No. of bitstreams: 1 Wagnner Jose Nascimento Porto.pdf: 485977 bytes, checksum: 38cc1a2dbc36f847dab429353687fd56 (MD5) Previous issue date: 2007-02-09 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / The prevalence of serum antibodies to Babesia bovis, Babesia bigemina and Anaplasma marginale infections were investigated in cattle farming herds from three regions called Sertão, Agreste and Leste of Alagoas State, Brazil. Sera samples from 1,155 cattle raised in 26 farms were evaluated by enzyme immunoassay (indirect ELISA). At the same time a questionnaire survey was conducted in the data were also analyzed. According to the results, 70.22% (811/1155) of the animals were positive for B. Bovis and 77.40% (894/1155) for B. bigemina and 27.45% (317/1155) of the animals were positive for antibodies against A. marginale The seroprevalence showed that the State of Alagoas is considered enzootically unstable for B. bovis and A. marginale enzootically stable for B. bigemina. The prevalence of Babesia sp infection was higher (p<0.05) in beef cattle than for dairy cattle and mixed herds. Regarding the infection by A. marginale, antibodies levels were more elevated in dairy cattle than others kind of rearing, but this difference was not significant. It is concluded that preventive measures should be adopted especially unstable areas. / A prevalência de anticorpos séricos para infecções por Babesia bovis, Babesia bigemina e Anaplasma marginale foram investigados em bovinos das Mesorregiões do Agreste, Leste e Sertão do Estado de Alagoas, Brasil. Amostras de soro de 1155 bovinos provenientes de 26 propriedades foram analisadas pelo ensaio imunoenzimático (ELISA). Os resultados mostraram que 70,22% (811/1155) dos animais foram sororreagentes para B. bovis, 77,40% (894/1155) para B. bigemina e 27,45% (317/1155) foram positivos à infecção por A. marginale, o que evidencia que o Estado de Alagoas pode ser classificado como área de instabilidade enzoótica para B. bovis e A. marginale, e estabilidade enzoótica para B. bigemina. A prevalência da infecção por Babesia sp foi mais alta (p<0,05) em rebanhos de corte do que nos rebanhos leiteiros ou de aptidão mista. Com relação à infecção por Anaplasma marginale houve diferença não significativa. Conclui-se que medidas preventivas devem ser adotadas especialmente nas áreas de instabilidade enzoótica.
