An Investigation of Virulence Genes of in Autologous Vaccines Against Sheep Mastitis.

is well known to be the primary causal agent of clinical or subclinical mastitis in dairy sheep. The production of virulence factors allows strains to cause mastitis. In the present study, 96 strains isolated from dairy sheep farms ued for the production of autologous vaccines were tested for enterotoxin and hemolysin genes by PCR.
