Pasteurella is a genus of bacteria that includes several species, most commonly Pasteurella multocida. Here are some general characteristics of the genus Pasteurella:

1. Gram-negative: Pasteurella bacteria are known for being gram-negative, which means they do not retain the crystal violet stain during Gram staining.

2. Facultative anaerobes: Pasteurella bacteria can metabolize both with and without oxygen. They can thrive in environments with or without oxygen.

3. Catalase-positive: Pasteurella bacteria produce the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen.

4. Non-motile: Most species of Pasteurella are non-motile, meaning they do not have flagella for movement.

5. Non-spore-forming: Pasteurella bacteria do not form spores, which are dormant structures that allow bacterial survival in harsh conditions.

6. Fastidious: Pasteurella bacteria have complex nutritional requirements and may require specific nutrients or growth factors for optimal growth.

7. Can cause animal diseases: Many species of Pasteurella are normal inhabitants of the respiratory and gastrointestinal tracts of animals. However, some species, like P. multocida, can cause diseases in both animals and humans, such as respiratory infections, abscesses, and septicemia.

8. Zoonotic potential: Pasteurella infections can be transmitted from animals to humans, usually through bites, scratches, or close contact with infected animals.

9. Commonly found in domestic animals: Pasteurella bacteria are frequently isolated from domestic animals, including cats, dogs, rabbits, cattle, and pigs.

10. Treatment and prevention: Infections caused by Pasteurella can be treated with antibiotics, especially penicillin or beta-lactamase-resistant penicillins. Prevention includes proper animal husbandry, vaccination of domestic animals, and prompt treatment of wounds or infections in both animals and humans.

It is important to note that the characteristics mentioned above are general and may differ slightly among the different species within the genus Pasteurella.
