Molecular epidemiology of colistin-resistant Pseudomonas aeruginosa producing NDM-1 from hospitalized patients in Iran
Objective(s): Resistance to carbapenems is the principal reason for the continuing utilization of colistin as a last resort choice for treating the infections resulted from multidrug carbapenem-resistant Pseudomonas aeruginosa (CRPA) isolates. The assessment of antimicrobial resistance pattern, the prevalence of carbapenem-resistance determinants, and molecular epidemiology of colistin-resistan...
متن کاملColistin-oxolinic acid blood agar: a selective medium for the isolation of Gardnerella vaginalis.
Colistin-oxolinic acid medium is proposed as a selective isolation medium for Gardnerella vaginalis. The medium is effective in inhibiting staphylococci and gram-negative bacteria while allowing growth of G. vaginalis.
متن کاملNew update on molecular determinants of colistin resistance in bacteria
Colistin relates to the polymyxin group of antibiotics. This antibiotic is still used to destroy gram-negative bacteria as a last resort. However, resistance to this antibiotic has been reported and is appearing day by day. Not much information is available on the exact mechanisms of resistance to this antibiotic. Also, not enough information about pharmacokinetics and pharmacodynamics is avail...
متن کاملColistin heteroresistance in carbapenemase-producing Klebsiella pneumoniae.
Sir, Klebsiella pneumoniae is an important pathogen that causes severe and life-threatening infections. Most isolates demonstrate resistance to various antimicrobial agents. Carbapenems have been widely used to treat serious infections with multidrug-resistant K. pneumoniae. However, the increasing use of these compounds has led to the emergence of carbapenem-resistant isolates via acquired gen...
متن کاملComparison of isolation of Haemophilus vaginalis (Corynebacterium vaginale) from peptone-starch-dextrose agar and Columbia colistin-nalidoxic acid agar.
A total of 447 cervical or vaginal specimens were inoculated in parallel onto peptone-starch-dextrose (PSD) and Columbia colistin (10 mg/ml)-nalidixic acid (15 mug/ml) (CNA) agar and were incubated for 48 h at 35 degrees C in an atmosphere with 2 to 10% CO2. One hundred (22.4%) of the cultures were positive for Haemophilus vaginalis. Forty-eight of the isolates were recovered from both PSD and ...
