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.

A Case of Epicardial Epidermoid Cyst in a Crested Porcupine.

The crested porcupine () is present in central Italy with an estimated population of 1800 individuals. Despite the local abundance, little data are available on the diseases affecting free-ranging individuals. We describe a case of an epidermoid cyst (EC) in a male adult porcupine found in the municipality of Sovicille, province of Siena (Tuscany).
