              Abstract 
 
				Aim: 
				The present 
				study was undertaken to develop a nucleic acid-based diagnostic 
				assay loop-mediated isothermal amplification assay (LAMP) 
				targeting highly conserved genomic regions of Capripoxvirus (CaPVs) 
				and its comparative evaluation with real-time polymerase chain 
				reaction (PCR). 
				Material and 
				Methods: 
				Lyophilized 
				vaccine strain of sheeppox virus (SPPV) was used for 
				optimization of LAMP assay. The LAMP assay was designed using 
				envelope immunogenic protein (P32) coding gene targeting highly 
				conserved genomic regions of CaPV responsible for causing sheep 
				pox, goat pox, and lumpy skin disease in sheep, goat and cattle 
				respectively. Serial tenfold dilution of SPPV recombinant 
				plasmid DNA was used for a calculating limit of detection. 
				Analytical sensitivity and specificity were performed. 
				Results: 
				The test 
				described is quick (30 min), sensitive and specific for 
				detection of CaPVs. The described assay did not show any 
				cross-reactivity to other related viruses that cause apparently 
				similar clinical signs. It was found to be ten times more 
				sensitive than conventional PCR however, 100 times less 
				sensitive than quantitative PCR (qPCR). LAMP assay results were 
				monitored by color change method using picogreen dye and agarose 
				gel electrophoresis.  
				Conclusion:
				LAMP 
				assay can be a very good alternative for CaPV detection to other 
				molecular techniques requiring sophisticated equipments. 
				Keywords:
				
				Capripoxvirus, 
				loop-mediated isothermal amplification assay, real-time 
				polymerase chain reaction, sensitivity, 
				
				specificity.
