This publication is available in a PDF file format only.

Bacillus spp. are environmental, Gram-positive, endospore-forming pathogens that can cause mastitis. Bacillus spp. will grow large, slightly gray colonies with irregular edges that are often surrounded by a clear zone of hemolysis when grown on blood agar. Some Bacillus spp. can cause acute and potentially fatal gangrenous mastitis. Spores from Bacillus are heat- and chemical-resistant.
