Abstract

A murine model of bacteremic Haemophilus influenzae type b pneumonia was used to evaluate the therapeutic efficacies of the quinolone antimicrobial agents enoxacin and ofloxacin compared with those of ampicillin and chloramphenicol. Ampicillin-susceptible (AS) and ampicillin-resistant (AR) challenge strains were employed. Treatment with enoxacin or ofloxacin produced intrapulmonary killing of H. influenzae that was superior to that achieved with ampicillin (P less than 0.01 to P less than 0.001 for both AS and AR strains). Ofloxacin and enoxacin also provided killing greater than that with chloramphenicol for the AS strain (P less than 0.01 to P less than 0.001). For the AR strain, ofloxacin provided killing greater than that obtained with chloramphenicol (P less than 0.001). Survival from AS strain pneumonia was 60% in enoxacin-treated and 78% in ofloxacin-treated animals compared with 41% for chloramphenicol-treated and 23% for ampicillin-treated groups. We conclude that enoxacin and ofloxacin may be effective antimicrobial agents in treating either AS or AR strains causing H. influenzae pneumonia.
