Sex dependent alterations in the protein characterization patterns of Haemonchus contortus.

The aim of the study was to highlight the sex dependent differences in the electrophoretic protein patterns of male and female Haemonchus contortus worms SDS based polyacrylamide gels of both male and female worms were run side by side for comparison. A total of 33 and 35 polypeptides were detected in polyacrylamide gels stained with coomassie brilliant blue R-250, respectively. Besides many of the fundamental homologies in protein profile, some of the polypeptides specific to either sex were also observed. Most of the characteristic polypeptides were of low molecular weight. These polypeptides needs deeper unrevealing regarding the nature of protein, through well planned zymographic studies, so as to ascertain the true nature and/or type of protein involved in those bands. This will help us in better understanding of parasite immunology and sex influenced differences amongst the worm and the possible variations in their pathogenesis contributed thereof, if any.
