              Abstract 
 
              Aim: To detect and 
              differentiate Capripox virus (sheeppox virus and goatpox virus) 
              infections by using 30 kDa RNA polymerase subunit (RPO30) gene 
              based PCR.Materials and Methods: Two capripox viruses' viz., sheep 
              pox virus (SPPV) and goatpox virus (GTPV) from clinical samples of 
              different outbreaks were detected and differentiated using capri 
              pox virus (CaPVs) genotyping PCR targeting the CaPV RPO30 gene. By 
              using the above PCR assay, a total of 54 scab samples from pox 
              disease outbreaks occurred in goats (n=21) and sheep (n=33) were 
              screened.
 Results: Out of 54 clinical samples, 43 [17 out of 21 
              (80.95%) goat scabs and 26 out of 33 sheep (78.78%)] were found 
              positive for capripox virus infection. All positive samples 
              yielded expected amplicon sizes of 172 bp for goatpox virus and 
              152 bp for sheep pox virus.
 Conclusion: The current study demonstrated that RPO30 gene 
              based PCR assay could be used for molecular epidemiology of 
              capripox virus infection and differentiation of causative agent 
              viz., sheep pox virus and goatpox virus.
 Key words: capripox virus, differentiation PCR, goat pox, 
              RPO30 gene, sheeppox
