Abstract
The results of testing several primer combinations were used to choose an optimal pair for the amplification of the internal transcribed spacer 2 (ITS2) region of ribosomal DNA (direct: Tri58s F 5 CGG TGG ATC RCT TGG CTC GTA CG and reverse: AB28 Rr (CGA CCG CTT ATT GAT ATG C). This pair of primers yields a 900 bp PCR product. Comparative analysis of obtained ITS2 sequences, for 8 Trichinella isolates from different regions of the Russian Federation permits different species and individual genotypes of these parasitic nematodes to be validly distinguished.
