title: Species differentiation in Caenorhabditis briggsae and Caenorhabditis elegans.
abstract: Identification of five laboratory strains (1-5) of putative Caenorhabditis briggsae was undertaken. Examination of the male bursal ray arrangement, mating tests with males of Caenorhabditis elegans, malate dehydrogenase zymograms, and SDS polyacrylamide electrophoresis demonstrated that strain 4 was C. briggsae and the others were C. elegans.
