Proteus spp. are uncommon environmental mastitis pathogens that have been known to cause outbreaks. Proteus spp. are Gram-negative and similar in structure to other coliform mastitis pathogens. Little is known about how Proteus spp. infect the mammary gland, however procedures effective in controlling coliform mastitis pathogens should apply to Proteus spp. as well. When grown on blood agar, Proteus spp. have been found to swarm on the plate and spread across it.
