WebIntroduction. Colistin is considered one of the last-resort treatments against human infections caused by multidrug-resistant Gram-negative bacteria. 1 The first plasmid-mediated colistin resistance gene mcr-1 was identified on an IncI2 plasmid from Escherichia coli and Klebsiella pneumoniae in China. 2 While mcr-1 remains the predominant plasmid … WebPresumably with the selective pressure exerted from extensive use of broad-spectrum antibiotics, a number of mutations in the plasmid-carried TEM and SHV enzymes have …

WebThe acquisition of genes encoding for extended-spectrum β-lactamases (ESBL) and carbapenemases is the main mechanism of resistance to 3GC and carbapenems, respectively. Several studies have identified the main β-lactamases responsible for epidemics in many countries namely TEM, SHV, and CTX-M for ESBL-producing bacteria, … WebOct 20, 2024 · The high level of resistance to β-lactam and non-β-lactam antibiotics as well as the trend to a MDR profile associated with the blaCTX-M genes are alarming and … rbc and haemoglobin
