Sylvatic Trichinellosis in Croatia- potential risk for human infection

Prevalence and situation in endemic regions considering rural trichinelosis in Croatia is well defined. On the other hand sylvatic cycle occurs in nature all over the world among carnivores with cannibalistic and scavenger behavior. Wild animals can be source of infection at two levels: directly, by consuming the meat from infected animals or indirectly due to infected wild animals are source domestic pig. Epidemiological surveys has been carried out in order to understand the role of different animal species as indicators of sylvatic trichinellosis and the role of game animals as a source of infection for humans. As indicator spices we have used wolves, red foxes and badgers and as representative of game animals wild boars and bears were used. Muscle samples were artificially digested and Trichinella larvae were collected for further analysis with multiplex polymerase chain reaction (PCR) at the species level. Trichinella britovi has been detected in wolves, foxes, badgers, wild boars and bears as the typical species of sylvatic Trichinella, but interestingly in one badger from Slavonia region T. spirals was detected. In the same region T. britovi was identified in pig and both species of Trichinella were detected in another case. The most interesting data is frequent detection of T. britovi in animals from Lika region. Results on determination of Trichinella at species level by multiplex PCR clearly shoved that T. brittovi is most prevalent etiological agent of wild animals, especially in Lika region, but finding T. spiralis in badger and T. britovi in domestic pigs strongly suggest a link between the sylvatic and domestic cycle in Slavonia.
