title: Increased ampicillin resistance in Haemophilus influenzae in Northern Ireland hospitals.
abstract: Twenty-nine of one hundred and ninety-three (15%) clinical isolates of Haemophilus influenzae from Northern Ireland hospitals during 1985-1986 were found to be ampicillin resistant. This is twice the national average for the same period and 65% increase since a similar report in Northern Ireland three years previously. Computerised monitoring of routine specimens has shown this resistance level to be maintained in 1989. Susceptibility to other antimicrobials is discussed.
