Domestic and sylvatic trichinellosis have frequently been documented in European regions of Russia, with the highest prevalence reported in wolves (Canis lupus). From 1998 to 2000, 75 carcasses of wolves shot by hunters were tested for Trichinella larvae, and 73 (97.3%) of them were found to be positive. This very high prevalence of infection, the highest ever detected in a natural population of carnivores, could be explained by the human impact on the natural ecosystem. In fact, the diet of wolves living in the region under study mainly consists of carcasses of dogs and wolves, which are left in the forest or used as bait by hunters.

Examination of 627 wild animals--raccoon dogs (Nyctereutes procyonoides), red foxes (Vulpes vulpes), European lynxes (Lynx lynx), brown bears (Ursus arctos), wolves (Canis lupus), and badgers (Meles meles)--revealed Trichinella spp. The prevalence varied according to geographical region of Finland (north; southwest, SW; and southeast, SE) and was the highest among lynxes (70%, SW). The risk of trichinellosis was higher in the SE (odds ratio, OR, 19.4) and SW regions (OR 14.3), as compared with the northern region (OR 1), with no difference between the former 2 regions. Foxes (OR 2.1) and lynxes (OR 1.9) had a higher risk than raccoon dogs (OR 1) of being infected. The distribution of different Trichinella species was evaluated in 87 wild and domestic mammals by multiplex polymerase chain reaction. Trichinella spiralis was detected more often in domestic and synanthropic animals than in sylvatic hosts. Trichinella nativa was detected only in wildlife. Trichinella pseudospiralis was found both in sylvatic and synanthropic hosts. Trichinella britovi was detected only in mixed infections with other Trichinella species. The raccoon dog was the sole host for all 4 Trichinella species and also carried the most intense infections.

Samples of muscle from 120 black bears (Ursus americanus), 11 grizzly bears (Ursus arctos), and 27 wolves (Canis lupus) collected in the Dehcho Region of the Northwest Territories from 2001 to 2010 were examined for the presence of Trichinella spp. larvae using a pepsin-HCl digestion assay. Trichinella spp. larvae were found in eight of 11 (73%) grizzly bears, 14 of 27 (52%) wolves, and seven of 120 (5.8%) black bears. The average age of positive grizzly bears, black bears, and wolves was 13.5, 9.9, and approximately 4 yr, respectively. Larvae from 11 wolves, six black bears, and seven grizzly bears were genotyped. Six wolves were infected with T. nativa and five with Trichinella T6, four black bears were infected with T. nativa and two with Trichinella T6, and all seven grizzly bears were infected with Trichinella T6 and one of them had a coinfection with T. nativa. This is the first report of T. nativa in a grizzly bear from Canada. Bears have been linked to trichinellosis outbreaks in humans in Canada, and black bears are a subsistence food source for residents of the Dehcho region. In order to assess food safety risk it is important to monitor the prevalence of Trichinella spp. in both species of bear and their cohabiting mammalian food sources.

Trichinella infections are endemic in the Balkan region of Europe. Though trichinellosis and agents thereof are serious problems for human health and animal husbandry, only a limited number of Trichinella isolates from Serbia have been identified at the species level so far. The aim of the present study was the surveillance and monitoring of Trichinella in domestic pigs and wild animals from the endemic district of Branicevo. Investigations performed during the 2009-2010 period revealed Trichinella infections in 344 out of 282,960 (0.12%) domestic pigs. Among wildlife, Trichinella infections were detected in 11 out of 94 (11.7%) wild boars (Sus scrofa), 7 out of 57 (12.3%) red foxes (Vulpes vulpes), 7 out of 13 (53.8%) golden jackals (Canis aureus), and in all three examined wolves (Canis lupus). Trichinella spiralis and Trichinella britovi were the only two species identified. T. britovi was identified in 31% of isolates from wildlife of the Branicevo district and T. spiralis was found in 53% of wild animals; mixed infections were observed in 16% of the animals examined. Findings form the basis of an information campaign for veterinary services, pig owners and the hunter's associations about the risk of the transmission of these zoonotic agents. The application of control programs as established at the Veterinary Specialist Institute of Pozarevac resulted in a decline in Trichinella infections among domestic pigs and the absence of human trichinellosis in the last three years in the Branicevo district.

Trichinellosis is a worldwide disease caused by nematode worms of the genus Trichinella, frequently diagnosed in Israel. However, the identity of the Israeli isolates have not been studied. Here we describe the molecular characterization of 58 isolates collected from jackals (Canis aureus), wild boar (Sus scrofa), foxes (Vulpes vulpes) and a wolf (Canis lupus) in central and northern Israel. Isolates were analyzed using the multiplex PCR analysis encompassing expansion segment V (ESV) and internal sequence 1 (ITS-1) markers, which identified 52 of the 58 samples. Out of the six unidentified samples, four were successfully identified using extended PCR assays for ESV and ITS-1, developed in this study. Our analysis identified 44 isolates as T. britovi, 8 as T. spiralis, four mixed infections, and two isolates were not identified. Clonal analysis of the ITS-1 sequences from six isolates confirmed the initial identification of four mixed infections. These results show that the prevalent species in Israel are T. britovi and T. spiralis, with nearly 7% (4 of 58) incidence of mixed infection.
