Platinosomíase em felinos domésticos: um diferencial para obstrução biliar

The platinosomiase is a disease the hepatobiliary system of domestic felines being caused by trematode Platynosomum fastosum. The life cycle of the parasite includes the presence of three intermediate hosts (snails, terrestrial isopodes, lizards or frogs). The cat is considered definitive host of the parasite and acquires the infection eating a vertebrate intermediate host containing metacercariae. The adult parasites generally inhabit the liver, gallbladder and bile ducts of cats. The severity of clinical manifestations depends mainly on the number of flukes in the biliary tract. Many animals are asymptomatic or exhibit nonspecific clinical manifestations such as anorexia, lethargy, weight loss, vomiting and diarrhea. In large infestations can occur biliary obstruction resulting in jaundice, cirrhosis, hepatitis cholangiohepatitis and even death. The definitive diagnosis is accomplished through by the detection of fluke eggs in feces or through laparotomy and liver biopsy. Treatment should be based on the use of anthelmintic for the elimination of the parasite and supportive therapy for the animal. Prevention is difficult due to predatory nature of the cat. The control can be accomplished through periodic fecal examinations
