Abstract excerpt
Three closely related Klebsiella pneumoniae strains isolated from the same patient harboured bla(CTX-M-15), bla(OXA-1), bla(SHV-11), qnrS1, aac(6')-Ib-cr, oqxAB, aac(3)-II and aph(3')-Ia genes. Two of the isolates were recovered after treatment with meropenem and showed resistance to carbapenems. Sequencing of ompK35 and ompK36 porin genes of the carbapenem-resistant strains revealed the presence of premature...
