Molecular characterization of a Trichinella spiralis elastase-1 and its potential as a diagnostic antigen for trichinellosis

摘要

Sequence alignment of elastase gene ( ) with other species or genotypes. Clustal X and BOXSHADE were used to analyze the sequences, obvious differences were observed in different species/genotypes. Black shading represents the residues identical to TsEla, and grey shading shows the conservative substitutions
