Barber and Rozwadowska-Dowzenko (1948) recorded that naturally resistant penicillinase-producing staphylococci found within hospital communities had increased in the previous successive three years from 14% to 38% and then to 59%. Forbes (1949) isolated resistant staphylococci from 23 out of 50 nurses. Martin and Whitehead (1949) examined the nose, throat, saliva, and skin of 50 medical student...

OBJECTIVES Integrons are thought to play an important role in the spread of antibiotic resistance. This study investigates class 1 and 2 integron-positive methicillin-resistant coagulase-negative staphylococci strains isolated in Iran and characterizes their patterns of antimicrobial resistance. METHODS Hundred clinical isolates of coagulase-negative staphylococci were characterized for integ...

patients and methods: all samples sent to the lab were routinely processed according to standard microbiological procedures and the cultures yielding growth of cons were selected for the study. all samples containing cons collected over a 2 year-period, were included irrespective of patients' age and gender. the antibiogram of the organisms was recorded according to clsi guidelines and the rati...

Staphylococci are common causes of healthcare-associated and community-associated infections. However, limited data are available on the prevalence, phenotypes and molecular characteristics of Staphylococci in metro system around the world. 320 surface samples were collected from the Guangzhou metro system to isolate and characterize Staphylococci strains. Of the samples, 75.6% (242/320) were c...

Oritavancin (MIC50/90, 0.03/0.06 to 0.12 μg/ml) had potent activity against linezolid-resistant staphylococci, as well as Enterococcus faecalis and Enterococcus faecium (oritavancin MIC50/90, 0.015/0.12 μg/ml against both species). All linezolid-resistant isolates were inhibited by oritavancin at ≤0.12 μg/ml. These results confirmed the absence of cross-resistance between linezolid and oritavan...
