Serologic survey of trichinellosis in wild mammals kept in a Mexico City Zoo

摘要: A serologic survey of Trichinella infection was carried out to determine the prevalence this parasitosis among wild mammals kept in captivity at Chapultepec Zoo. This prompted by necropsy finding a heavy Canadian polar bear (Ursus maritimus) that had been Zoo for more than 11 years. The parasites recovered were identified as T. nativa (T2). study based on ELISA and Western blot analysis performed serum samples from two bears (U. maritimus), six wolves (Canis lupus); nine foxes (Urocyon cinereoargenteus); seven coyotes latrans); jaguars (Panthera onca); ten lions leo); tigers tigris); panthers pardus); eight leopards lynxes (Lynx rufus); five pumas (Felis concolor); one yagouaroundi yagouaroundi); ocelot pardalis). In these assays, 25% 27% studied positive using total muscle larva extract (T2) or spiralis (T1), respectively. When (T1) excretory/secretory products surface/stichosomal antigens used, 15 13% positivity obtained reactivity rates different groups varied 83%, having highest rate. sera showed an antigenic recognition pattern characteristic animals infected with Trichinella.
