Бета-лактамази ентеробактерій: загальна характеристика, механізми та регіональні особливості розповсюдження

Annals of Mechnikov's Institute, 2022
The problem of the formation and spread of resistance to β-lactam antibiotics in clinically significant types of microorganisms is extremely important, since β-lactams traditionally form the basis of the treatment of bacterial infections.

Dissemination of IncF plasmids carrying beta-lactamase genes in Gram-negative bacteria from Nigerian hospitals

Journal of Infection in Developing Countries, 2013
Introduction: Production of beta-lactamases is the predominant cause of resistance to beta-lactam antibiotics in Gram-negative bacteria. We investigated the diversity of plasmid-borne beta-lactamase genes and replicon type of the plasmids carrying the ...

Droplet-based digital antibiotic susceptibility screen reveals single-cell clonal heteroresistance in an isogenic bacterial population [PDF]

, 2020
Since antibiotic resistance is a major threat to global health, recent observations that the traditional test of minimum inhibitory concentration (MIC) is not informative enough to guide effective antibiotic treatment are alarming.

Multiparametric determination of genes and their point mutations for identification of beta-lactamases [PDF]

, 2010
More than half of all currently used antibiotics belong to the beta-lactam group, but their clinical effectiveness is severely limited by antibiotic resistance of microorganisms that are the causative agents of infectious diseases. Several mechanisms for

Evaluation of the ESBL-coding plasmids transmissibility in E. coli isolated from ambulatory patient's urina [PDF]

, 2018
Representatives of the Enterobacteriaceae family are the main causative agents of urinary tract infections. Escherichia coli can exhibit resistance to [beta] -lactam antibiotics by synthesizing ESBL (extended spectrum [beta]-lactamases).
