The first report of Trichinella pseudospiralis presence in domestic swine and T. britovi in wild boar in Bosnia and Herzegovina

Abstract

The Balkans is endemic for nematodes of the genus Trichinella in both domestic and wild animals. The high prevalence of these zoonotic pathogens in animals linked with the food habits to consume raw meat and meat derived products resulted in a very high prevalence of trichinellosis in humans living in this European region. In spite of numerous epidemiological investigations carried out in this region, very few information is available on the Trichinella species circulating in Bosnia and Herzegovina. Trichinella spp. larvae were isolated from a domestic pig reared in a backyard and from a hunted wild boar whose meat had been the source of trichinellosis in one case. Both Trichinella pseudospiralis and T. spiralis have been identified in the domestic pig, whereas, T. britovi was detected in the wild boar. While, T. spiralis is the Trichinella species most frequently detected in domestic pigs, T. pseudospiralis has been previously documented in domestic pigs only three times in Russia, Slovakia and Croatia. The detection of T. britovi in the wild boar confirms that this nematode is the most frequent species circulating among wildlife of Europe.

Epidemiologic Survey on Toxoplasma gondii and Trichinella pseudospiralis Infection in Corvids from Central Italy

“…In Europe, T. pseudospiralis was found in different species of wild animals, such as birds of prey, wild boars, raccoons and red foxes, and was also reported in domestic pigs and rats [2,20,[45][46][47][48]. Nevertheless, it is less common than encapsulated species and more common in mammals than in birds [20,23,24,48].…”

Trichinellosis in Serbia and possibilities to improve control measures

“…T. spiralis and T. britovi are the two main species circulating in Europe (Pozio et al, 2009) and the Balkan countries bordering Serbia (Blaga et al, 2007). T. pseudospiralis has been documented in domestic pigs in Croatia and Bosnia and Herzegovina (Santrac et al, 2015;Beck et al, 2009), but there is still no available data for Serbia.…”

Insight into Trichinella britovi infection in pigs: effect of various moderate infectious doses on larvae density and spatial larvae distribution in carcasses and comparison of the detection of anti-T. britovi IgG of three different commercial ELISA tests and immunoblot assay

“…Among the 10 named and known species of Trichinella (Trichinella spiralis, Trichinella nativa, Trichinella britovi, Trichinella pseudospiralis, Trichinella murrelli, Trichinella nelsoni, Trichinella papuae, Trichinella zimbabwensis, Trichinella patagoniensis, and Trichinella chanchalensis) and the three characterized genotypes (T6, T8 and T9) [2][3][4], T. spiralis, T. britovi and T. pseudospiralis have been con rmed as the causative agents of natural Trichinella infections in European breeding pigs. Infections induced by T. pseudospiralis were only con ned to single pigs in Slovakia, Croatia, Bosnia and Herzegovina and Spain [5][6][7][8]. In contrast, natural infections of domestic swine have been proved to have been caused by both T. spiralis and T. britovi in many countries in Europe; however, the frequency of their occurrence differs signi cantly.…”
