Risk factors associated with brucellosis seroprevalence in cattle herds from Xochimilco, Mexico City. Rev Salud Anim. [online]. 2021, vol.43, n.3, e04.  Epub 01-Dez-2021. ISSN 0253-570X.

In order to identify the factors associated with brucellosis infection, a cross-sectional and descriptive study was carried out in dairy cattle herds from Xochimilco, Mexico City, Mexico. Two hundred and seventy Holstein Freisan cows, older than 6 months, were sampled. The presence of antibodies against Brucella abortus was detected by the card agglutination test (Rose Bengal) and the rivanol test. Epidemiological surveys were applied to farmers and/or owners to evaluate the factors associated with brucellosis infection. The results obtained showed a B. abortus prevalence of 31.8 %, with an average of 5,733b positive for brucella. In 80 % of the herds, there was no quarantine and provenance control area for new additions. The lack of removal of excreta (80 %), placenta and other wastes from childbirth (13.33 %) was noted. Only 13.34 % of the producers had the facilities and specific material for the management of cattle, 46.66 % of the herds had cats living with cows, besides sharing travel paths with other herds (46.66 %). It is concluded that there was a low correlation (r=0.4) estimated between the brucellosis seroprevalence and the factors evaluated: the producer worked in a single herd, cattle had contact with dogs, pets having access to food and water sources, as well as the presence of abortions. Therefore, it is advisable to implement a dissemination program based on regulations for the prevention and control of the disease.
