In this paper, it is shown an epidemiological survey of Anaplasma sp. in sheep from three micro-regions (Sertão, Zona da Mata and Agreste) of Alagoas, Northeast of Brazil, by enzyme linked immunosorbent assay - ELISA with recombinant major surface protein - MSP5 of Anaplasma marginale. The frequency of seropositive sheep was 8.92% (20/224). Among regions, frequencies were: Sertão - 6.89% (2/29), Zona da Mata – 10.46% (18/172), and Agreste – 0% (0/23). Differences in the frequencies of seropositive sheep were not statistically significant. However, the lower frequencies were detected in the semi-arid micro-regions (Sertão and Agreste), possibly, due to the unsuitable climatic conditions for the development of tick vectors. These findings point to the need of further studies, to elucidate epidemiological and economic aspects of sheep anaplasmosis in the region.  aAnaplasma marginale  aAnaplasmose  aELISA  aEpidemiologia  aOvino  aSanidade animal  aAlagoas  aBrasil  aMSP5  aProteína recombinante1 aARAUJO, F.
