A sudden increase in the incidence of scrapie in Italy in 1997 was subsequently linked to the use of a potentially infected vaccine against contagious agalactia. The relative risk for the exposed farms ranged between 6 and 40. The aim of this study was to assess the long-term impact of exposure to the potentially scrapie-contaminated vaccine on the Italian classical scrapie epidemic. We carried...

Contagious agalactia (CA) is a serious disease syndrome of sheep and goats that is characterized by mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. Mycoplasma (M.) agalactiae is the main cause of the disease in sheep and goats. The aim of the present study was to detect M. agalactiae in conjunctival, synovial fluid, nasal, ear and milk samples in sheep herds with or witho...

mycoplasma agalactia was cultured in pplo broth medium supplemented with sterilized normal horse serum in fermentor. cultivation process continued at 37 ºc under aerobic conditions and growth was terminated after 26 hours cultured period with 2.2×109 mycoplasma per ml. samples were taken at different stages of growth. culture was inactivated with 0.04 %v/v formaldehyde and the vaccine was adjuv...

Contagious agalactia represents one of the most relevant infectious diseases dairy sheep, with Mycoplasma agalactiae being primary etiological agent. The early, sensitive, and specific identification infected animals, as well development efficient prophylactic tools, remain challenging. Here, we present a comprehensive characterization M. antigens focusing on those shared among different isolat...

Contagious yawning may be a useful measure of social psychological functioning, and thus it is important to evaluate the variables influencing its expression in laboratory settings. Previous research has documented that humans yawn less frequently in crowded environments and when under direct observation, but the impact of social presence on contagious yawning remains unknown. Here we present t...

Contagious agalactia (CA) is a highly infectious disease of goats and sheep, and is a form of Mycoplasmosis,which is usually enzootic. Since Mycoplasma agalactiae (M. agalactiae) is the main cause of this disease ingoats, the aim of this study was to isolate and detect M. agalactiae from semen of goat bucks. Thirty-nine semensamples were collected from goat bulks, and all samples were cultured ...

Mycoplasma capricolum subspecies capricolum (Mcc) is one of the causative agents of contagious agalactia (CA), which is an important disease in sheep and goats in the Mediterranean and Middle East countries. Mycoplasma agalactiae is the classic agent of CA in sheep and goats. Mycoplasma mycoides subspecies Capri (Mmc), Mycoplasma capricolum subspecies capricolum (Mcc), and Mycoplasma putrefacie...
