Pasteurella

Pasteurella is a genus of Gram-negative bacteria that are part of the family Pasteurellaceae. The genus was named after the French chemist and microbiologist Louis Pasteur, who made significant contributions to the understanding of these bacteria.

Characteristics

Pasteurella species are typically rod-shaped and are known for their ability to cause disease in both humans and animals. They are facultative anaerobes, meaning they can grow in both the presence and absence of oxygen.

Pathogenicity

Pasteurella species are often found in the oral and respiratory tracts of healthy animals, but they can cause disease when they enter the body through a wound or bite. The most common species associated with human infections is Pasteurella multocida, which can cause a range of conditions including skin and soft tissue infections, respiratory tract infections, and systemic infections.

Treatment

Treatment for Pasteurella infections typically involves antibiotics. The bacteria are generally sensitive to a range of antibiotics including penicillin, amoxicillin, and tetracycline. However, resistance to certain antibiotics has been reported, so susceptibility testing is often recommended.

Prevention

Prevention of Pasteurella infections primarily involves avoiding bites and scratches from animals, particularly cats and dogs. Good wound care is also important if an injury does occur.
