Transmission. Pasteurella spp. are transmitted by animal bites, scratches or licks. Animals do not have to be ill to pass the bacterium to humans, as they can carry the organism without showing symptoms.

How is Pasteurella spread?

Pasteurella infections are spread by inhalation of aerosol droplets, by direct nose to nose contact, or by ingestion of food and water contaminated by nasal and oral discharges from infected animals. Humans can also acquire the organism through dog or cat bites.

Is Pasteurella airborne?

Pathogenicity. Pasteurella multocida is transmitted to humans by contact with infected animals, usually following bites or scratches from cats or dogs. Respiratory tract infections may occur through airborne transmission (see Chapter 73).
