An audit to assess the appropriateness of catheter urine culture requests was carried out for a period of one month. The requests were followed up by members of the Infection Control Team at ward level. The laboratory report had no impact on the removal of the catheter in asymptomatic or symptomatic patients, although the reports did aid antibiotic prescribing in symptomatic patients.

Ro 23-6240 is a new difluorinated quinolone antimicrobial agent. Its in vitro activity against a wide range of bacteria was compared with those of other quinolones and beta-lactams. Generally, members of the family Enterobacteriaceae were inhibited by low concentrations of Ro 23-6240 (MIC90 [MIC for 90% of isolates tested], less than or equal to 1 microgram/ml). Ninety percent of Staphylococcus aureus (including methicillin-resistant strains) and Neisseria gonorrhoeae isolates were inhibited by 0.5 microgram/ml. Pseudomonas aeruginosa (MIC90, 2 micrograms/ml) and Bacteroides fragilis (MIC90, 4 micrograms/ml) showed intermediate susceptibility, and Streptococcus pneumoniae (MIC90, 8 micrograms/ml) was less susceptible. Strains resistant to nalidixic acid were less susceptible to all the quinolones tested. The protein binding of Ro 23-6240 (5 micrograms/ml) was 27%.
