Short Communication


The differences or similarities among different isolates of Trypanosoma evansi through endonuclease profile was identified in the present study. The repetitive nuclear DNA of T. evansi isolated from infected cattle, buffalo and equine blood was initially amplified by PCR using specific primers. A panel of restriction enzymes, EcoRI, Eco91l, HindIII and PstI were for complete digestion of PCR products. Agarose gel electrophoresis of digested product did not show cleavage fragments and only single DNA band of the original size was visible in the ethidium bromide stained agarose gel. This indicated that the 227 bp PCR product from repetitive sequence had no site-specific cleavage sites for the REs used in this study. No heterogeneity in the repetitive nuclear DNA restriction endonuclease profile among the different isolates was recorded.
