20 In vitro activities of modithromycin against Gram-positive and -negative respiratory 21 pathogens including macrolide-resistant cocci with different resistant-mechanisms were 22 compared with those of other macrolide and ketolide agents. MICs were determined by broth 23 microdilution method. All 595 test strains used in this study were isolated from Japanese 24 medical facilities. The erm (r...
There is little information about invasive infections by group B streptococci (GBS) and their antimicrobial susceptibilities in Latin America. We performed a prospective multicenter study to determine the serotype distribution and the antimicrobial susceptibility of GBS in Argentina. We identified 58 cases, but only 44 had sufficient data to be evaluated. Eight early-, four late-, and one fatal...
PROTEKT (Prospective Resistant Organism Tracking and Epidemiology for the Ketolide Telithromycin) is a global surveillance study established in 1999 to monitor antibacterial resistance of respiratory tract organisms. Thirteen centers from Argentina, Brazil and Mexico participated during 1999-2000; they collected 1806 isolates (Streptococcus pneumoniae 518, Haemophilus influenzae 520, Moraxella ...
Abstract Background Streptococcus agalacticae (Group B , GBS) is one of the most important causative agents serious infections among neonates. This study was carried out to identify antibiotic resistance and virulence genes associated with GBS isolated from pregnant women. Methods A total 43 isolates were obtained 420 vaginal samples collected HIV positive negative women who 13–35 weeks attendi...
The effect of certain carcinogens on DNA replication in the intact animal was studied for the determination of whether repair replication was induced and whether there was a change in the rate of de novo replication. Carcino gens were selected to include those known to react with DNA and those for which there was apparently no pre vious evidence for reaction with DNA in vivo. The method used de...
BACKGROUND Group B Streptococcus (GBS) is a cause of neonatal sepsis, pneumonia, and meningitis that can lead to neurological sequelae in infants less than 3 months of age. The GBS disease burden is not known in China, therefore it cannot receive major attention. The main objectives of this study are the evaluation of the incidence of neonatal GBS infection, GBS case-fatality ratio, its serotyp...
disc testing was used to determine antibiotic susceptibility and erythromycin resistance phenotypes. DNA from test samples was prepared by both Qiagen extraction and rapid boiling. As the efficiencies of the two methods were comparable, the rapid boiling method was used throughout. Primers were as published for erm(A), erm(B), erm(C), mef(A/E) 5 and erm(TR). 4 Donor and acceptor probe-pairs wer...
