Sero surveillance of human brucellosis and leptospirosis among veterinary personnel in Sikkim, India: A descriptive cross -sectional study

A cross-sectional sero-surveillance study was conducted across the five districts of Sikkim to determine the seroprevalence of Brucella and Leptospira antibodies among veterinary and para-veterinary personnel. Serum samples were tested for Brucella using the Rose Bengal Test, Standard Agglutination Test, and ELISA (IgG/IgM), while Leptospira antibodies were detected using ELISA (IgG/IgM). Brucella seroprevalence was 18.8%, and Leptospira seroprevalence was 20.5%. The findings indicate a considerable level of exposure to both infections in this occupational group, underscoring the need for strengthened surveillance and preventive measures within a One Health framework.
