Sytuacja epidemiologiczna włośnicy w Polsce – I półrocze 2022 r.

Abstract

The aim of this study was to present the current situation of trichinellosis, basing on the results of examination of the tissues of animals huntedin Poland. Investigation was carried out from 1st January to 30th June 2022 in the Department of Parasitology and Parasitic Diseases of NationalVeterinary Research Institute in Poland. Samples were collected out of 103 wild boars (Sus scrofa) and one wolf (Canis lupus), originating from14 voivodeships. The study of wild boars muscle tissues revealed 89 positive samples, including 60 T. spiralis, 21 T. britovi, two T. pseudospiralis,and five mixed invasions with T. spiralis and T. britovi. In one case no amplification products were obtained. T. britovi was also found in the sample of wolf muscle tissue. This study emphasize the fact that trichinellosis in hunting animals is still a zoonotic threat, and should be closelymonitored.
