| Summary: | Trichinosis is a parasitic zoonosis that is caused by parasitic larvae of the
genus Trichinella. Serbia is among the countries in which T. spiralis is
present, in addition to domestic animals, also in synanthropic and sylvatic
animals. This paper presents the results of investigations of the spread of
trichinosis among certain species of sylvatic and synanthropic animals, with
the aim to establish the role of wild animals in the natural cycle of
trichinosis in this country. A total of 155 samples of wild boar, foxes,
jackals, and rats were analysed. The samples were investigated through the
artificial digestion method using a magnetic stirrer in keeping with
Commission Regulation (EC) No 2075/2005. The isolated muscle larvae were
determined using the method of polymerase chain reaction (PCR). The
investigations established a relatively high prevalence of trichinosis in
foxes (5%) and jackals (8.33%) in the territory of Vojvodina. The degree of
infestation among carnivora in Serbia (10-30 larvae/10g) is much higher than
in countries where there is no trichinosis among domestic animals. The
prevalence of trichinosis among wild boar is not high, 0.82%, but a very high
degree of infestation was established in these animals (1100 larvae/g).
According to our results, the prevalence of trichinosis and the degree of
infestation in rats collected from pig farms with established trichinosis is
extremely high, the prevalence is higher than 80% with a degree of
infestation of 900 larvae/g. The isolated muscle larvae were determined as
belonging to the species T. spiralis. The spread of trichinosis is affected
to a large degree by poor socioeconomic conditions, inadequate education of
breeders, the absence of or unsatisfactory veterinary control, irregular
animal carcass removal. Trichinosis of domestic swine is widespread in Serbia
and it poses a significant risk to human health. The presented data indicate
that it is necessary to include measures for preventing the spread of
trichinosis from domestic swine to sylvatic animals among the measures that
are being implemented to cut down trichinosis among domestic animals. |
