Pasteurellaceae

Pasteurellaceae is a large family of Gram-negative bacteria. Most members live as symbionts in the respiratory tracts of birds and mammals, especially in the nasopharynx. Many species within the family are pathogenic.

Taxonomy

The family Pasteurellaceae was first proposed in 1981. It contains some of the most well-known bacterial genera, including Pasteurella, Haemophilus, and Actinobacillus.

Characteristics

Members of the Pasteurellaceae are typically small, non-motile, and facultatively anaerobic. They are Gram-negative, meaning they do not retain the crystal violet stain used in the Gram stain procedure.

Pathogenicity

Many species within the Pasteurellaceae are pathogenic, causing diseases in humans and animals. For example, Pasteurella multocida is a common cause of infection in animals and can also infect humans, typically through animal bites.

Treatment

Treatment of infections caused by Pasteurellaceae typically involves antibiotics. However, some species have developed resistance to certain antibiotics, making treatment more challenging.
