Wounds caused by animal bites, especially cats, are commonly infected with Pasteurella multocida or Bartonella henselae. These bacteria are found in the oral flora of cats and may cause infections in humans through bites, scratches, or even licks on broken skin. While Streptobacillus moniliformis can also be found in cats, it is rare and more commonly associated with rodent bites.
