Abstract β-lactamases represent the most common mechanism of β-lactam resistance.
Extended spectrum β-lactamases (ESBLs) represent a major group of β-lactamses currently …

Purpose. Resistant Gram-negative bacterial (GNB) infections, apart from tremendously
escalating the cost of treatment, are a cause for substantial morbidity and mortality among …

Background: Resistance to third generation cephalosporins by acquisition and expression of
extended spectrum beta lactamase (ESBL) enzymes among gram-negative bacilli is on a …

ESBL producers have continued to draw increasing attention globally with their attendant
problems of clinical failure to new generation antibiotics and nosocomial spread. In Nigeria …

Objective To determine the prevalence of extended spectrum beta-lactamase among
Enterobacteriaceae isolated from blood culture in a tertiary care hospital. Methods We …

Background and Objectives. Extended spectrum β‐lactamase (ESBL) production is
increasing all over the world, and organisms other than E. coli and K. pneumoniae are …

Extended spectrum beta-lactmase (ESBL) producing organisms create a major problem for
clinical therapeutics. The frequency of ESBL producing strains among clinical isolates has …

Extended-spectrum beta-lactamase (ESBL) production by Enterobacteriaceae is an
emerging problem. This 3-year prospective study was undertaken to determine the …

ABSTRACT Background and Objectives: The resistance to broad spectrum β-lactams which
is mediated by the extended spectrum beta lactamase (ESBL) enzyme is an increasing …

Methods: One hundred consecutive, non-duplicate clinical isolates of K. pneumoniae
collected over a period of one year (June 2008-June 2009) were included in the study. An …
