| intra-species variability in its-1 sequences of haemonchus contortus isolated from goats in west bengal, india. | this study evaluated the existence of different genotypes of haemonchus contortus prevailing among goats in west bengal, india. these parasites were isolated from the abomasum of goat intestine and the molecular characterization was performed by comparing variation of nucleotide sequences of the internal transcribed spacer 1 (its-1) gene region. single-strand conformation polymorphism (sscp) analysis of its-1 amplified product showed the presence of three distinct conformations both in male and ... | 2010 | 20804642 |
