Abstract
A total of 41 clinical samples (vesicle/tongue/foot/nasal epithelium) from Indian gaur, deer, spotted deer, nilgai, chowsinga, bison, black buck, elephant, sambar deer were collected in 50% phosphate buffered saline/glycerol medium (pH-7.5) during suspected FMD outbreaks. Supernatants of homogenized clinical samples were used in a serotype differentiating antigen detection ELISA and samples found negative were further subjected to multiplex PCR (mPCR). A total of 3/11 (27.2%) samples from Indian gaur, 2/7 (28.5%) chital deer, 5/5 (100%) nilgai, 2/2 (100%) black buck were found positive for serotype O in antigen detection ELISA. A total of 3 ELISA-negative samples from spotted deer, 2 from bison and 2 from sambar deer were found positive for serotype O in mPCR. The VP1 region-based phylogenetic analysis indicated the involvement of both O/ME-SA/Ind2001 and PanAsia lineage of serotype O in the outbreaks. The wildlife species infected with FMD may pose further threat to the surrounding domestic livestock.
