hydatid disease takes years for the first symptoms to appear and when they do occur they are usually related to where the parasite is present in the body . In the United States, echinococcosis is mostly found in the Southwest and Alaska. 8600 Rockville Pike Hydatid disease is defined by the existence of hydatid cyst in human which may be without any symptoms for a long time [6]. In this case report, the patient had a hydatid cyst in kidney for years, and because it did not show specific symptoms, it was silent and progressive. Scooting can also occur for other reasons such as impacted anal sacs. Thereafter, alveolar hydatid cysts typically develop within the liver. Less commonly, segments are seen moving around the dogs anus. Histology, immunohistochemistry, and polymerase chain reaction confirmed Echinococcus multilocularis as the cause of the hepatic mass. Fence in your garden to keep out pets and wild animals. At the time of the laparotomy, blood was actively filling the abdomen; exploration identified the liver as the source of hemorrhage. Under hot, dry summer conditions they may only last three weeks. Afterwards, the patient was followed up monthly for 1 year, and no recurrence was observed. How Is Hydatid Cyst Diagnosed?

In addition, contamination can happen through the consumption of contaminated food and water, allowing eggs to enter the body, transforming into an oncosphere in the stomach, affecting blood and lymphatic circulation and then reaching the liver, for example. A few cases of tapeworm infection have been reported in children. The eggs can remain viable in the soil for several months or years and are normally consumed by pigs, cattle, goats or sheep, where hydatid cysts develop in the liver and lungs, which can be consumed by dogs, especially in places where animals are raised for slaughter. In humans, the disease is called hydatidosis, hydatid disease, or hydatid cyst disease, and results in cysts being formed in the liver. It can also be acquired from dogs and dingoes. Although there is treatment with antiparasitic drugs, some cases need to be treated with surgery to remove the parasites that are growing in the body and, therefore, the best way to eliminate the disease is to prevent infection with simple measures such as deworming all domestic dogs, washing hands before eating and preparing food correctly. Several types of tapeworms are known to infect pets, but the most common species observed in dogs is Dipylidium caninum. Occasionally, they can be seen moving on the hairs around the anus, or more commonly, on the surface of freshly passed feces. Result of ultrasound and CT were showed a simple cyst for R/O cancer and without any clear diagnosis, cystectomy was scheduled for the patient, and the specimen was sent to the pathology department. These findings are consistent with the metacestode stage of Echinococcus multilocularis. However, the dog described here had only lived in southern Ontario and Manitoulin Island, Ontario, and therefore must have become infected in one of these 2 locations. The reaction of parasites against the immunity system is too complex and has been vague yet. The cysts are often found on x-rays. Hydatid disease is a parasitic infection caused by a tapeworm's eggs. Use of this article is limited to a single copy for personal study. The infection is called cystic echinococcosis (CE). Other symptoms include itching, coughing, bloody stools, chest pain, and fever.

When the embryonic membrane gets torn, firstly larva enters the abdominal area through penetrating the intestinal walls, then gets into the intermediate portal vein system or lymphatic system and reaches to different organs. Arrows denote edge of liver lesion. The masses were cystic and had extensively infiltrated liver tissue. Because the cysts are usually slow growing, infection in people may go unnoticed for years. Flea control is critical in the management and prevention of tapeworm infection. Copyright 2023 American Academy of Family Physicians. Dogs acquire Taenia infections by eating an infected host. However, either route would be novel in Ontario. Photomicrographs of a section of cystic tissue from the mass shown in Figure 1B. In June 2012, a 2-year-old 22-kg neutered male boxer dog was presented to a small animal clinic in southern Ontario with a 12-hour history of inappetance and lethargy. Thereafter, alveolar hydatid cysts typically develop within the liver. These cysts can also grow in the lungs, brain, and other organs. The second region comprises the southern parts of Alberta, Saskatchewan, and Manitoba and 13 adjacent USA states (5). Eggs can survive freezing for a year and remain infective for six months in cool moist conditions such as on pasture. How Is Hydatid Cyst Transmitted? Hydatid cyst can be made in liver, lung and rarely in heart, breast, thyroid, soft tissue of neck and kidney.

Read the article below to know more about them. Treatment. As with the more common tapeworm, Dipylidium, human infection with Echinococcus is rare, yet possible. During grooming, or in response to a flea bite, the dog inadvertently swallows the flea. They belong to a different family (cestode) than other intestinal parasites, such as hookworms and roundworms, which are other common intestinal parasites of cats and dogs. In some areas, domestic dogs, and to a lesser extent cats, may also act as definitive hosts, i.e., following consumption of infected rodents . But humans can get the disease if they accidentally eat or drink anything infected with the parasite. Muni S, Kumari N, Pankaj D, Kumar A, Pintu DK. Sequence data from a PCR-generated fragment of the mitochondrial 12S rRNA gene (1), and restriction fragment length polymorphism analysis of PCR-generated fragments from the mitochondrial 12S rRNA and NADH dehydrogenase 1 genes (2) confirmed the identity of the metacestode as E. multilocularis. Renal hydatid cyst is the third rank (24%) which is a rare and important disease. The definitive host of Echinococcus granulosus is the dog, that is, it is in the dog that the adult worm develops, whose eggs are released into the environment through feces, contaminating food, children's hands and pastures, for example. chez un chien Boxer du Sud de lOntario. government site. We never allow medication recommendations, medication package inserts or any medication guidance. In addition, contamination can happen through the consumption of contaminated food and water, allowing eggs to enter the body, transforming into an oncosphere in the stomach, affecting blood and lymphatic circulation and then reaching the liver, for example.

Disease is seen rarely throughout the UK, however certain areas such as Wales and Western Scotland have a significantly higher number of cases than elsewhere, probably due to the large number of sheep and the extensive farming systems in these areas. A person must swallow an infected flea to become infected with this type of tapeworm. The eggs are splitted in the intestinal duct; the larva enters to the blood through the intestinal mucosa. In most cases, hydatid disease takes years for the first symptoms to appear and when they do occur they are usually related to where the parasite is present in the body, most often in the lung and liver. The analysis of blood and biochemistry factors was normal, but in urine analysis, a little mucus, epithelial cell and a high amount of RBC were seen and then sonography of kidneys was prescribed for the patient. and transmitted securely. Read the full fact sheet Contact with dog faeces infected with tapeworm eggs may cause hydatid disease, which is when cysts form in vital organs such as the liver. Careers, Unable to load your collection due to an error. Infection is transferred through the oral-fecal pathway by eggs of the parasite and more by eating vegetables and food contaminated with dog stool containing eggs of the parasite. In some cases, surgical removal of the cyst may also be indicated, especially when it is very bulky and is present in an easily accessible location. As the proglottid dries, it becomes a golden color and eventually breaks open, releasing the fertilized eggs into the environment. After the surgery, the patient was discharged from the hospital without any symptoms. Moreover, scolicidal must be taken before the surgery to decrease the risk of infection. Occasionally, dogs will drag their bottoms on the ground, a behavior known as scooting, in order to calm irritation associated with the proglottids. ), also called hydatid disease, is an infection caused by eating food or water that is contaminated with the eggs of the Echinococcus worm. Do not feed offal to dogs or allow them access to animal carcasses. They usually have a single primary host species, although may use other species to complete their life cycles. What are the symptoms of cystic echinococcosis (CE)? Treatment for this disease is based on where the cysts are found and what problems they are causing. Always wash your hands after handling your pets. Surveys in regions with a high incidence of human cases consistently reveal a high prevalence of infection in wild dogs, kangaroos and wallabiesand feral pigs. This disease is more frequent in children due to direct contact with dogs, for example, because the eggs can be adhered to the fur. In summary, it is important that veterinary practitioners recognize that dogs can act as intermediate and definitive hosts for E. multilocularis, and that dogs with intestinal infections pose a serious zoonotic threat. Echinococcosis is infection with larvae of the tapeworm Echinococcus granulosus (cystic echinococcosis, hydatid disease) or Echinococcus multilocularis (alveolar disease). Hydatid disease is an infectious disease caused by the parasite Echinococcus granulosus which can be transmitted to humans through the ingestion of water or food contaminated with the feces of a dog infected by the parasite. Signup to our newsletter for regular updates.

B Note degenerating cysts in the liver that are lined by a hyaline membrane (laminated layer; arrows). This silence causes irreparable damage to the involved organs, and unfortunately, the patient may lose the involved organ. Echinococcus multilocularis is a cestode capable of causing potentially fatal zoonotic disease (3). This is especially relevant for farmers in contact with farm dogs as they are at higher risk of carrying the tapeworms. Liver (5070%) and lungs (2030%) are mostly involved organs in hydatid cyst, but it is rarely seen in other organs like heart, breast, thyroid, the soft tissue of neck and kidney [5]. Echinococcus granulosuss larva can tolerate against anti-parasite responses of host by creation of laminated layer, versus, host can prevent from hydatid cyst development by creation of fibrotic layer around it. Federal government websites often end in .gov or .mil. Four species are recognised and belong to the family Taeniidae. Correspondence address. Anyone interested in obtaining reprints should contact the CVMA office (gro.vmca-amvc@nothguorbh) for additional copies or permission to use this material elsewhere. When secondary or dead-end hosts ingest tapeworm eggs, the newly-hatched tapeworms migrate out of the intestines into the bloodstream and are deposited in various organs around the body, where they form cysts. Human hydatid disease occurs after infection with Echinococcus granulosus, mainly involves liver and lung, while hydatid involves heart is infrequent. Figure 1: Echinococcus granulosus tapeworms live in the intestines of dogs, shedding infective eggs which are passed out in faeces. Also, the eggs passed in the faeces are too small to be seen without special filtering and magnification. A liver cyst may cause no symptoms for many years, until the cyst is large enough to cause problems. Mueller N, Frei E, Nunez S, Gottstein B. The parasiticide may be given either in the form of tablets or by injection. Hydatid disease, also known as echinococcosis, or cystic hydatid disease, is caused by an infection with the larvae of the tapeworm Echinococcus granulosus. No protoscolices were observed in the tissue sections examined. Hydatid cyst is one of the most important zoonotic diseases that is caused by Echinococcus granulosus. The best method of therapy is surgery and removing the hydatid cyst of the kidney without getting torn, and it depends upon the status and size of the cyst. Hydatid cyst is one of the most important zoonotic diseases made by Cestoda Echinococcus, especially Echinococcus granulosus. However, data from Europe indicate that this clinical presentation occurs in dogs either as a result of ingestion of a large number of eggs from the environment, or as a result of an intestinal infection with the adult tapeworm (i.e., subsequent to ingestion of an infected rodent) and release of eggs into the intestinal lumen (7). You may also need medicine to keep the tapeworm from coming back. The cranial abdomen was tense and painful on palpation. Since the owners of the dog described here indicated that the dog would eat just about anything, either route of infection is a possibility for this case. (Fig.1).1). Human echinococcosis (hydatidosis, or hydatid disease) is caused by the larval stages of cestodes (tapeworms) of the genus Echinococcus. Although infection in humans is rare, it can be serious. Thus, the symptoms that are usually related to hydatid disease are shortness of breath, frequent nausea, belly swelling or excessive tiredness. Animals such as cats and dogs may get infected when they eat Echinococcus larvae in infected rodents and mice. By Already have a myVCA account? Echinococcosis (Say this: eh-kinno-cock-ko-sus. Also, the eggs passed in the faeces are too small to be seen without special filtering and magnification. When eggs of Echinococcus are passed in the feces of the dog, humans are at risk for infection. In this way, it is possible to avoid the rupture of the cyst and the emergence of complications. "Another, less common, group of tapeworms called Echinococcus is of increasing concern as a threat to human health.". Malcolm Weir, DVM, MSc, MPH; Ernest Ward, DVM; Updated by Amy Panning, DVM. In this way, it is possible to avoid the rupture of the cyst and the emergence of complications. Signs and Symptoms: The time from ingestion of the eggs to developing symptoms of hydatid disease can range from months to many years.

The tapeworm occurs in dogs and occasionally in other carnivores, including dingoes, foxes and cats. All rights reserved, the state of North Dakota. Before Computed tomography scan illustrated the cyst in details (Fig. These tapeworms cause serious, potentially fatal disease when humans become infected. Hepatic alveolar echinococcosis in dogs is an extremely rare diagnosis in North America. Exploratory laparotomy revealed a hemorrhagic, destructive, liver mass. Once ingested, the eggs can develop into cysts.They can also be carried by flies, beetles, footwear, clothing, wind and water. A Multifocal, tan-colored, multinodular masses in the liver. The final hosts of the parasite are dogs and Canidae and the intermediate hosts are the livestock such as cows, sheep and goats. In Australia most cases are recorded from sheep growing areas with Western Australia second to New South Wales. Humans can get echinococcosis by eating food or drinking water contaminated with feces from infected dogs. FOIA It is strongly recommended that all details andinformationpublished be carefully verified. Echinococcus multilocularis was previously not known to occur in Ontario. Overview What is hydatid disease? As a result, formalin-fixed tissue was sent for polymerase chain reaction (PCR) testing at the Institut fr Parasitologie, University of Bern, Switzerland. Results showed the definitive diagnosis of hydatid cyst and the protoscoleces were seen in tissue section (Fig. Now test your knowledge by enrolling and trying the quiz. When segments of the tapeworm break off and pass into the dogs stool, they can be seen crawling on the surface of the feces. Thus, the diagnosis of hydatid disease is made by the infectious disease specialist or general practitioner through the evaluation of signs and symptoms that may arise, imaging and laboratory tests, and the Casoni reaction is the laboratory test used to confirm the diagnosis of hydatid disease, since identifies specific antibodies in the person's body. A complete blood cell count performed in-house (Vet ABC Animal Blood Analyzer; Heska, Loveland, Colorado, USA) revealed a mildly increased hemoglobin concentration [190 g/L; reference interval (RI): 119 to 180 g/L] and hematocrit (0.58 L/L; RI: 0.37 to 0.55 L/L). When handling live canines, their feces, pelts or carcasses: Severity of symptoms depends on if and where the juvenile worms form cysts: Consult your doctor if you have health concerns after handling wolf or coyote carcasses, Cysts found in cervids can infect pet dogs, Once infected, pet dogs can be a source of infection to you and your family.

Infected cervids often have large fluidfilled cysts in lungs or liver - these cysts are NOT infectious to people. If left untreated, you could die from this infection. In some cases, surgical removal of the cyst may also be indicated, especially when it is very bulky and is present in an easily accessible location. Foxes, coyotes, and the wild rodents upon which they prey are important in the lifecycle of this parasite. Sometimes a thin needle is used to puncture the cyst and take out fluid to test for the Echinococcus infection. Occasionally they can be the size of a football, especially in humans. Hydatid disease is caused by the formation of cysts following ingestion of Echinococcus granulosus eggs.

B Liver masses opened. National Library of Medicine CWD is relatively widespread in Colorado. Worldwide, considerable morbidity and mortality are associated with cystic (due to E. granulosus) and alveolar (due to E. multilocularis) hydatidosis, and in South America there are foci of polycystic disease due to E. vogeli and E. oligoarthrus. The eggs can remain viable in the soil for several months or years and are normally consumed by pigs, cattle, goats or sheep, where hydatid cysts develop in the liver and lungs, which can be consumed by dogs, especially in places where animals are raised for slaughter.

Tapeworms usually live in hosts such as sheep and dogs. However, the perpetuation of infection between livestock and dogs increases the risk of human infections, and the infection is very difficult to treat. Excisional biopsies of the lesion were obtained for histopathology. Since the discontinuation of compulsory worming for farm dogs in the late 1980s there has been a steady increase in the number of cases of human Hydatid disease - there are around 10 cases reported each year. The segments resemble grains of rice or cucumber seeds and are about 1/2 (12 mm) long and about 1/8 (3 mm) wide. Hydatid Disease.

When secondary or dead-end hosts ingest tapeworm eggs, the newly-hatched tapeworms migrate out of the intestines into the bloodstream and are deposited in various organs around the body, where they form cysts. The final diagnosis was hepatic alveolar echinococcosis. As a result, 13 humans that came in contact with this dog at 2 to 6 mo of age were tested for antibody to E. multilocularis using 3 different screening enzyme-linked immunosorbent assays (ELISAs) [EgHF-ELISA, Em2-ELISA, and Em18-ELISA (8)].
