A. Zanchi et al., ANTIBIOTIC SUSCEPTIBILITY OF 206 HAEMOPHILUS-INFLUENZAE ISOLATES COLLECTED FROM CHILDREN IN CENTRAL ITALY, European journal of epidemiology, 10(6), 1994, pp. 699-702
Susceptibility of 206 H. influenzae isolates was evaluated by disk dif
fusion method for 11 antimicrobial agents. No isolates were found to b
e resistant to third-generation cephalosporins, amoxicillin+clavulanic
acid, gentamicin and ciprofloxacin. Four untypable isolates (1.9%) we
re beta-lactamase producing ampicillin-resistant; one of these was als
o resistant to chloramphenicol. The rate of resistance against rifampi
n was 0.5 percent.
