Mastitis is an inflammation of the udder caused by microorganisms that enter the gland through the teat canal. Once inside the gland, these organisms find ideal conditions in which to multiply and, in turn, to damage the lining of the milk ducts, cistern, and alveoli. As a result, the cow’s immune response is triggered, and white blood cells travel to the udder to fight the infection. This results in increased somatic cell counts. The organisms responsible for this infection can be broadly classified into two groups: contagious and environmental.
