investigation of plasmid-mediated quinolone resistance among isolates obtained in a turkish intensive care unit.the aim of this study was to search for three plasmid-encoded, quinolone-resistant determinants: qnra, qnrb, and qnrs. thus, 460 gram-negative strains belonging to 11 different genera (clinical, 347; non-clinical, i.e., from a rectal swab, 113), of which 40% were ciprofloxacin-resistant, were recovered from patients in an intensive care unit at the istanbul medical faculty, turkey, in the years 2000 and 2006. pcr with primers specific for qnra, qnrb, and qnrs genes and primers specific for a ser ...200818653977
spread of ndm-1-producing enterobacteriaceae in a neonatal intensive care unit in istanbul, turkey.twenty-two consecutive carbapenem-resistant enterobacterial isolates were recovered from patients hospitalized between january and april 2013 in different units at a university hospital in istanbul, turkey. these were klebsiella pneumoniae isolates producing the carbapenemases oxa-48, ndm-1, and kpc-2, enterobacter cloacae isolates producing ndm-1, and escherichia coli isolates producing oxa-48. most of the oxa-48-producing k. pneumoniae and all the ndm-1-producing e. cloacae were clonally relat ...201424550328
