The multidrug resistant Escherichia coli strains causes multiple clinical infections and has become a rising problem
globally. The metallo-ß-lactamases encoding genes are very severe in gram-negative bacteria especially E. coli. This
study was aimed to evaluate the prevalence of MBLs among the clinical isolates of E. coli. A total of 65 E. coli isolates
were collected from various clinical samples of Malaysian patients with bacterial infections. The conventional
microbiological test was performed for isolation and identification of E. coli producing MBLs strains in this vicinity.
Multidrug Resistance (MDR) of E. coli isolates were assessed using disk diffusion test. Phenotypic methods, as well as
genotypic- PCR methods, were performed to detect the presence of metallo-ß-lactamase resistance genes (blaIMP,
blaVIM) in imipenem resistant strains. Out of 65 E. coli isolates, 42 isolates (57.3%) were MDR. The isolates from
urine (19) produced significantly more MDR (10) isolates than other sources. Additionally, 19 (29.2%) imipenemresistant
E. coli isolates contained 10 MBLs gene, 7(36.8%) isolates contained blaIMP and 3(15.7%) isolates contained
blaVIM genes. This study revealed the significant occurrence of MBL producing E. coli isolates in clinical specimens and
its association with health risk factors indicating an alarming situation in Malaysia. It demands an appropriate concern
to avoid failure of treatments and infection control management.
