Enterobacter cloaceae is a bacterium belonging to the group of enterobacteria that cause acute mastitis with severe impairment of general health. It also includes two gram-negative rods, which in our conditions are the most significant causes of enterobacterial mastitis - Escherichia coli, Klebsiella pneumoniae.
Enterobacteria are found naturally in the digestive tract of animals and humans, and therefore they are widely found in bedding, on the skin, etc., from where they enter the udder.
Mastitis can be preceded by diarrhea, eg in the event of a sudden change in feeding, worsened zoohygienic conditions, metabolic disorders, etc. Mastitis caused by enterobacteria is particularly risky for high-yielding dairy cows and dairy cows, which have a reduced ability to close the teat canal.
