Synopsis
CAPC Recommends Treating intestinal Echinococcus spp. infections in dogs with praziquantel at dose of 5 mg/kg either orally or injectable. Educating owners of the risk of Echinococcus spp. to humans, emphasizing prompt fecal removal and disposal to reduce the environmental risk of the parasite to pets and people.
Species
Canine Echinococcus granulosus sensu lato E. canadensis E. granulosus sensu stricto Echinococcus multilocularis Feline Echinococcus multilocularis
Disease
Adult Echinococcus spp. in the lumen of the small intestine cause no disease in the majority of dogs and cats. Dogs have been occasionally reported to have bloody diarrhea.
Prevalence
E. granulosus has a worldwide distribution, with the highest prevalence in parts of Eurasia, north and east Africa, Australia, and South America. Infections have also been reported in dogs in North America, albeit at a lower prevalence.
Diagnosis
Due to the small size of Echinococcus spp. adults and their low number of body segments, it is extremely unlikely for proglottids to be observed grossly. Fecal flotation with centrifugation Diagnosis of patent Echinococcus infections via centrifugal fecal flotation can be challenging as eggs are quite dense.
Treatment
Praziquantel is approved at 5mg/kg orally or subcutaneously for elimination of intestinal stages of adult Echinococcus spp. in dogs. Canine alveolar echinococcosis carries a guarded prognosis.
Control and Prevention
Prevention of predation and scavenging activity by keeping cats indoors and dogs confined to a leash or fenced in a yard will limit the opportunity for acquiring infection with Echinococcus spp. via ingestion of infected intermediate hosts. In dogs that are allowed outside or that are known to have predatory behavior, a heartworm preventive containing praziquantel will routinely treat infections with Echinococcus spp. and other cyclophyllidean cestodes.
Public Health Considerations
Although the overall risk of human infection with Echinococcus spp. in North America is low, dogs and cats infected with these tapeworms create a zoonotic risk. The eggs shed in the feces of an infected dog or cat are immediately infectious to the intermediate host.
