Increasing resistance of Staphylococcus aureus to ciprofloxacin.
نویسندگان
چکیده
We demonstrated the marked emergence of resistance to ciprofloxacin among Staphylococcus arueus strains isolated at the Ann Arbor Veterans Administration Medical Center. All S. aureus isolates tested from 1984 to 1985 were susceptible, whereas 55.1% of methicillin-resistant and 2.5% of methicillin-susceptible strains from 1989 had high-level resistance to ciprofloxacin.

OBJECTIVE We attempted to determine if an increase in resistance to ciprofloxacin occurred among nosocomial pathogens, especially Pseudomonas aeruginosa and Staphylococcus aureus. METHODS We examined 1989-1992 ciprofloxacin susceptibility results from 8,517 P aeruginosa and 9,021 S aureus isolates associated with nosocomial infections reported to the National Nosocomial Infections Surveillanc...

We have studied the nature of ciprofloxacin resistance in methicillin sensitive and resistant Staphylococcus aureus among patients in a tertiary care hospital in Bengaluru, South India. All the isolates were highly resistant to ciprofloxacin. Molecular characterization of these samples performed using Staphylococcal Cassette Chromosome typing and multilocus sequence typing showed that 37.5% of ...

Background: Activity of norA efflux pump is one of the antibiotic resistance mechanisms in ciprofloxacin resistant Staphylococcus aureus. In this study, the effect of Artemisia ciniformis extract on reducing the expression of norA efflux pumps gene in ciprofloxacin-resistant Staphylococcus aureus isolates was studied. Materials and Methods: Ciprofloxacin resistant S. aureus isolates, were trea...
