... faecalis , and 70 Staphylococcus aureus isolates and compared to that of nalidixic acid, gentamicin and various β -lactam compounds. Moreover, the rate of spontaneous mutants resistant to quinolone compounds was evaluated. In concentrations only insignificantly exceeding the minimal inhibitory...

...Walter H. Traub Spontaneous and selected variants of Serratia marcescens with resistance against chloramphenicol, cotrimoxazole, nalidixic acid, and pipemidic acid, revealed moderately reduced susceptibility for enoxacin and norfloxacin, and slightly diminished susceptibility for ciprofloxacin...

...Walter H. Traub Minimal bactericidal concentrations of trimethoprim, nalidixic acid, and nitrofurantoin revealed effective intraphagolysosomal bactericidal activity against several assay strains of Serratia marcescens as determined with phenylbutazone-treated (2 mg/ml) fresh defibrinated human...

... bacterial DNA gyrase inhibitors (ciprofloxacin, enoxacin, norfloxacin, nalidixic acid and pipemidic acid) revealed intraphagocytic bactericidal activity against ingested S. marcescens bacteria of three test strains; the extent of intraphagocytic activity of these drugs approximated that of rifampin...

...Walter H. Traub; Paula I. Fukushima Several clinical isolates and O-antigen reference strains of Serratia marcescens were shown to yield spontaneously phenotypic variants with nonspecific, combined resistance or decreased susceptibility for chloramphenicol, nalidixic acid, nitrofurantoin...

...D. Greenwood; F. O’Grady The response of Escherichia coli to nalidixic acid was investigated by continuous turbidimetric monitoring of cultures exposed to the drug. Two distinct types of turbidimetric response were detected when dense populations of E. coli were exposed to nalidixic acid...

...Walter H. Traub; Ingrid Kleber Combined resistance against chloramphenicol (CHLOR), nalidixic acid (NA), and trimethoprim (TMP) was demonstrated in isolates and variants of a nosocomially significant, multiple-drug-resistant, nonconjugative strain of Serratia marcescens (bacteriocin type 18...
