Objective: To analyze the subtype of porcine endogenous retrovirus (PERV) in two species of Chinese pigs-Wu zhishan pig and Banna minipig inbred; the total number of pigs being eighty six.
Methods: Three primers which are specific for the three PERV subtypes (subtypes A, B and C) were used to amplify the genome DNA extracted from the pigs.
Results: In all tested pigs' genome, subtype C was not found; in 77.9% pigs, double positive envAB were found; in 22.1% pigs, only A or B was found.
Conclusion: In the genome of peripheral leukocytes from Wuzhishan pig and Banna minipig inbred, only subtypes A and B exist, and envAB predominate.
