ABSTRACT

Ptychobothridean genera like Senga and Circumoncobothrium are the common parasites of fresh water fishes. The genotypic study of these parasites was taken by RAPD. The RAPD profile of these two parasites were not similar to each other as depicted by the band pattern in picture. These results suggest the presence of inter-specific polymorphism among cestode parasites of two different genera for RAPD analysis. The present study demonstrated that genetic differentiation of cestode parasites could be accomplished on the basis of genomic variation with polymorphic band pattern using RAPD. All the detected bands (PCR product) were polymorphic and band size ranged from 500-5000 bp in length. The RAPD of profiles using GBO-31, GBO-32, GBO-33, GBO-34, GBO-35 and GBO-36. Primers were able to characterize inter-specific polymorphism among the two genus ( Senga and Circumoncobothrium ). Genetic analysis suggests that Senga and Circumoncobothrium show genetic diversity with respect to RAPD patterns using all the six primers used for the present study. The genetic distance between the analyzed genuses ranged from 0.14 to 0.80. The differentiation of the two parasites on the basis of genetic markers could greatly facilitate study on the biology of these parasites.
