| morphological and molecular characterisation of gyrodactylus salmonis (platyhelminthes, monogenea) isolates collected in mexico from rainbow trout (oncorhynchus mykiss walbaum). | gyrodactylus salmonis (yin et sproston, 1948) isolates collected from feral rainbow trout, oncorhynchus mykiss (walbaum) in veracruz, southeastern mexico are described. morphological and molecular variation of these isolates to g. salmonis collected in canada and the u.s.a. is characterised. morphologically, the marginal hook sickles of mexican isolates of g. salmonis closely resemble those of canadian specimens - their shaft and hook regions align closely with one another; only features of the ... | 2011 | 22169222 |
