[occurrence of 16s rrna methylase arma producing enterobacteriaceae in a general hospital in warsaw, poland].resistance to gentamicin, amikacin and kanamycin was screened in 270 clinical isolates of enterobacteriaceae originated from april 19 to may 19, 2010 in a regular hospital in warsaw, poland. most of the isolated bacteria were considered pathogenic. nineteen isolates (7%) were simultaneously resistant to two or three of the tested aminoglycosides. mics of the three aminoglycosides ranged form 128 to 1024 mcg/ml for six isolates. these isolates were suspected to produce 16s rrna methylase. genes e ...201021114012

[enterobacter cloacae--antimicrobial susceptibility of strains isolated from hospitalized patients in 2004-2005].the profiles of resistance of esbl(-) and esbl(+) strains of enterobacter cloacae were analysed and compared. 466 enterobacter cloacae strains isolated from different specimens obtained from patients of big warsaw hospital in 2004-2005 were investigated. by using the several phenotypic methods 33.5% of strains was identified as esbl(+). esbl(+) strains were significantly less susceptible then esbl(-). these two groups differed mostly in susceptibility to aminoglycosides and fluoroquinolones, e.g ...200920120924
