Profile of Enterobacteria Resistant to Beta-Lactams [PDF]

Antibiotics, 2020
A serious emerging problem worldwide is increased antimicrobial resistance. Acquisition of coding genes for evasion methods of antimicrobial drug mechanisms characterizes acquired resistance. This phenomenon has been observed in Enterobacteriaceae family.

Resistance to beta-lactams in Mycobacterium fortuitum [PDF]

Antimicrobial Agents and Chemotherapy, 1992
It is widely assumed that the high level of intrinsic resistance to beta-lactam antibiotics exhibited by mycobacteria results from the combination of factors including permeability to the drugs, beta-lactamase production, and affinity for penicillin-binding proteins (PBPs).

Broad-spectrum β-lactamases among Enterobacteriaceae of animal origin: molecular aspects, mobility and impact on public health [PDF]

, 2010
Broad-spectrum β-lactamase genes (coding for extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases) have been frequently demonstrated in the microbiota of food-producing animals. This may pose a human health hazard since these genes may be present

A degenerate PCR-based strategy as a means of identifying homologues of aminoglycoside and ß-lactam resistance genes in the gut microbiota [PDF]

, 2014
peer-reviewedBackground: The potential for the human gut microbiota to serve as a reservoir for antibiotic resistance genes has been the subject of recent discussion. However, this has yet to be investigated using a rapid PCR-based approach.

Resistance to beta-lactam antibiotics in Streptococcus faecium [PDF]

Antimicrobial Agents and Chemotherapy, 1982
Clinical isolates of Streptococcus faecium are characteristically resistant to beta-lactam antibiotics. Two strains, selected for hypersusceptibility to penicillin, were derived from normally resistant isolates treated with novobiocin. These strains were also found to be hypersusceptible to other beta-lactams.

Beta-Lactam-Resistant Enterobacterales Isolated from Landfill Leachates

Pathogens, 2022
Antibiotic resistance is one of the main challenges worldwide due to the high morbidity and mortality caused by infections produced by resistant bacteria. In Colombia, this problem has been studied mainly from the clinical perspective; however, it is scarcely studied in the leachates produced in landfills.

Can we prevent antimicrobial resistance by using antimicrobials better? [PDF]

, 2013
Since their development over 60 years ago, antimicrobials have become an integral part of healthcare practice worldwide. Recently, this has been put in jeopardy by the emergence of widespread antimicrobial resistance, which is one of the major problems ...

Antimicrobials: a global alliance for optimizing their rational use in intra-abdominal infections (AGORA) [PDF]

, 2016
Intra-abdominal infections (IAI) are an important cause of morbidity and are frequently associated with poor prognosis, particularly in high-risk patients.

Escape mutations circumvent a tradeoff between resistance to a beta-lactam and resistance to a beta-lactamase inhibitor

Nature Communications, 2020
Beta-lactamase inhibitors are increasingly used to counteract antibiotic resistance mediated by beta-lactamase enzymes. These inhibitors compete with the beta-lactam antibiotic for the same binding site on the beta-lactamase, thus generating an ...
