Molecular Characterization and Analysis of Risk Factors Associated with Brucellosis in Central Indian and Meghalaya Population.

In this study we evaluated the utility of Abortus Melitensis Ovis Suis Brucella PCR (AMOS PCR) for the molecular characterization of Brucella species and analyzed the associated risk factors for brucellosis in Central Indian and Meghalayan population. AMOS PCR was carried out in a total of 160 BSCP-31 PCR-positive DNA samples isolated previously from the blood of Central Indian ( = 90) and Meghalayan cohorts ( = 70). Clinical and associated risk factors recorded earlier were used to establish strain-specific disease outcomes in study cohorts. was found to be the dominant strain in both Central Indian and Meghalayan cohorts (57.7% and 54.28%, respectively) followed by (42.22% and 38.57%). Although rare, brucellosis cases in the Meghalayan population also showed the presence of (7.14%) and (2.85%). Febrile illness was a major clinical risk factor in both study cohorts, while occupational risk factors like exposure to animals and raw milk consumption were major mediating factors for brucellosis in Central Indian cohorts. On the contrary, meat consumption was found to be significant predisposing factor for brucellosis in Meghalaya. Molecular characterization of Brucella species provides important public health data for mitigation, advocacy, and antimicrobial stewardship.
