Pasteurella multocida (formerly known as Bacillus pyogenes)

Pasteurella multocida is a type of bacteria commonly found in the mouths of animals like cats, dogs, and livestock. It can be transmitted to humans through bites, scratches, or close contact, often causing infections such as skin wounds, cellulitis, or respiratory issues. While it’s normally harmless in animals, in humans, it can lead to serious illnesses if not treated promptly. Proper wound care and hygiene are important after an animal bite. It was formerly called Bacillus pyogenes, but now the correct name is Pasteurella multocida, reflecting its classification.
