Beta-Lactam Resistance

Revista de Gestão Social e Ambiental
Objective: Investigate beta-lactam resistance in order to identify the associated factors, the main beta-lactam resistant microorganisms and their complications.   Theoretical Framework: Beta-lactam resistance is a worldwide health problem, consisting of the inability to respond to the action of antibiotics.

The Relationship between Antimicrobial Use and Antimicrobial Resistance in Europe

Emerging Infectious Diseases, 2002
In Europe, antimicrobial resistance has been monitored since 1998 by the European Antimicrobial Resistance Surveillance System (EARSS). We examined the relationship between penicillin nonsusceptibility of invasive isolates of Streptococcus pneumoniae (an

Mechanism of resistance to beta-lactam antibiotics

BULLETIN of the L.N. Gumilyov Eurasian National University. BIOSCIENCE Series, 2023
Acinetobacter baumannii is the most commonly associated human pathogen with infections in the genus. This opportunistic pathogen causes quite serious infections, especially in fond patients, and has the ability to quickly develop resistance to new antibiotics. In the recent past, carbapenems, a.

ftsI mutations versus beta-lactamase (blaTEM) production in beta-lactam resistance of Haemophilus influenzae: results from an university hospital in Istanbul

Journal of Global Antimicrobial Resistance
AIM: To determine in vitro susceptibilities of H. influenzae strains and to reveal the beta-lactam resistance mechanisms involved in those resistant to beta-lactams in our center. METHODS: Antibiotic susceptibilities of 122 H. influenzae isolated in 2022

Beta-lactamase induction and cell wall metabolism in Gram-negative bacteria

Frontiers in Microbiology, 2013
Production of beta-lactamases, the enzymes that degrade beta-lactam antibiotics, is the most widespread and threatening mechanism of antibiotic resistance.

Live to cheat another day: bacterial dormancy facilitates the social exploitation of beta-lactamases [PDF]

, 2015
The breakdown of antibiotics by β-lactamases may be cooperative, since resistant cells can detoxify their environment and facilitate the growth of susceptible neighbours. However, previous studies of this phenomenon have used artificial bacterial vectors

Management of Beta-Lactam Antibiotics Allergy: A Real-Life Study

Frontiers in Allergy, 2022
Beta-lactam allergy is a common problem in everyday medical practice and is recognized as a major public health issue. Carrying this label frequently leads to the avoidance of all beta-lactam antibiotics, favoring the use of other less preferred classes ...

Comparison of the Respiratory Resistomes and Microbiota in Children Receiving Short versus Standard Course Treatment for Community-Acquired Pneumonia

mBio, 2022
Pediatric community-acquired pneumonia (CAP) is often treated with 10 days of antibiotics. Shorter treatment strategies may be effective and lead to less resistance. The impact of duration of treatment on the respiratory microbiome is unknown.

A potential space-making role in cell wall biogenesis for SltB1and DacB revealed by a beta-lactamase induction phenotype in Pseudomonas aeruginosa

mBio
Pseudomonas aeruginosa encodes the beta-lactamase AmpC, which promotes resistance to beta-lactam antibiotics. Expression of ampC is induced by anhydro-muropeptides (AMPs) released from the peptidoglycan (PG) cell wall upon beta-lactam treatment. AmpC can
