The prevalence of small ruminant lentivirus (SRL) infection was evaluated in goats and sheep in two counties of Pernambuco State, Brasil. Seriological examinations were performed from a total of 672 goats and 325 sheep, one year of age and older, at two abattoirs. Sera were analyzed by agar gel immunodiffusion using Maedi-Visna K-1514 antigens. There were 42 reactive samples (95% confidence interval 3.6% to 4.9%) in both slaughter houses. In São Lourenço da Mata county, 3.2% and 4.0% of goat and sheep sera were responsive, whereas in Paulista county, 5.1% of goat samples and 8.2% of sheep were reactive. Thus, the prevalence of small ruminant lentivirus was low in goats and sheep sampled from the region. |

The prevalence of antibodies against bluetongue virus was investigated in 41 dairy goats and 40 sheep herds in the semi-arid region of Pernambuco state and the conditions for insect Culicoides maintenance, considering climate dynamics and vector competence, were evaluated. The percents of seropositive herds in agar gel immunodiffusion test for bluetongue virus group were 24 for goats and 27.5 for sheep. The estimated prevalences of seropositive animals were 3.9% for goats (n = 410) and 4.3% for sheep (n = 400). The prevalences of seropositive animals were low in the mesoregion of Sertão Pernambucano (4.8% for goats and 4.1% for sheep) and São Francisco Pernambucano (1.0% for goats and 4.5% for sheep). There were no significant differences between species... |
