DRAMIŃSKI - Cow mastitis

Contagious mastitis is sometimes referred to as Cow-to-Cow mastitis because it is generally spread from cow to cow. The primary habitat of bacteria causing contagious mastitis is on the udder and in teat lesions. These bacteria have poor survival in the environment when not associated with the skin or in the gland. Contagious mastitis is the type of mastitis in chronic or subclinical mastitis. The infection is transmitted by milk-contaminated fomites at milking, by a sponge used to wash the cow’s teats, by the milker’s hands, and by the milking machine. The major organisms causing contagious mastitis are Streptococcus agalactiae, Staphylococcus aureus, or Mycoplasma.
