Sero‐prevalence and risk factors associated with brucellosis in dairy cattle of Sylhet District, Bangladesh: A cross‐sectional study

Abstract

Background:Brucellosis is an emerging disease that causes a significant impact on productive and reproductive performance in dairy cattle. Though Brucella is a pivotal microorganism for dairy cattle, the scenario of brucellosis in Sylhet District is unknown. Objectives:A cross-sectional study was carried out to assess the prevalence and determinants associated with brucellosis in dairy cattle of Sylhet District.Methods: A total of 386 sera and data on determinants from 63 dairy herds were collected from 12 sub-districts using simple random sampling. The sera were tested with Rose Bengal Brucella antigen test, Brucella abortus plate agglutination test and serum agglutination test to find out the sero-positivity.Results: Overall, 17.09% (95% CI: 13.67-21.18) prevalence in cows were calculated.Relatively higher prevalence (56.08%; 95% CI: 42.23-70.32) was recorded in cows having parity ≥4 and were at higher risk (OR = 7.28) than the other cows with parity 0-3.

Addressing Emerging Zoonotic Diseases through a One Health Approach: Challenges Opportunities

“…Brucellosis, a zoonotic bacterial disease, has been neglected in scientific and public health initiatives. An etiology of this condition can be attributed to a distinct strain of bacteria characterized by gram-negative properties, facultative intracellular behavior, absence of spore formation, lack of motility, and absence of a capsule (Ameen et al 2023;Deb Nath et al 2023). Various species of Brucella can cause brucellosis; Brucella abortus is the predominant cause of infection in animals; B. melitensis is the most frequently observed pathogen in humans; B.…”
