New insights into diagnosis of Platynosomum fastosum (Trematoda: Dicrocoeliidae) in cats.

Abstract

Platynosomum fastosum is a hepatic trematode which causes the so-called lizard poisoning in cats. This parasite is reported in tropical and sub-tropical areas infecting the liver, gallbladder, and bile ducts of cats. Despite its clinical importance, the diagnosis of P. fastosum has been poorly investigated so far. In this study, three cases of infection by P. fastosum in cats are reported. The FLOTAC technique was utilized for the first time in the detection of eggs of this parasite. Three cats (two males and one female), being one of them with a history of diarrhea and vomiting, were diagnosed positive for the presence of P. fastosum eggs through the FLOTAC technique. In conclusion, this study provides important and new insights into the diagnosis of P. fastosum in cats, expanding the geographical knowledge of this parasite in Brazil.
