Abstract
In this study, we report the serological, bacteriological and whole genome sequencing data of a 6 years study of Brucella abortus in Meghalaya, India. Investigation of 3060 sera samples indicated overall prevalence of 6.4% by Rose Bengal Plate Test and 10.7% by ELISA. Considerably higher prevalence was observed among milk samples (17.5%, n = 362) and in blood samples (37.7%, n = 262) by direct PCR. Clinical samples (n = 94) from late abortion cases yielded 11 B. abortus isolates. Multi-locus sequence typing indicated circulation of single sequence type, ST1. Whole genome sequencing (n = 8) and phylogenomic analysis revealed close clustering of majority of isolates in two clusters alongwith genomes from other countries, indicating global relatedness among B. abortus. Taken together, the results of our study revealed the putative hotspot of infection in the dairy-dominant districts of the state and also calls for concerted One Health based action for prevention and control of this zoonotic disease.
