[Prevalence of Trichinella spp. in red foxes and wild boars in the northwestern part of Poland].
The aim of the study was to establish in which degree wild boars and red foxes are reservoir of Trichinella spp. in North-West Poland. Research was carried out between 1997 and 2004 on 505 foxes and 56,462 wild boars in muscle samples. The muscle samples were examined using the digestion method. The average prevalence rate of Trichinella spp. infection of foxes was 4.4 %. Large differences of the infection rate in wild boars were observed. In the years 1999-2001 Trichinella spp. larvae were observed in 58 animals (0.2 %) and between 2002 and 2004 the Trichinella spp. prevalence in 227 wild boars was 0.9 %, demonstrating that the animals were 5.1 times more often infected than in 1999-2001. The growth of red fox population after the oral vaccination against rabies was probably the cause of this phenomenon.
