Background: β-lactamases viz., extended spectrum β-lactamase (ESBL), AmpC, and metallo
β-lactamase (MBL) production in Klebsiella pneumoniae has led to a serious concern about …

A worldwide increase in the gastrointestinal colonization by extended-spectrum β-lactamase
(ESBL)-producing bacteria has been observed. Their prevalence amongst Healthy People …

Objectives: To document the prevalence of multi drug resistant gram negative bacilli isolated
from urine of patients attending the Urology Department of Tertiary care Hospital of western …

Background: Production of β-lactamase enzymes by Gram-negative bacteria is the most
common mechanism to acquire drug resistance to β-lactam antibiotics. Limitations in …

Background: Acinetobacter baumannii is an important cause of health care associated
infections which are difficult to control and treat, because of widespread antimicrobial …

Background: The increasing reports on multidrug resistant Escherichia coli has become a
potential threat to global health. Here, we present a cross-sectional study to characterize …

Enterobacteriaceae produces AmpC β-lactamases that make them resistant to commonly
used antibiotics. AmpC β-lactamases can be chromosomal-mediated or plasmid-mediated …

Therapeutic options for infections caused by gram-negative organisms expressing plasmid-
mediated AmpC β-lactamases are limited because these organisms are usually resistant to …

ABSTRACT Purpose The incidence of Extended Spectrum β–Lactamase (ESBL) producing
strains among clinical Klebsiella species and Escherichia coli isolates has been steadily …

The production of extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases is the
most common explanation of multidrug resistance in clinical isolates of Klebsiella spp. In the …
