Soroprevalência da infecção por Brucella ovis em ovinos explorados na microrregião homogênea de Teresina, Piauí, Brasil.

[Brucella ovis infection seroprevalence in sheep exploited the homogeneous micro Teresina, Piaui, Brazil]. Abstract: Considering the importance of this disease and the lack of data on the state of Piauí, the aim of this study was to determine the sero-epidemiological situation of Brucella ovis infection in sheep from Teresina homogeneous microregion, Piauí. The study included a sampling universe of 282 sheep distributed in 24 herds, and the samples were collected by venipuncture of the jugular vein. Serology for detection of anti-B. ovis antibodies was performed by the method of agarose gel immunodiffusion (AGID). Of the 282 samples tested, there was 5.67% (16/282) positive to B. ovis infection by immunodiffusion in agarose gel test. Brucella ovis is present in sheep flocks in Teresina homogeneous microregion, necessitating thus the implementation of control measures to prevent the spread of this disease.Trabalho apresentado nos Anais do VII Congresso Norte Nordeste de Reprodução Anima (CONERA), Mossoró, maio, 2014

Soroprevalência da infecção por Chlamydophila abortus em pequenos ruminantes explorados na Microrregião HOmogênea de Teresina, Piauí, Brasil.

[Seroprevalence of Chlamydophila abortus infection in small ruminants exploited the Teresina homogeneous microregion, Piaui, Brazil]. Abstract: Aimed to conduct epidemiological survey of Chlamydophila abortus in productive and reproductive losses in sheep and goat flocks in homogeneous microregion of Teresina, Piauí, Brazil. 450 samples, 150 sheep and 300 goats were examined. Blood serum samples was stored at -20 ° C and 10 samples from each farm were randomly selected for analysis. The overall prevalence of Chlamydophila abortus in sheep and goats in homogeneous micro region of Teresina was 10.66% (48/450). The overall prevalence of infection by C. abortus in sheep flocks in the region analyzed was 11.3% (17/150) and 7% (21/300) of the overall prevalence of infection in the herd goats. The Chlamydophila abortus agent is present in sheep and goat flocks in homogeneous micro region of Teresina recording the first occurrence of this infection in goats and sheep exploited in the state of Piaui, Brazil.Trabalho apresentado nos Anais do VII Congresso Norte Nordeste de Reprodução Animal (CONERA), Mossoró, maio, 2014
