    ABSTRACT:

    The present study was conducted to investigate in 20 extensive sheep farms for the seroprevalence of Corynebacterium pseudotuberculosis (n=402) and Toxoplasma gondii (n=228). Enzyme-linked immunosorbent assay (ELISA) was used for the detection of antibodies to C. pseudotuberculosis/T. gondii. It was observed that C. pseudotuberculosis showed the highest prevalence in the region (34.07%) with statistically significant presence (p<0.05) in ewes. Antibodies to T. gondii was reported in 14.91% of the animals studied. About C. pseudotuberculosis/T. gondii coinfection the categories of rams showed significant (p<0.05) differences, suggesting that this gender could perpetuate the diseases in the flocks. It was concluded that the knowledge about the diseases in the region under study would facilitate the execution of prophylactic measures, especially against the diseases that pose risks to the public health and cause damages to the producer.
