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

BMC Microbiology, 2010 Background Biofilms are ubiquitous. For instance, the majority of medical infections are thought to involve biofilms. However even after decades of investigation, the in vivo efficacy of many antimicrobial strategies is still debated suggesting there is ...

Social interactions in the Burkholderia cepacia complex : biofilms and quorum sensing [PDF]
, 2010 Burkholderia cepacia complex bacteria are opportunistic pathogens that cause respiratory tract infections in susceptible patients, mainly people with cystic fibrosis. There is convincing evidence that B.

Genome-Wide Transposon Screen of a Pseudomonas syringae mexB Mutant Reveals the Substrates of Efflux Transporters. [PDF]
, 2019 Bacteria express numerous efflux transporters that confer resistance to diverse toxicants present in their environment. Due to a high level of functional redundancy of these transporters, it is difficult to identify those that are of most importance in ...

Staphylococcus aureus Persisters Tolerant to Bactericidal Antibiotics [PDF]
Microbial Physiology, 2012 Bacterial persister cells are non- or slow-growing reversible phenotypic variants of the wild type, tolerant to bactericidal antibiotics. We analyzed here Staphylococcus aureus persister levels by monitoring colony-forming unit counts of planktonically grown cells treated with six different antimicrobials over time.

Compounding Effects of Climate Warming and Antibiotic Resistance. [PDF]
, 2020 Bacteria have evolved diverse mechanisms to survive environments with antibiotics. Temperature is both a key factor that affects the survival of bacteria in the presence of antibiotics and an environmental trait that is drastically increasing due to ...

In vivo selection of resistant E. coli after ingestion of milk with added drug residues. [PDF]
, 2014 Antimicrobial resistance represents a major global threat to modern medicine. In vitro studies have shown that very low concentrations of drugs, as frequently identified in the environment, and in foods and water for human and animal consumption, can ...

Does diagnostic uncertainty increase antibiotic prescribing in primary care?
npj Primary Care Respiratory Medicine, 2021 This study aimed to determine the association between factors relevant to diagnostic uncertainty and physicians’ antibiotic-prescribing behaviour in primary care.

Regulating Antibiotic Tolerance within Biofilm Microcolonies [PDF]
Journal of Bacteriology, 2012 Antibiotic resistance/tolerance in biofilms is a multifactorial process. In this issue of the Journal of Bacteriology, Liao and Sauer identify the first transcriptional regulator to be linked to biofilm-specific antibiotic resistance.
