Nitric oxide and lysozyme production as an impact to Clostridium perfringens mastitis.

The anaerobic mastitis incidence was used to study the bovine udder response in anaerobic bacterial mastitis caused by the Gram-positive bacterial strain of Clostridium perfringens. Milk samples positive for C. perfringens were assayed for NO and lysozyme. The model produced a strong NO and lysozyme response which correlated positively with the severity and outcome of the disease (subclinical and clinical stages). This study is, to our knowledge, the first to suggest a possible link between NO and lysozyme and bovine mastitis caused by C. perfringens. The results raise the possibility that interfering with NO production during mastitis may help to prevent tissue damage.
