Pasteurella spp. are contagious pathogens that are seldom reported as a cause of bovine mastitis. Mastitis caused by Pasteurella spp. usually appears as a thick, creamy-yellow, viscous secretion, sometimes with a foul odor. Pasteurella spp. are Gram-negative and similar in structure to other coliform mastitis pathogens. Additionally, when grown on blood agar, Pasteurella spp. have been found to have irregular, rough colonies that produce a musty odor.
