Abstract

Brucellosis remains a significant zoonotic disease affecting livestock productivity and public health in India. This study presents a seven-year retrospective surveillance of brucellosis in an organized dairy herd in Uttarakhand, correlating the disease burden with reproductive outcomes and vaccination coverage. Serological testing (ELISA, RBPT, STT), abortion records, and calfhood vaccination data from 2018 to 2024 were analyzed. The findings indicate fluctuations in disease prevalence, with notable peaks in 2022, and reveal a negative association between calfhood vaccination and abortion incidence. The study underscores the need for consistent vaccination and robust monitoring to achieve effective brucellosis prevention.
