Differentiation of resistance phenotypes among erythromycin-resistant Pneumococci.
Laboratory differentiation of erythromycin resistance phenotypes is poorly standardized for pneumococci. In this study, 85 clinical isolates of erythromycin-resistant (MIC > or = 1 microg/ml) Streptococcus pneumoniae were tested for the resistance phenotype by the erythromycin-clindamycin double-disk test (previously used to determine the macrolide resistance phenotype in Streptococcus pyogenes...
متن کاملResistance mechanisms of multiply resistant pneumococci: antibiotic degradation studies.
Strains of Streptococcus pneumoniae resistant to penicillin have been reported from several countries around the world. Many South African isolates, in addition, exhibit resistance to tetracycline, chloramphenicol, erythromycin, clindamycin, and cotrimoxazole in varying patterns. A qualitative test of the ability of antibiotic-resistant pneumococci to inactivate penicillin, oxacillin, cephaloth...
متن کاملFluoroquinolone and Other Antimicrobial Resistance in Invasive Pneumococci, Hong Kong, 1995–2001
We determined the susceptibilities of 265 invasive isolates of pneumococci obtained during 1995 to 2001 in Hong Kong to 11 antimicrobial agents and their serotypes. Overall, 62.6% isolates were susceptible to penicillin, 20% were intermediately resistant, and 17.4% were resistant. The overall prevalence of levofloxacin resistance (MIC > or = 8 microg/mL) was 3.8% but increased to 15.2% among th...
متن کاملCarbapenem and Fluoroquinolone Resistance in Multidrug Resistant Pseudomonas aeruginosa Isolates from Al-Zahra Hospital, Isfahan, Iran
Introduction: The major resistance mechanisms of Pseudomonas aeruginosa to fluoroquinolones and carbapenems are associated with the mutations in the genes gyrA and oprD encoding type II topoisomerases (DNA gyrase) and OprD porin, respectively. Method: In this cross-sectional study, sixty five clinical samples were collected from patients hospitalized in Al-Zahra Hospital of Isfahan, Iran. Susce...
متن کاملFluoroquinolone Resistance in Penicillin-resistant Streptococcus pneumoniae Clones, Spain
Among 2,882 Streptococcus pneumoniae sent to the Spanish Reference Laboratory during 2002, 75 (2.6%) were ciprofloxacin-resistant. Resistance was associated with older patients (3.9% in adults and 7.2% in patients > or =65 years of age), with isolation from noninvasive sites (4.3% vs. 1.0%), and with penicillin and macrolide resistance. Among 14 low-level resistant (MIC 4-8 microg/mL) strains, ...
