Protocol for survival assay of Caenorhabditis elegans to Pseudomonas aeruginosa PA14 infection.

Junqiang Liu | Ming Lei | Mengqi Wang | Shu Chen | Haijun Tu
STAR protocols | 2024

The nematode Caenorhabditis elegans is a powerful model organism for studying the molecular and cellular mechanisms of innate immunity governed by the intestine. Here, we present a protocol to perform C. elegans survival assays to infection by the bacterial pathogen Pseudomonas aeruginosa PA14. Specifically, we describe steps for preparing C. elegans strains and PA14 bacteria for survival assays. This protocol will assist researchers to study genes involved in intestinal innate immunity and gut defense against pathogen infection. For complete details on the use and execution of this protocol, please refer to Liu et al.1 and Zheng et al.2.

WormBook The Online Review of C. Elegans Biology (tool)

RRID:SCR_006692

WormBook is a comprehensive, open-access collection of original, peer-reviewed chapters covering topics related to the biology of Caenorhabditis elegans and other nematodes. Wormbook also contains WormMethods, a collection of protocols for nematode researchers, and the Worm Breeder''s Gazette, an informal, non-refereed, biannual newsletter for the interchange of ideas and information related to C. elegans and other nematodes. WormBook is the online text companion to WormBase, the C. elegans model organism database. WormBook contains original reviews on all aspects of C. elegans biology and up-to-date descriptions of technical procedures used to study this animal. WormBook Sections: *Genetics and genomics *Molecular biology *Biochemistry *Cell biology *Developmental control *Post-embryonic development *Sex determination *The germ line *Signal transduction *Neurobiology and behavior *Evolution and ecology *Disease models and drug discovery
