| [polymorphism of the cox1 gene in bird schistosome cercaria isolates (trematoda, schistosomatidae) from ponds of moscow and moscow oblast]. | polymorphism of a 8 10-bp mitochondrial cox1 gene region was studied in 16 cercaria isolates of bird schistosomes (family schistosomatidae), which were collected in water bodies of moscow and moscow oblast and represented three species: trichobilharzia szidati, t. franki, and t. regenti. a substantial predominance of at (65.4%) was characteristic of the cox1 sequences in all three species. rare single nucleotide substitutions determined low (0.2-0.9%) intraspecific nucleotide and amino acid sequ ... | 2010 | 20795503 |
