Pasteurella bacteria are Gram-negative bacteria. Some members of the Pasteurellaceae family are important pathogens such as Haemophilus influenzae and others are harmless commensals and live in the gut of humans and other mammals. Information on the biology of these organisms has grown in recent years, due mainly to genetic and molecular studies. The family consists of thirteen genera. Many members of the Pasteurellaceae are used as models of bacterial pathogenesis and host-pathogen-interactions.
