Small ruminant lentiviruses cause slow progressive diseases in the sheep and goats and are prevalent in India. The present investigation was carried out to detect the Maedi Visna in the sheep and goats of North Indian states. A total of 1380 biological samples (serum-460, blood-389, lung tissue-531) were collected from different places of North India and screened for presence of SRLVs nucleic acid and antibodies. Sero-prevalence of 12.17% was observed by cELISA for the SRLV antibodies. Sero-positivity in sheep (16.02%) was higher than goats (4.05%). MVV nucleic acid was detected in 6.85% samples by nested PCR and positivity was higher in sheep (8.09%) than goats (1.69%). Sequencing of the PCR products showed more homology with the sequences reported from United Kingdom. In conclusion, small ruminants of India harbours the MVV and systematic investigation is required to know its status and economic impact on the small ruminant farming.
