A mastitis is an inflammation of the mammary gland which is almost always due to the effects of infection by bacterial pathogens.
Environmental mastitis are mastitis caused by bacteria that can be found in the cow’s environment. The primary habitat of bacteria causing environmental mastitis is in the environment: feces, soil, bedding or water. The contamination can occur during environmental contact of the teats at milking time or between milkings, or during dry period.
Environment mastitis are often clinical mastitis with a low increase in somatic cell count. They can appear in lactation but also during the drying period.
Main pathogens responsible of environment mastitis are : Strepto- coccus uberis, Streptococcus dysgalactiae, Escherichia coli, Klebsiella spp., Enterobacter spp., Pseudomonas spp.
