Helminth infection in wild boars in Primorye, Russia.

Wild boars have a worldwide distribution and also have major economic, veterinary, and medical importance. Due to a small amount of data on the parasitic fauna of wild boars in the Russian Far East, especially in Prymorye territory, a post-mortem parasitic examination of 20 wild boars was provided. The general prevalence was 25%, and a total of six helminth species, including one larva stage, were found.

Origins, phylogenetic relationships and host-parasite interactions of Troglotrematoidea since the cretaceous.

In the current study, we raise the issue concerning origins and historical relationships of the trematodes from the families Troglotrematidae and Paragonimidae using phylogenetic analysis and molecular-clock method for estimating evolutionary rates. For the first time we provided 28S rRNA gene fragment (1764 bp) for the type species Troglotrema acutum - zoonotic trematodes that cause cranial lesions (troglotremiasis) in mustelid and canid mammals of the Central Europe, Iberian Peninsula, and North-West Caucasus. Molecular genetic analysis revealed that T.

Sequencing and genetic characterization of two strains Paramushir virus obtained from the Tyuleniy Island in the Okhotsk Sea (2015).

Paramushir virus belongs to Sakhalin virus genogroup within Orthonairovirus genus and is one of the poorly studied viruses with unknown pathogenicity. At the moment, only one nearly complete sequence of Paramushir virus genome, isolated in 1972, is available. Two new strains of PARV were isolated in 2015 from a sample collected at the Tyuleniy Island in the Okhotsk Sea and sequenced using a combination of high throughput sequencing and specific multiplex PCR.
