Transthoracic needle aspiration of the lung in guinea pigs with experimental pseudomonas pneumonia was evaluated. The number of bacteria in aspirates correlated well with that of bacteria in the lungs which showed diffuse pneumonia (10(7) inoculum group). The number of deaths of experimental animals increased together with an increase of the times of(More)
The antimicrobial activity of ofloxacin was tested against 15 standard strains and 37 clinical and environmental strains of Legionella pneumophila by agar dilution susceptibility studies with a new growth medium. The ofloxacin MICs were inoculum dependent and ranged from 0.03 to 0.125 microgram/ml. The antibacterial activities of other agents tested(More)
The clinical efficacy, safety and usefulness of Cefepime (CFPM), a new cephem antibiotics, in chronic respiratory infections were evaluated in a comparative study against Ceftazidime (CAZ). Each drug was administered by intravenous drip infusion at a dose of 1.0 g (nominal potency), twice daily for 14 days, and the following results were obtained: 1. A(More)

The clinical significance of Branhamella catarrhalis in respiratory infections is evaluated. 175 strains were isolated, mainly from the sputum, in 71 patients with respiratory infections. B. catarrhalis was most frequently isolated in mixed infections with Haemophilus influenzae (38.3%), H. influenzae plus Streptococcus pneumoniae (10.3%) or S. pneumoniae(More)
The antimicrobial activity of ciprofloxacin was tested against 15 standard reference strains, and 37 clinical and environmental strains of Legionella pneumophila by an agar dilution method, using a new growth medium (B-SYE agar) which we devised. The minimal inhibitory concentrations of ciprofloxacin were found to be inoculum dependent, and ranged from 0.02(More)
