Pasteurella multocida is normally found in the upper respiratory tract of healthy livestock and domestic animal species, including chickens, turkeys, cattle, swine, cats, dogs and rodents.
Where does Pasteurella come from?
The major means of spread of Pasteurella species is from bites or scratches from animals, particularly cats and dogs. Many animal species are known to be colonized with the organism.
How do you get a Pasteurella infection?
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 do humans get Pasteurella?
Pasteurella multocida is the most common cause of infection following a bite or scratch from domestic pets. Exposure can lead to rapidly progressing soft tissue, respiratory, or other serious invasive infections.
What does Pasteurella grow?
Genus description
Pasteurella spp. are small, pleomorphic, nonmotile, non-spore-forming, Gram-negative coccobacilli. P. multocida is facultatively anaerobic, grows well on blood agar, chocolate agar, Mueller-Hinton agar and brain-heart infusion (BHI), but it shows no growth on MacConkey agar.
What does Pasteurella do to humans?
If your child is bitten or scratched by an animal that carries Pasteurella organisms such as Pasteurella multocida, these bacteria can enter the body through the break in the skin. They most often cause a potentially serious infection of the skin called cellulitis.
Do all cats carry Pasteurella?
Pasteurella spp. are part of the normal oral and respiratory tract flora of cats. However, these bacteria are commonly isolated from feline subcutaneous abscesses, pyothorax, respiratory tract diseases or other conditions, usually as a secondary agent.
What is Pasteurella infection?
Pasteurella multocida is a common cause of infection following bites or scratches caused by dogs and (especially) cats. It is rarely reported, however, and apparently often overlooked as a pathogen. The typical clinical manifestation is a rapidly developing cellulitis at the site of injury.
Where does Pasteurella grow?
Pasteurella are small, facultatively anaerobic, fermentative coccobacilli (Fig. 24.4) commonly found as commensals in the oropharynx of healthy animals. Most human infections result from animal contact (e.g., animal bites, scratches, shared food).

Clinical signs include fever, hypersalivation, nasal discharge, and difficult respiration. They are acute and can occur in 1 to 3 days after exposure.
Is pasteurellosis contagious to humans?
As the infection is usually transmitted into humans through animal bites, antibiotics usually treat the infection, but medical attention should be sought if the wound is severely swelling. Pasteurellosis is usually treated with high-dose penicillin if severe.
How is pasteurellosis diagnosed?
The circumstances of diagnosis of human pasteurellosis are reviewed. The diagnosis is usually suspected for animal bite or scratch wounds. Conversely, in other infections the diagnosis is only based on bacteriological data. Phenotypic misidentification of Pasteurellaceae from clinical material is common.

Abscesses in the middle ear (causing balance problems), eyeball (causing blindness) or in bones or major organs or often difficult to treat and may recur, even with surgery. All rabbits carry Pasteurella organisms, but only some rabbits will manifest disease (their immune systems generally keep the organisms in check).
How do you disinfect Pasteurella?
multocida is available, cleaning of hospitals and other public places with hydrogen peroxide as a disinfectant is the most effective and economical way to prevent pasteurellosis.
What is another name for pasteurellosis?
pasteurellosis, any bacterial disease caused by Pasteurella species. The name is sometimes used interchangeably with the so-called shipping fever, a specific type of pasteurellosis (caused by Pasteurella multocida) that commonly attacks cattle under stress, as during shipping.
Can humans get Pasteurella from cats?
Pasteurella is a Gram-negative coccobacillus that causes a wide spectrum of diseases in humans and is commonly transmitted from cat and dog bites. An increasing number of cats and dogs are kept as pets in American households which increases the risk of pet-related infections.
What is pasteurellosis in sheep?
Pasteurellosis is caused by two common bacteria: Bibersteinia trehalosi and Mannheimia haemolytica and typically causes pneumonia and death. young and store lambs are at highest risk of infection however sheep of all ages are at risk.
How do lambs get Pasteurella?
The disease appears to occur most often in animals that have undergone recent stress such as transportation, weaning, change of diet, or commingling with animals from unrelated farms. Bibersteinia trehalosi (formerly Pasteurella trehalosi) causes septicemia in lambs 4–9 mo old (systemic pasteurellosis).
