Mutation scan screening of Echinococcus granulosus isolates of Indian origin

During the present investigation a total of forty Indian animal isolates were screened by single strand conformation polymorphism (SSCP) collected from sheep, goat, cattle and buffalo. The result of the study indicated that nuclear variants of Echinococcus granulosus were present in both small and large ruminants. SSCP phenotypes of AgB, intron of actin II and Hbx-2 have been deduced. Presence of nuclear variants due to mutation of E. granulosus has been discussed depending on hypotheses imparted earlier in literature. High polymophism of AgB demands further investigation because the gene is related with immune evasion and infectivity. This communication reports for the first time the comparative profile of Indian goat, sheep, cattle and buffalo isolates of E. granulosus complex.
