The relevance of evolutionary genetics for identification of Trichinella sp. and other pathogens at the strain, subspecies and species levels

摘要

In the specific field of Trichinella research, the impact of evolutionary methods has been until now limited. This is all the more distressing, since this group of parasites is characterized by hard taxonomical problems. Moreover, for the epidemiological tracking of Trichinella populations, high-discriminating genetic typing, conveniently analyzed by population genetic methods, could be of considerable help. With no additional efforts, many molecular data are already available and could be used for retrospective analyses able to solve many taxonomical problems. It is desirable that coming studies are specifically designed according to evolutionary genetics principles and the question under study (sample size, selection of the appropriate marker).Key words: genetics / evolution / phylogeny / Trichinella
