PCR-based diagnosis of surra-targeting VSG gene: experimental studies in small laboratory rodents and buffalo.


Trypanosoma evansi, the causative organism of 'surra' expresses its variable surface glycoprotein (VSG) at early, middle and late stages of infection in animals. The variable antigenic nature of VSG caused by switching its expression type favours evasion from the host immune response and leads to chronic and persistent infection. Developing a polymerase… (More)
