Optimizing a reliable ex vivo human blood model to analyze expression of Staphylococcus epidermidis genes [PDF]

open access: yesPeerJ, 2020
Human blood is often used as an ex vivo model to mimic the environment encountered by pathogens inside the host. A significant variety of experimental conditions has been reported. However, optimization strategies are often not described.

Sessile Legionella pneumophila is able to grow on surfaces and generate structured monospecies biofilms [PDF]

open access: yes, 2010
Currently, models for studying Legionella pneumophila biofilm formation rely on multi-species biofilms with low reproducibility or on growth in rich medium, where planktonic growth is unavoidable.

Bacterial biofilms: a common cause of persistent infections.

open access: yesScience, 1999
Bacteria that attach to surfaces aggregate in a hydrated polymeric matrix of their own synthesis to form biofilms. Formation of these sessile communities and their inherent resistance to antimicrobial agents are at the root of many persistent and chronic

To Biofilm or Not to Biofilm?

open access: yesSoutheastern European Medical Journal, 2018
Aim: The goal of this research is to examine the biofilm forming ability of Staphylococcus aureus and Pseudomonas aeruginosa clinical isolates in different in vitro conditions using Meuller-Hinton and Luria-Bertani broths. Material and methods: 30 strains of Pseudomonas aeruginosa and 30 strains of Staphylococcus aureus obtained from clinical specimens

Increased Osmolarity in Biofilm Triggers RcsB-Dependent Lipid A Palmitoylation in Escherichia coli

open access: yesmBio, 2018
Biofilms are often described as protective shelters that preserve bacteria from hostile surroundings. However, biofilm bacteria are also exposed to various stresses and need to adjust to the heterogeneous physicochemical conditions prevailing within ...

Lifestyle-specific S-nitrosylation of protein cysteine thiols regulates Escherichia coli biofilm formation and resistance to oxidative stress

open access: yesnpj Biofilms and Microbiomes, 2021
Communities of bacteria called biofilms are characterized by reduced diffusion, steep oxygen, and redox gradients and specific properties compared to individualized planktonic bacteria.

Biofilms: Microbial Life on Surfaces

open access: yesEmerging Infectious Diseases, 2002
Microorganisms attach to surfaces and develop biofilms. Biofilm-associated cells can be differentiated from their suspended counterparts by generation of an extracellular polymeric substance (EPS) matrix, reduced growth rates, and the up- and down ...

Growth limiting conditions and denitrification govern extent and frequency of volume detachment of biofilms [PDF]

open access: yes, 2013
This study aims at evaluating the mechanisms of biofilm detachment with regard of the physical properties of the biofilm. Biofilms were developed in Couette–Taylor reactor under controlled hydrodynamic conditions and under different environmental growth ...
