Antimicrobial resistance and serotype distribution of Streptococcus pneumoniae strains isolated in southern Taiwan.

The antimicrobial susceptibilities and serotypes of 115 Streptococcus pneumonia strains isolated in southern Taiwan from January 1990 to December 1993 were determined. All isolates were susceptible to cephalothin, cefotaxime, trimethoprim/sulfamethoxazole and vancomycin, and 14 of the isolates were resistant to penicillin G. The oxacillin disk method for presumptive detection of resistance to penicillin had a sensitivity of 85.7% and specificity of 97.0%. Resistance rates were as follows: erythromycin 62.2%, tetracycline 71.3%, clindamycin 46.1% and chloramphenicol 19.1%. Eighty-four percent o…

Meropenem is a new carbapenem antibiotic that is stable to human renal dehydropeptidase-I (DHP-I) and exhibits potent bactericidal activity … o meropenem. The activity of meropenem against anaerobes is at least as potent as metronidazole and clindamycin. These impressive in vitro data have been the basis for an extensive clinical evaluation programme in many indications including infections caused by single or multiple pathogens.

Genotypic and phenotypic characterization of Helicobacter cinaedi and Helicobacter fennelliae strains isolated from humans and animals.

By DNA-DNA hybridization, we classified 26 human strains, 4 dog and cat strains, and 4 hamster strains putatively identified as Helicobacter … imicrobial susceptibility testing. We found that human strains of H. cinaedi were more resistant to clindamycin and erythromycin than were animal isolates; 19% of the human strains were resistant to ciprofloxacin. Therefore, we recommend that antimicrobial susceptibility results be obtained before initiating therapy for H. cinaedi and H. fennelliae infections …

Optimum treatment of staphylococcal infections.

Serious staphylococcal infections remain a significant clinical problem despite advances in antibacterial therapy. Resistance to penicillin is common and methicillin-resistant staphylococci have become troublesome nosocomial pathogens in many institutions. Penicillinase-resistant penicillins (e.g. flucloxacillin, cloxacillin and oxacillin) are the preferred drugs for all methicillin-susceptible staphylococcal infections, although first generation cephalosporins, beta-lactam/beta-lactamase inhibitor combinations, clindamycin, and occasionally erythromycin and cotrimoxazole (trimethoprim/sulfame…

Downregulation of an NfsA-like nitroreductase causes metronidazole resistance in Gardnerella vaginalis.

OBJECTIVES: The facultatively anaerobic or microaerophilic bacteria of the genus Gardnerella are the most common species associated with bacterial vaginosis (BV). The treatment of BV is greatly complicated by the high rates of resistance to metronidazole and clindamycin among Gardnerella strains. We wanted to identify factors contributing to metronidazole resistance in G. vaginalis and performed high-throughput mass spectrometry on a selection of susceptible and resistant strains. METHODS: We wanted to identify factors contributing to metronidazole resistance in G. vaginalis and performed hig…
