background: multidrug resistance and production of extended spectrum β-lactamases (esbls) by enteric gram-negative rods in hospitals and community continue to be worsened. we aimed to characterize the multidrug resistance and determine the prevalence of esbl production by clinical isolates of enterobacteriaceae in southeast iran. methods: gram-negative bacteria isolated from clinical samples ...
Background and purpose: Production of beta-lactamase enzymes by bacteria, especially Extended-spectrum β-lactamases (ESBLs) is one of the major problems worldwide. ESBLs are mostly located on bacterial plasmids and it is recognized that SHV, TEM, and CTX-M are prevailing among them. The aim of this study was to determine the ability to produce ESBLs genes based on molecular method among non-fer...
BACKGROUND Carbapenems are the last line of defence against ever more prevalent MDR Gram-negative bacteria, but their efficacy is threatened worldwide by bacteria that produce carbapenemase enzymes. The epidemiology of bacteria producing carbapenemases has been described in considerable detail in Europe, North America and Asia; however, little is known about their spread and clinical relevance ...
