“…These values are lower than we observed in the Primorsky Krai. In the closely related species Meles meles Linnaeus, 1758, inhabiting Europe, the prevalence of this parasite also varied in different regions, for example, from 6.2% in the Balkans (Klun et al, 2019) and up to 25% in the central part of Russia (Andreyanov, 2014).…”

Nematodes of the genus Trichinella cause trichinosis, which is a zoonotic disease of humans, wild and domestic animals. In the Russian Far East, trichinosis has a natural focal character. Carnivorans (Carnivora), living in natural ecosystems including Protected Areas, are the main hosts of Trichinella. The peculiarities of Trichinella circulation in natural environment and the parasite prevalence in wild animals of different species remain poorly understood as well as the species composition of the Trichinella genus in the studied region. Muscle samples were obtained from 731 specimens belonging to 14 species and four families (Mustelidae, Ursidae, Felidae, and Canidae) in Primorsky Krai (Russia) in 2010-2020 and examined on Trichinella. The parasites were found in 124 specimens belonging to 11 species. The highest Trichinella prevalence was observed in Vulpes vulpes (64%), Ursus arctos (57%), and Lynx lynx (50%). A relatively high ratio of infected animals (30-50%) was found in Nyctereutes procyonoides, Ursus thibetanus, and Prionailurus bengalensis. The parasite prevalence was relatively low in the representatives of the Mustelidae family. Three species of the genus Trichinella (T. nativa, T. spiralis, and T. pseudospiralis) were found for carnivorans inhabiting the study area. Trichinella nativa was found the most frequently in natural ecosystems. Trichinella pseudospiralis was discovered for the first time both for P. bengalensis and for the area of the Primorsky Krai. The Carnivora ecology contributes to a high risk of infection by Trichinella species. The parasite prevalence was high in the species that combined different feeding habits, i.e. they acted as predators, scavengers and cannibals. A relatively long life expectancy also contributed to a higher risk of infection. A relatively high parasite prevalence of Trichinella in wild animals in the Primorsky Krai was caused by the high biological diversity of carnivorans. Our results are important for understanding the trichinosis circulation in natural communities and the possibility of human infestation. These data are also important for managing the carnivorans' populations in the Russian Far East. The issues of nature conservation in regard to the trichinosis circulation are also important for threatened animals, including Panthera tigris altaica.

“…Trichinosis is a widespread natural focal disease dangerous to humans (Campbell, 1983;Murrell, 2001;Pozio, 2005). In the wild, invasion circulates among carnivorans, primarily representatives of the order Carnivora (Britov, 1995;Skírnisson et al, 2010;Klun et al, 2019).…”

“…So far, surveillance and monitoring of Trichinella spp. in domestic (pigs and dogs) and wild animals (wild boar, Sus scrofa; red foxes, Vulpes vulpes; golden jackals, Canis aureus and; wolves, Canis lupus) was carried out in some endemic districts in Serbia (Klun et al, 2019;Dmitrić et al, 2017;Ćirović et al, 2015;Teodorović et al, 2014;Zivojinovic, 2013;Zivojinovic et al, 2010;Zivojinovic et al, 2009). An investigation was also focused on the transmission pathways of Trichinella species (Živojinovic et al, 2015).…”

Background. Trichinellosis is zoonotic disease caused by parasites of the genus Trichinella, which have a cosmopolitan distribution. In the Balkan region, including Serbia, trichinellosis is endemic. Although trichinellosis shows a decreasing incidence in Serbia, this disease remains a serious problem for human health and animal husbandry. Scope and Approach. To prevent and control Trichinella spp. infections in domestic and sylvatic animals, risk analysis for these zoonotic parasites should be conducted. In Serbia, a limited number of Trichinella have been identified to the species level so far. An institutional, multi-sectoral surveillance system, supported by an adequate legal framework for the detection, surveillance, prevention, control and reporting of this infection in animals and humans, harmonised with the EU legislation, is a priority. Key Findings and Conclusions. One of the main goals of the Serbian veterinary and public health services should be progressive improvement of animal rearing practices, food safety, and hunters' and consumers' education through the "One-health" approach.

“…At present, there are 10 recognized species of Trichinella around the world and three additional genotypes that have not yet been identified as distinct species ( Korhonen et al, 2016 ; Sharma et al, 2020 ). Most species infect only mammals ( Klun et al, 2019 ; Bilska-Zając et al, 2020 ), including marine mammals ( Tryland et al, 2014 ; Pasqualetti et al, 2018 ). However, Trichinella pseudospiralis Garkavi, 1972 also infects birds, and Trichinella zimbabwensis Pozio et al, 2002 and Trichinella papuae Pozio et al, 1999 infect reptile hosts ( Korhonen et al, 2016 ).…”

Background Trichinellosis is a zoonotic disease with a worldwide distribution. It is caused by several species of nematodes in the genus Trichinella. Trichinella spp. are transmitted through predation or carrion consumption and occur in domestic and sylvatic cycles. In humans trichinellosis occurs due to the consumption of raw or undercooked, infected meat and is mainly associated with the household slaughter of pigs or the consumption of game animals without veterinary inspection, a cultural practice that is difficult to resolve. Therefore, knowledge of this parasite’s reservoir is relevant for better implementing public health strategies. The aim of this study was to assess the presence of Trichinella sp. in several carnivore and omnivore vertebrates in central-southern Chile. Methods We collected muscle tissue from a total of 53 animals from 15 species and were digested to detect Trichinella larvae which were further identified to species level using molecular techniques. Results We detected Trichinella larvae in Leopardus guigna (Felidae) and Galictis cuja (Mustelidae). We identified the larvae collected from L. guigna as Trichinella spiralis, but we were unable to molecularly characterize the larvae from G. cuja. This is the first record of Trichinella in a native mustelid of South America and the first record of T. spiralis in L. guigna. This study identified two novel hosts; however, further work is needed to identify the role that these and other hosts play in the cycle of Trichinella in Chile.
