MetabolomicsMg2+ in drinking water exacerbates Salmonella Typhimurium T6SS-mediated intestinal bacterial competition through affecting metabolic reprogramming

By establishing a model of enteritis in mice infected with Salmonella Typhimurium, this study investigates the effects of ion concentration in drinking water on intestinal metabolites and microbiota structure in mice, as well as its influence on pathogen susceptibility and the host-patho...

MetabolomicsAntibiotics create a shift from mutualism to competition in human gut communities with a longer-lasting impact on fungi than bacteria

Background

Antibiotic treatment has a well-established detrimental effect on the gut bacterial composition, but effects on the fungal community are less clear. Bacteria in the lumen of the gastrointestinal tract may limit fungal colonization and invasion. Antibiotic drugs t...

TranscriptomicsDifferent isoforms of Maxwell´s Demon, a conserved cell membrane protein, mediate lose/win decisions during cell competition
Cell competition promotes the elimination of weaker cells from a growing population. Here we investigate how cells of Drosophila wing imaginal discs distinguish “winners” from “losers” during cell competition. Using genomic and functional assays we have identified Maxwell`s Demon (Mwd), a cell membr...

MetabolomicsResource Partitioning of Diatom Metabolites that Support Bacterial Heterotrophy in the Ocean (NMR assay)

The communities of marine bacteria that assemble around living microphytoplankton are predictably dominated by three taxonomic groups, each of which specializes in the use or transport of different components of the available metabolite pool: Rhodobacterales transport small and polar metabolites,...

ProteomicsProteomic analyses reveal the non-coding small RNA Qrr5 influences autoaggregation and growth competition in Vibrio parahaemolyticus
Vibrio parahaemolyticus, a sea-born bacterial pathogen, is a primary inducement of food-borne gastroenteritis. Most researches have shown that non-coding small RNA plays a vital role in the regulation of multiple biological processes in pathogenic bacteria, especially autoaggregation and growth comp...

TranscriptomicsListening in on a bacterial/fungal dialog: transcriptional profiling of an antagonistic interaction
The genus Collimonas consists of soil bacteria that are well known for their antifungal activity and for mycophagy, i.e. the ability to grow at the expense of living fungi. The aim of the current study was to gain a better understanding of the mechanisms of antagonism of Collimonas bacteria towards ...
