title: Phenotypic differences in female Ostertagia circumcincta as demonstrated by isozymes hydrolyzing alpha-naphthyl acetate.
abstract: According to results of disc gel electrophoresis of homogenates prepared from individual female nematodes of the species Ostertagia circumcincta and subsequent staining of gel preparations, a maximum of 5 isozymes, hydrolyzing alpha-naphthyl acetate, were present. On the basis of resolution and mobility, these isozymes could be classified as 2 slow and 3 fast bands. Phenotypic differences were observed in the intensity of individual bands, as well as in the presence (or absence) of bands.
