Malic Dehydrogenase Patterns in Different Strains of 'Schistosoma japonicum' and Subspecies of 'Oncomelania hupensis'.

摘要

Malic dehydrogenase (MDH) of the Formosan, Philippine and Indonesian strains of Schistosoma japonicum and 3 subspecies of snails, Oncomelania hupensis formosana, O. H. quadrasi, and O. h. lindoensis were identified by disc electrophoresis with 10.5% acrylamide gel columns using tris-malic buffer. Male worm extracts of S. japonicum demonstrated 3, 2 and 2 clear MDH patterns and female worm extracts showed patterns of 2,1 and 1 for Formosan, Philippine and Indonesian strains of the parasite, respectively. MDH patterns were the same for all 3 subspecies of snails; one major and one minor band being found in all. (Author)
