Purpose: The aim of this study is to characterize the molecular support of antibiotic resistance in MDR Klebsiella pneumoniae recovered from inanimate surfaces between March 2012 to February 2014 in three teaching hospitals (Setif, Bejaia and Constantine) in Algeria. Results: Forty-four K. pneumoniae producing ESBL were detected and bla(CTX-M-15) and bla(CTX-M-3) were detected respectively in 41 and 3 isolates. These K. pneumoniae isolates producing ESBL were also resistant to gentamicin (87%), tobramicin (87%), ciprofloxacin (66%) and ofloxacin (62%). Aminoglycosides resistance genes detected were 16S rRNA methylase (armA), aminoglycoside acetyl-transferase (aac(6')-Ib), aminoglycoside nucleotidyl-transferase (aadA2) and aminoglycoside, phosphoryl-transferase (ant''Ih-aac(6')-IId). Plasmid-mediated quinolone resistance (PMQR) genes detected were aac(6')-Ib-cr (34 isolates) and qnrB genes in (34 isolates). Multilocus sequence typing (MLST) resulted in 12 different sequence types (STs) regrouped into 5 clonal complexes (CC147, CC17, CC37, CC2 and CC23), one clonal group (CG485) and 4 singletons (ST1426, ST405, ST1308, ST873). Conclusion: Here, we report the detection of the ESBLs encoding gene linked with plasmid-mediated quinolone resistance (PMQR) and aminoglycosides resistance recovered from inanimate surfaces in hospital environment.
