| Sumario: |
The relationships between the seroprevalences of Anaplasma rnarginale, Babesia bige mina, Babesia bovis and some selected factors were assessed. Factors studied were age,
breed, herd size, farm size, rotational grazing schedule, grass variety and acaricide usage.
These relationships were analyzed in 39 herds belonging to a Livestock Information Sys tem developed by the School of Veterinary Medicine: 23 dairy farms ( 1352 animals ), eight
cow-calf and eight dual purpose farms (2204 animals) from different ecological areas in
Costa Rica. Using random-effect logistic regression as analytical method, the following
risk factors were found: season (rainy), age (over 1 year) and dipping interval (30 days)
for the seroprevalence ofA. marginale, B. bigemina and B. bovis in the dairy farms. On the
other hand, in beef and dual purpose cattle, breed (Bos taurus), age (over 1 year) and
season (rainy) were detected as risk factors for the seroprevalence of A. marginale and
season (dry), age (less than 1 year) and breed (Bos taurus) for seroprevalence ofbabesiosis. |
