Staphylococcal Biofilms [PDF]

open access: yesMicrobiology Spectrum, 2008
ABSTRACTStaphylococci, with the leading speciesStaphylococcus aureusandStaphylococcus epidermidis, are the most frequent causes of infections on indwelling medical devices. The biofilm phenotype that those bacteria adopt during device-associated infection facilitates increased resistance to antibiotics and host immune defenses. This review presents and

Aerial Exposure to the Bacterial Volatile Compound Trimethylamine Modifies Antibiotic Resistance of Physically Separated Bacteria by Raising Culture Medium pH

open access: yesmBio, 2014
Bacteria release a wide diversity of small bioactive molecules that often correspond to secondary metabolites. Among them, volatile molecules produced under various growth conditions were shown to mediate cross-kingdom interactions with plants, nematodes,

Virulence Factors in Coagulase-Negative Staphylococci

open access: yesPathogens, 2021
Coagulase-negative staphylococci (CoNS) have emerged as major pathogens in healthcare-associated facilities, being S. epidermidis, S. haemolyticus and, more recently, S. lugdunensis, the most clinically relevant species.

Disordered mesoporous silica particles: an emerging platform to deliver proteins to the lungs

open access: yesDrug Delivery
Pulmonary delivery and formulation of biologics are among the more complex and growing scientific topics in drug delivery. We herein developed a dry powder formulation using disordered mesoporous silica particles (MSP) as the sole excipient and lysozyme,

De novo evolved interference competition promotes the spread of biofilm defectors

open access: yesNature Communications, 2017
The production of secreted polymers in bacterial biofilms is costly, and therefore mechanisms preventing invasion of non-producing mutants are hypothesized.

Privatization of Biofilm Matrix in Structurally Heterogeneous Biofilms

open access: yesmSystems, 2019
Biofilms are communities of bacteria protected by a self-produced extracellular matrix. The detrimental effects of nonproducing individuals on biofilm development raise questions about the dynamics between community members, especially when isogenic nonproducers exist within wild-type populations.

Crystal Violet Staining Alone Is Not Adequate to Assess Synergism or Antagonism in Multi-Species Biofilms of Bacteria Associated With Bacterial Vaginosis

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Bacterial Vaginosis (BV) involves the presence of a multi-species biofilm adhered to vaginal epithelial cells, but its in-depth study has been limited due to the complexity of the bacterial community, which makes the design of in vitro models challenging.

The sociobiology of biofilms [PDF]

open access: yesFEMS Microbiology Reviews, 2009
Biofilms are densely packed communities of microbial cells that grow on surfaces and surround themselves with secreted polymers. Many bacterial species form biofilms, and their study has revealed them to be complex and diverse. The structural and physiological complexity of biofilms has led to the idea that they are coordinated and cooperative groups ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
