title: Differentiation of species and life cycle stages of Brugia spp. by isoenzyme analysis.
abstract: The isoenzyme patterns of glucose phosphate isomerase and phosphoglucomutase of 3 species of Brugia, B. pahangi, subperiodic B. malayi, and B. patei, and 3 life cycle stages, adult, third-stage larva, and microfilaria were compared using the technique of isoelectricfocusing on polyacrylamide gels. The results demonstrated that the adults of all 3 species could be identified from one another and that differences existed between the sexes of any one species. Hybridization between B. pahangi and B. patei could be detected in the progeny of the cross. Both the third-stage larvae and microfilariae of B. malayi and B. pahangi were differentiated and the epidemiological significance and the application of these findings to arthropod-borne filarial infections were discussed.
