Bacterial communities of the oviduct of turkeys

open access: yesScientific Reports, 2022
AbstractBacterial communities in the reproductive tract of avian species play an important role in keeping birds healthy and encouraging growth. Infection can occur during egg formation with pathogens that can be transmitted to the embryo. In this study, we investigated the bacterial composition in the turkey reproductive tract using a taxa ...

Bacterial Quorum Sensing Allows Graded and Bimodal Cellular Responses to Variations in Population Density

open access: yesmBio, 2022
Quorum sensing (QS) is a mechanism of cell-cell communication that connects gene expression to environmental conditions (e.g., cell density) in many bacterial species, mediated by diffusible signal molecules.

From Insect Communication to Bacterial Communication [PDF]

open access: yesJournal of Chemical Ecology, 2014
One of the driving forces in the early stages of the ISCE and the Journal of Chemical Ecologywas the aim to unravel the chemistry and biology of insect communication. Since then, a remarkable number of insect pheromones have been identified, probably for about 1,000 species, and the mysteries of their formation and perception elucidated, in some cases ...

Amplifying the innate immune response : cell-cell propagation of proinflammatory signals during bacterial infection [PDF]

open access: yes, 2012
The enteroinvasive bacterium Shigella flexneri uses multiple secreted effector proteins to downregulate interleukin-8 (IL-8) expression in infected epithelial cells. Nevertheless, massive IL-8 secretion is observed in shigellosis. In this thesis, a novel

Community-acquired bacterial meningitis [PDF]

open access: yesNature Reviews Disease Primers, 2016
Meningitis is an inflammation of the meninges and subarachnoid space that can also involve the brain cortex and parenchyma. It can be acquired spontaneously in the community - community-acquired bacterial meningitis - or in the hospital as a complication of invasive procedures or head trauma (nosocomial bacterial meningitis).

Bacterial Communities: Interactions to Scale [PDF]

open access: yesFrontiers in Microbiology, 2016
In the environment, bacteria live in complex multispecies communities. These communities span in scale from small, multicellular aggregates to billions or trillions of cells within the gastrointestinal tract of animals. The dynamics of bacterial communities are determined by pairwise interactions that occur between different species in the community ...

Biological Activity of Volatiles from Marine and Terrestrial Bacteria

open access: yesMarine Drugs, 2010
The antiproliferative activity of 52 volatile compounds released from bacteria was investigated in agar diffusion assays against medically important microorganisms and mouse fibroblasts.

The defensome of complex bacterial communities

open access: yesNature Communications, 2023
AbstractBacteria have developed various defense mechanisms to avoid infection and killing in response to the fast evolution and turnover of viruses and other genetic parasites. Such pan-immune system (defensome) encompasses a growing number of defense lines that include well-studied innate and adaptive systems such as restriction-modification, CRISPR ...

A Mesorhizobium japonicum quorum sensing circuit that involves three linked genes and an unusual acyl-homoserine lactone signal

open access: yesmBio, 2023
Members of the genus Mesorhizobium, which are core components of the rhizosphere and specific symbionts of legume plants, possess genes for acyl-homoserine lactone (AHL) quorum sensing (QS).

Metabolomic Analysis of the Effect of Lippia origanoides Essential Oil on the Inhibition of Quorum Sensing in Chromobacterium violaceum

open access: yesAntibiotics, 2023
Bacteria can communicate through quorum sensing, allowing them to develop different survival or virulence traits that lead to increased bacterial resistance against conventional antibiotic therapy. Here, fifteen essential oils (EOs) were investigated for
