Aim: This study aimed at determining the serotypes, antimicrobial profiles, and public health importance of Salmonella strains from camels slaughtered at Maiduguri central abattoir, Nigeria.

Materials and Methods: Two hundred samples were obtained from camel comprising of intestines, feces, liver, and spleen (n=50 each). Non-lactose fermenting dark center Salmonella colonies were identified using standard biochemical techniques, serotyped and subjected to antimicrobial susceptibility test using minimum inhibition concentration method.

Results: Out of the 200 samples collected, 17 were Salmonella positive (spleen=7, intestine=6, feces=3, and liver=1) with a prevalence of 8.5%. Five serotypes comprising Salmonella Eko, 7 (3.5%), Salmonella Uganda, 4 (2.0%), Salmonella Amager, 2 (1.0%), SalmonellaWesthampton, 2 (1.0%), and Salmonella Give, 2 (1.0%) were incriminated. Majority of the serotypes were sensitive to the antimicrobials, but one Salmonella Amager exhibited resistance to streptomycin, and one each of Salmonella Uganda and Salmonella Eko were resistant to sulfamethoxazole.

Conclusion: This study revealed the prevalence and the antibiotic resistance profile of newly emerging Salmonella from camels in the northeast of Nigeria, which can serve as a means for the transmission of Salmonella to human. Therefore, there is a need for the establishment of national Salmonella surveillance and control programs.
