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.

Abortion is one of the most important causes of economic losses in sheep livestock and, for this reason, it is very important to know, at an early stage, which pathogens caused abortion.
Aim: The aim of the study is to obtain data about the distribution of abortifacient pathogens in the Italian regions of Latium and Tuscany, the awareness of the distribution of infectious agents causing abortion could allow the development of an appropriate vaccination and prophylaxis plan, to avoid major economic losses.
