Mating experiments have shown that high-level resistance (minimal inhibitory concentration greater than 2,000 microgram/ml) to streptomycin and kanamycin, and resistance to penicillin-streptomycin and penicillin-kanamycin synergism are transferable by conjugation from resistant clinical isolates of enterococci to a sensitive recipient strain. Cesium chloride-ethidium bromide ultracentrifugation...
OBJECTIVE To determine whether the presence of in vitro penicillin-resistant Streptococcus pneumoniae increases the risk of clinical failure in children hospitalised with severe pneumonia and treated with penicillin/ampicillin. DESIGN Multicentre, prospective, observational study. SETTING 12 tertiary-care centres in three countries in Latin America. PATIENTS 240 children aged 3-59 months,...
The purpose of this study was to investigate the in-vitro bacteriostatic activity of levofloxacin in comparison with that of ofloxacin, sparfloxacin and ciprofloxacin against 205 strains of Streptococcus pneumoniae (101 penicillin-susceptible, 51 penicillin-intermediate and 53 penicillin-resistant). The isolates were provided between September 1996 and October 1996 by French hospitals participa...
The clinical and molecular epidemiology of penicillin-resistant Streptococcus pneumoniae and the diagnostic accuracy of a six-primer PCR assay in identifying penicillin resistance were analyzed by using clinical isolates recovered over a 10-year period in middle Tennessee. The prevalence of non-penicillin-susceptible S. pneumoniae isolates (MIC, > or =0.1 microg/ml) increased from 10% in 1990 t...
