Mastitis

Description

Inflammation of the mammary gland, or mastitis, is most commonly caused by infection with microorganisms resulting in high somatic cell counts and pathological tissue changes. The greatest prevalence and economic importance is in dairy cows (often proportional to the standard of dairy practices as well as the intensity of farming). The severity of mastitis is determined by the interplay of factors between the bacteria, the animal host, and the environment.
