R. Johnson, R. C. F. Thompson, H. Humphreys, J. T. Macfarlane] Ampicillin resistance amongst isolates of Haemophilus influenzae is of increasing concern but its clinical impact is unclear. We performed a retrospective study of 34 hospital patients with lower respiratory tract infection (LRTI) caused by β-lactamase positive (β+) H. influenzae and compared these with 34 control patients with LRTI caused by β-lactamase negative (β−) strains. Chronic obstructive pulmonary disease was the most common underlying condition in both groups (β+23/24, β−25/34). A recent course of antibiotics, especially ampicillin/amoxycillin, was significantly (P<0.05) more common in the β+ group (β+ 17/34, β− 3/34). Other pathogens were isolated more frequently in the β+ group (β+ 10/34, β− 4/34). There was no difference in outcome between the two groups. © 1996 by the British Society for Antimicrobial Chemotherapy Brief reports nationallicence Johnson S. R.
