The present investigation was based on the sudden death of an Asian elephant (Elephas maximus) in Bonai Divison of Sundargarh forest range of Odisha, India. Bacterial enteritis in elephants is rarely reported according to the published cases and limited knowledge is available regarding etiology and pathogenesis of bacterial microflora in the large herbivores. It has been reported that the anatomy and physiology of the elephant gastrointestinal tract have many similarities to that of horse. So like enterocolitis in horses the microbial etiology in elephant was detected in this case. Routine microbial analysis of the samples collected from liver, lung, intestine and impacted food material revealed the presence of Salmonella species, Escherichia coli, Clostridial species and other enterobacterial organisms like Klebsiella sp. and Pseudomonas sp. Antimicrobial sensitivity pattern of the six isolates of E. coli, six isolates of Salmonellae and 4 isolates of Clostridium sp. were analysed and it was found that Enrofloxacin was highly sensitive followed by Gentamicin. While screening for biofilm formation all the 6 isolates of each Salmonella spp., E. coli and Clostridium species it was revealed that both E. coli and Salmonella spp. produced white color colonies on Congo Red Agar while clostridial species were found also negative with white colour colonies when isolated in anaerobic condition after cultivation with Robertson’s cooked meat medium and screened with Congo Red Agar. Further analysis on microbiological and molecular characterization is required.
