Résumé
Brucellosis is an infectious disease caused by In total, 3610 samples (3221 cattle and 389 buffaloes) were subjected to parallel testing using the Rose Bengal plate test and protein G-based enzyme-linked immunosorbent assay, followed by analyses of animal- and farm-level epidemiological datasets to identify the risk factors. The apparent brucellosis prevalence at the animal level was higher in buffaloes (8.2%, 95% confidence interval [CI] = 5.9-11.4) than in cattle (6.1%, 95% CI = 5.3-7.0). In a multivariable logistic model, animals calved 3-5 times (odds ratio [OR] = 2.22, 95% CI = 1.50-3.1, reference [ref]: animals calved <2 times); animals with a history of abortion (OR = 54.73, 95% CI = 33.66-89.02), repeat breeding (OR = 19.46, 95% CI = 11.72-32.25), and placental retention (OR = 13.94, 95% CI = 4.92-39.42, ref: no clinical signs); and dogs on farms (OR = 2.55, 95% CI = 1.48-4.40, ref: absence of dogs); disposal of aborted fetus in open fields (OR = 4.97, 95% CI = 1.93-12.84) and water bodies (OR = 2.22, 95% CI = 1.50-3.1, ref: buried); purchase of animals from other farms (OR = 6.46, 95% CI = 1.01-41.67, ref: government farms); hand milking (OR = 1.98, 95% CI = 1.02-10.0, ref: machine milking); and use of monthly veterinary services (OR = 3.45, 95% CI = 1.28-9.29, ref: weekly services) were considered significant risk factors for brucellosis in organized bovine herds (p < 0.01). The study identified that the animals calved 3-5 times or with a history of abortion/repeat breeding/placental retention, and disposal of aborted fetus in open fields/water bodies as the potential risk factors for bovine brucellosis. These risk factors should be controlled through the implementation of best practices to reduce the brucellosis burden in bovine farms.

The apparent brucellosis prevalence at the animal level was higher in buffaloes (8.2%, 95% confidence interval [CI] = 5.9-11.4) than in cattle (6.1%, 95% CI = 5.3-7.0).

Conclusion
UNASSIGNED
The study identified that the animals calved 3-5 times or with a history of abortion/repeat breeding/placental retention, and disposal of aborted fetus in open fields/water bodies as the potential risk factors for bovine brucellosis. These risk factors should be controlled through the implementation of best practices to reduce the brucellosis burden in bovine farms.
