|Abstract:||Salmonella is an important intestinal pathogen in horses capable of infecting populations with or without demonstrating clinical illness. In present investigation, one hundred sixty horses, divided in two groups; in first group one hundred ten apparently healthy horses and in second group fifty hospitalized horses were screened for prevalence of Enteric Salmonella in apparently healthy and hospitalized horses in Bikaner district of Rajasthan. Three serial faecal samples were collected from one hundred sixty horses and evaluated for the presence of Salmonella by polymerase chain reaction (PCR) using genus-specific oligonucleotide primers. On the basis of PCR test, over all prevalence of Enteric Salmonella was 6.87 per cent, in apparently healthy horses 2.72 per cent and in hospitalized horses 16 per cent. Risk associated factors for Enteric Salmonella were old age, previous antibiotic use, history of diarrhoea, history of colic, history of laminitis and hospitalization. The major risk associated factors for colonization of Enteric Salmonella in hospitalized horses were stress due to long distance transportation before reaching to veterinary hospitals, surgery, antimicrobial treatment, history of gastrointestinal diseases and history of laminitis. The clinical signs observed in positive cases of Salmonellosis were fever, diarrhoea, colic, laminitis and debility. The results of this study suggest that the prevalence of Enteric Salmonella in Bikaner district of Rajasthan is low. Veterinary hospitals are at high risk of Enteric Salmonella infection in horses and hospitalized horses have an increased chance of acquiring and shedding Salmonella organism.|
