Molecular taxonomic study of Trichinella spp. from mammals of Russian Arctic and subarctic areas
Vol.4,No.1(2014)
Analysis of taxonomic affiliation of Trichinella species circulating in the Chukotka Autonomous Region and some subarctic areas of the Russian Federation showed that the representatives of T. spiralis and the Arctic trichinellas - T. nativa (genotype T2) and Trichinella sp. (genotype T6) can be found there. The partial sequences of Coxb (704 bp) of these Arctic Trichinella spp. from Russia differ from Coxb sequences of those genotypes (T2 and T6) deposited in NCBI GenBank (1-3 bp). The cultivated larvae of Trichinella sp., which were established from muscular tissue sample of stray cat (shot on the fur farm in Chukotka peninslula) differ at molecular level (Coxb) even more significantly; 21-24 bp difference between Trichinella sp. and T. nativa and 46-47 bp difference between the same isolate and T. spiralis were recorded.
