摘要：Introduction. The highest risk of trichinellosis for human is considered in eating meat products containing live larvae,
mostly from wild boars or pigs. Spreading of Trichinella spp. may occur in various ways, one of which is transmission by
vectors. The rat is considered to be the most common vector for Trichinella parasite. The population of rats living on pig
farms can play an important role in maintaining or spreading the parasite to other animals.
Objective. The aim of presented survey was to investigate the occurrence of Trichinella spp. in rats on farms with pigs
infected with this parasite.
Materials and method. From pig farms selected for study, the muscles of collected rats were investigated by magnetic
stirrer digestion method to assess occurrence of Trichinella in the rat population. Isolated Trichinella parasites were identified
under stereomicroscope and multiplex PCR were performed for species identification.
Results. Rats infected with Trichinella spp. were discovered on three of five investigated pig farms. The mean extent of
invasion in rats from the studied farms was 23.33%. The calculated medium intensity of invasion was 4.09 lpg (larvae per
gram) (SD 5.41). All larvae of Trichinella discovered from rats were identified as T.spiralis.
Conclusions. The results obtained indicate that in farms with a high prevalence of Trichinella invasion in pigs there are
very likely to be found rats infected by this nematode. This suggests possibility to maintain the invasion in herd and spread
into neighborhood farms.
