Abstract
Nematodes of the genus Trichinella are important zoonotic parasites present throughout Romania. This study aimed to assess the status of Trichinella species in wild animals in Romania over the past 30 years. A literature review of original studies concerning the only two species (out of the four in Europe) of Trichinella (T. spiralis and T. britovi) confirmed in wildlife from Romania was conducted and corroborated with the results of our original research concerning the topic. This review article has shown that, in Romania, European minks were infected with T. spiralis, while wolves, European wild cats, Eurasian lynx, golden jackals, stone marten, and European badgers were infected with T. britovi, respectively. Both Trichinella species have been identified in foxes, bears, wild boars, and ermines, but mixed infections have been found only in European polecats. Trichinella infection is still significantly present in Romania, infecting several wild omnivorous and carnivorous species in an equal manner, with different prevalence rates over the years. Regarding the spatial distribution of T. spiralis and T. britovi in Romania, both species can be found all over the country, but in wild animals, T. britovi is the most prevalent.
