A Universal Culture Medium for Screening Polymyxin-Resistant Gram-Negative Isolates.
The colistin-containing SuperPolymyxin medium was developed for screening polymyxin-resistant Gram-negative bacteria. It was evaluated with 88 polymyxin-susceptible or polymyxin-resistant cultured Gram-negative isolates. Its sensitivity and specificity of detection were ca. 100%. The SuperPolymyxin medium is the first screening medium that is able to detect intrinsic and acquired polymyxin-resi...
متن کاملTobramycin, amikacin, sissomicin, and gentamicin resistant Gram-negative rods.
Sensitivities to gentamicin, sissomicin, tobramycin, and amikacin were compared in 196 gentamicin-resistant Gram-negative rods and in 212 similar organisms sensitive to gentamicin, mainly isolated from clinical specimens. Amikacin was the aminoglycoside most active against gentamicin-resistant organisms, Pseudomonas aeruginosa, klebsiella spp, Escherichia coli, Proteus spp, Providencia spp, and...
متن کاملDetection and Occurrence of Plasmid-Mediated AmpC in Highly Resistant Gram-Negative Rods
OBJECTIVES The aim of this study was to compare the current screening methods and to evaluate confirmation tests for phenotypic plasmidal AmpC (pAmpC) detection. METHODS For this evaluation we used 503 Enterobacteriaceae from 18 Dutch hospitals and 21 isolates previously confirmed to be pAmpC positive. All isolates were divided into three groups: isolates with 1) reduced susceptibility to cef...
متن کاملColistin efficacy in the treatment of multidrug-resistant and extremelydrug-resistant gram-negative bacterial infections.
BACKGROUND/AIM Colistin is used as a salvage therapy for multidrug-resistant and extremely drug-resistant gram-negative bacterial infections. Our aim was to evaluate colistin efficiency and toxicity in the treatment of these resistant gram-negative bacterial infections. MATERIALS AND METHODS This is a retrospective study carried out in a tertiary care hospital during 2011-2013. Study data wer...
متن کاملCHROMagar COL-APSE: a selective bacterial culture medium for the isolation and differentiation of colistin-resistant Gram-negative pathogens.
PURPOSE A selective chromogenic culture medium for the laboratory isolation and differentiation of colistin resistant Acinetobacter, Pseudomonas, Stenotrophomonas and Enterobacteriaceae spp. (CHROMagar COL-APSE) was developed, evaluated and compared to an existing selective bacterial culture medium (SuperPolymyxin). METHODOLOGY The medium was challenged with 84 isolates, including polymyxin B...
