Is Pasteurella contagious to humans?
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.
What kind of bacteria is Pasteurella?
Pasteurella are small gram-negative coccobacilli that are primarily commensals or pathogens of animals. However, these organisms can cause a variety of infections in humans, usually as a result of cat scratches, or cat or dog bites or licks.
What are the symptoms of Pasteurella in humans?
Respiratory disease caused by Pasteurella multocida follows a relatively nonspecific course, with cough fever, shortness of breath, and chest pain being common complaints. Pneumonia is the most common type of infection, although tracheobronchitis, empyema, and lung abscesses may also occur.
What is Pasteurella in animals?
Pasteurella species most commonly cause skin and soft tissue infections following an animal bite or scratch, typically from a cat or dog. Pain, tenderness, swelling, and erythema often develop and progress rapidly. Localized lymphadenopathy and lymphangitis are common.
How is Pasteurella treated?
In most cases, children are treated with oral amoxicillin clavulanate because the exact cause of the cellulitis may not be known. If a culture shows the infection is caused by Pasteurella, oral penicillin can be used. Most infections require a 7- to 10-day dose of antibacterials, occasionally longer.
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.
How is Pasteurella treated in cattle?

What kind of infection is known as pasteurellosis?
Until taxonomic revision in 1999, Mannheimia spp. were classified as Pasteurella spp., and infections by organisms now called Mannheimia spp., as well as by organisms now called Pasteurella spp., were designated as pasteurellosis. The term “pasteurellosis” is often still applied to mannheimiosis, although such usage has declined.
When does pasteurellosis occur after a cat bite?
