Abstract: The objective of the present study was to identify the various bacterial causal agents (Salmonella spp. and E. Coli) in cattle calves that had diarrhea. Irrespective of the breed or age, cattle calves below 3 months of age exhibiting the typical clinical symptoms of diarrhea were presented at the Veterinary Clinical Complex, College of Veterinary and Animal Science, RAJUVAS, as well as in the nearby local region of Bikaner. A total of 45 diarrheal calves that were screened negative for endoparasite infestation and next subjected to a microbiological and cultural examination. Hi Enterobacteriaceae Identification kit (KB003) was used for identification following bacteriological culture and isolation. 34 of the 45 faecal samples were positive for a single isolate, meaning that 26 (57.77%) of the samples contained Escherichia coli and 8 (17.78%) had Salmonella spp. The other 11 (24.44%) faecal samples tested positive for a mixed Salmonella spp. and E. Coli infection. The research concludes that the most often isolated causal bacteria for calf diarrhea were E. Coli following Salmonella spp.
