The main mastitis-causing organisms are divided into two groups on the basis of their source of infections, namely the organisms (mainly and ) that are transmitted in the dairy from cow to cow, and organisms that mainly originate in the environment in which the cow lives.

Environmental mastitis has become a problem in well-managed herds that have eliminated SAG or minimised STA. The source of these organisms is the environment surrounding the cow. Problems that increase the likelihood of udder infections are over-crowding, poorly designed housing, wet unhygienic bedding, milking wet udders, poor udder preparation prior to milking, teat injuries and milking machine problems.
