[Comparative bacteriologic activity of norfloxacin, ofloxacin and pefloxacin against 320 Gram-negative bacilli resistant and non-resistant to nalidixic acid and cephalosporins].

Bacteriostatic and bactericidal effects of three fluoroquinolones, norfloxacin, ofloxacin and pefloxacin, against 320 strains of Gram-negative bacilli were studied in vitro. For nalidixic acid-susceptible Enterobacteriaceae, susceptibility or resistance to second or third generation cephalosporins has no significant bearing on the MIC 90 of each of the… CONTINUE READING
