MOTTA GIRALDO, Javier Leonardo; CLAVIJO HOYOS, José Angel; WALTERO GARCIA, Indira  e  ABELEDO, María Antonia. Seroprevalence of Brucella abortus, Leptospira sp. and Neospora caninum in cattle, buffaloes and mixed farms, in the Department of Caqueta, Colombia. Rev Salud Anim. [online]. 2014, vol.36, n.2, pp. 80-89. ISSN 0253-570X.

In order to determine and compare the prevalence of antibodies to Brucella abortus, Leptospira sp. and Neospora caninum, two cattle, two buffaloes and three mixed (both species) farms, were researched, besides including three buffaloes sale facilities. Antibody prevalence was higher in buffaloes than in cattle for the three studied agents, Leptospira sp. (37,3% vs 28%), Neospora caninum (45.4% vs. 12.5%) and Brucella abortus (11,9% vs. 5,3%). Antibodies were present at six serovars in both, cattle and water buffaloes and seroprevalence values for Hardjo and Grippotyphosa serovars were superior in both species. The prevalence of antibodies to leptospirosis was higher in simple premises in both cattle and buffaloes, and the seroprevalence to brucellosis in cattle of mixed farms was higher when compared with that obtained in simple farms with a prevalence ratio (PR) of 6,8; (CI, 1,58 to 29,6), whereas in buffaloes, the prevalence of antibody was higher in those single (OR, 2,8 , CI = 1,18 to 5,71 ). In cattle, there was not an association between the seroprevalence to Neospora caninum and the herd type, but in buffaloes seroprevalence was higher in simple farms with a RP of 2,3 (CI= 1,75 to 3,01). It is concluded that buffaloes and cattle have a high prevalence of antibodies to Neospora caninum and Leptospira sp. in all herds and sale facilities and there are still herds affected by Brucella abortus in spite of having the control programs established.
