WebApr 11, 2024 · How can beneficial microorganisms be distinguished from pathogenic ones? In this issue of Immunity, Peterson et al. discovered that a specific phenazine, which is part of a family of toxic metabolites expressed by pathogenic bacteria, is detected by Caenorhabditis elegans by directly binding to a nuclear hormone receptor, promoting the …
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 … The different Caenorhabditis species occupy various nutrient- and bacteria-rich environments. They feed on the bacteria that develop in decaying organic matter (microbivory). Soil lacks enough organic matter to support self-sustaining populations. C. elegans can survive on a diet of a variety of bacteria, but its wild ecology is largely unknown. Most laboratory strains were taken from artificial environments such as gardens and compost piles. More recently, C. elegans has b…
