Which type of transmission is associated with Pasteurella multocida?

• A. Human-to-human transmission
• B. Dog or cat bite
• C. Contaminated food
• D. Aerosol droplet

Answer: (B)

Pasteurella multocida is primarily associated with infections resulting from bites or scratches from domestic animals, particularly cats and dogs. This bacterium is normally found in the mouths of these animals and can be introduced into human tissue through a bite. When an animal bites a person, it can inject the bacteria directly into the wound, leading to localized infections that may necessitate medical attention. Infections caused by Pasteurella multocida typically present with rapid development of symptoms, often including redness, swelling, and pain around the site of the bite. In severe cases, it can lead to more serious complications such as arthritis or systemic infections, particularly in immunocompromised individuals. Other potential options for transmission, such as human-to-human, contaminated food, or aerosol droplets, are not relevant for Pasteurella multocida. The organism does not spread between humans, nor is it associated with foodborne illness or respiratory spread. The most significant risk factor for infection remains contact with an infected animal, confirming that bites or scratches from pets are the route of transmission for this pathogen.
