Pasteurella multocida meningitis in infancy – (a lick may be as bad as a bite)

Pasteurella multocida is the commonest cause of local infection after an animal bite, but is an unusual cause of meningitis. We report a case of P. multocida meningitis occurring in a 7-week-old infant which was contracted after non-traumatic contact with a household pet, that is, without any animal bite or scratch. The organism may be easily confused with more common Gram-negative pathogens. In this case, it was initially incorrectly diagnosed as Haemophilus influenzae type b (Hib); a possibility which has important implications in the era of routine use of Hib vaccine in infant immunisation programs.
