Trichinellosis in wild boars in Croatia

In order to study the epidemiology of trichinellosis with special emphasis on wild boars a large scale study was performed. The goals of the study were to define the prevalence of trichinellosis in wild boars, to determine the etiological agents and to evaluate the use of ELISA in epidemiological investigation. Totally 1498 diaphragms were collected during three years period from 1498 (1003 diaphragms during the first collection period, 495 diaphragms during the second collection period) Isolated Trichinella larvae were also analysed by multiplex PCR in order to understand possible transmission between domestic pigs and wild boars. The prevalence in wild boars among the first study, mainly from non-endemic region was less than 0, 1% while among the second study the prevalence was higher (1, 6%). Studies on genotypes suggest that Trichinella britovi is the most common etiological agent in wild boars found in non endemic region while T. spiralis and T. britovi were common in the endemic region. The presence of T. spiralis in wild boars presented mostly in the domestic habitat suggesting a link between the sylvatic and domestic cycle. Another important conclusion was the comparison between the accuracy of results of ELISA with Western Blotting and the real muscle larvae burden after artificial digestion.
