Footrot is a contagious disease affecting the interdigital epidermis and living tissues of digits of sheep and goats. The disease is being reported in Andhra Pradesh (AP) and Telangana states of India regularly causing significant economic loss to the sheep husbandry. The causative agent is the anaerobic, gram negative bacteria, Dichelobacter nodosus. A total of sixteen isolates of D.nodosus have been recovered from footrot positive clinical samples collected from AP and Telangana state and further confirmed by PCR targeting 16Sr RNA gene. The isolates were further processed for virulence characterization by Gelatin gel test and elastase test. Gelatin gel test revealed 56.5% of isolates as virulent, 31.25% of isolates as Intermediate and 12.25% of isolates as benign. Whereas elastase test identified only 18.75% of isolates as virulent, 12.5 % of isolates as intermediate, 12.5% of isolates as benign, the rest 56.25% of the isolates did not exhibit any elastase activity.
