WebDec 1, 2024 · Abstract. Chemosensation is indispensable for the survival of Caenorhabditis elegans to discriminate food and pathogenic bacteria in their living environment. Food-like odors emitted by the pathogen Bacillus nematocida B16 for trapping its hosts and an … WebApr 11, 2024 · Being able to distinguish a microbe with a positive impact on the host from a pathogenic microbe is, however, crucial for survival. Caenorhabditis elegans lacks classic pattern-recognition receptors, but Peterson et al. discovered a cue that these nematodes use to identify harmful bacteria. Certain pathogenic bacteria express a specific ...

WebThis study explored the health and life-promoting properties of two LAB, Levilactobacillus brevis and Weizmannia coagulans, using the Caenorhabditis elegans model. We found that L. brevis and W. coagulans enhanced the intestinal integrity and intestinal barrier functions without affecting the overall physiological functions of C. elegans. WebDec 1, 2005 · The nematode Caenorhabditis elegans feeds on bacteria but is susceptible to infection by pathogenic bacteria in its natural environment. Here we show that C. elegans modifies its olfactory ... harvard undergraduate application
Pathogen metabolite checkpoint: NHR on guard - ScienceDirect
WebThe QS system is thought to ensure that pathogenic traits are expressed only when the bacterial population density is high enough to overwhelm the host before it is able to mount an efficient response.
