Resumen:
Brucellosis, leptospirosis, bovine viral diarrhea (BVD) and infectious
bovine rhinotracheitis (IBR) are abortive diseases that compromise
productive efficiency in cattle. In different municipalities of Oaxaca,
Mexico, reproductive problems suggestive of these diseases have been
observed. This study determined the frequency of BVD, IBR, brucellosis
and leptospirosis in dual-purpose cattle herds in different regions of
Oaxaca, Mexico. A total of 2,691 blood samples were collected from 127
bovine herds to diagnose brucellosis serologically using the Rose Bengal
and Rivanol tests; microscopic agglutination test (MAT) with a battery
of six Leptospira serovars; ELISA by blocking and indirect for BVD and
IBR respectively. The apparent overall frequency of herd was
brucellosis: 2.3%, leptospirosis: 86.6%, IBR: 65.4% and BVD: 56.7%.
The real frequency for brucellosis, leptospirosis, IBR and BVD was
-9.1% (CI95=-10.1, -7.9%), 64.3% (CI95 = 62.5, 66.1%), 40.1% (CI95
= 38.2, 41.9%) and 33.2 % (CI95 = 31.4, 35.0%) respectively. In Costa
region, the highest percentage of animals with antibodies against
Leptospira, IBR and BVD was observed. The present study showed
serologically the presence of antibodies against brucellosis, IBR, BVD
and six serovars of Leptospira in bovine herds' double purpose of Oaxaca
State, Mexico.
