Background: In India, milk production is important for both the economy and the provision
of nutritious food. However, the productivity of the livestock is affected by circulating
infectious diseases, and some zoonotic diseases, such as brucellosis, may cause a heavy
impact on the farm as the disease cause abortions and reproductive failures in bovines,
with chronic febrile illness in humans.
Methods: 249 dairy farms in the state of Haryana, India, were interviewed, and collected raw
milk from 81 were analyzed for antibodies towards Brucella abortus.
Results: More samples were positive using milk ring test (MRT) (55.6%, 45/81) than using
enzyme-linked immunosorbent assay (ELISA) (29.6%, 24/81), with all ELISA positive samples also
positive in MRT. The ELISA results were used for risk factor analyses. Seropositive farms were
significantly (p = 0.015) larger than seronegative, with an average 7.9 cattle, compared to 4.9.
Seropositive farms were more likely to report stillbirth occurring the last year, and a significantly
higher proportion of seropositive farms reported retained placenta (odds ratio 5.2).
Conclusion: This study showed that Brucella seroprevalence is high among farms in Haryana,
and a control program is needed to ensure improved human and animal health, as well as
improved livestock productivity.
