Resumo:
The aim of this study was to determine the frequency of positive herds (foci) and
seropositive animals for bovine brucellosis in the state of Paraíba, Northeast region of
Brazil. Data from the Agency of Agricultural Protection in the state, collected from its 23
microregions, during the January 2008 to July 2009 period, were used. During this period,
11,149 herds were examined and 55,691 cattle sera were submitted to the diagnosis of
brucellosis. For serological diagnosis the Rose Bengal test was used. A herd was
considered focus when presented at least one seropositive animal. Of the herds
investigated, 104 (0.93%) had at least one seropositive animal, and of the animals
examined, 199 (0.36%) were seropositive. There was significant difference (p < 0.001) in
the proportion of seropositivity for females (0.47%) and males (0.04%).
