As an example, ingestion of <i>Escherichia coli</i> overproducing prokaryotic Hsps significantly improves survival of gnotobiotically cultured <i>Artemia</i> larvae upon challenge with pathogenic <i>Vibrio campbellii</i>. The relationship between Hsp accumulation and enhanced resistance to infection may involve DnaK, the prokaryotic equivalent to Hsp70, a major molecular chaperone in eukaryotic cells. In support of this proposal, heat-stressed bacterial strains LVS 2 (<i>Bacillus</i> sp.), LVS 3 (<i>Aeromonas hydrophila</i>), LVS 8 (<i>Vibrio</i> sp.), GR 8 (<i>Cytophaga</i> sp.), and GR 10 (<i>Roseobacter</i> sp.) were shown in this work to be more effective than nonheated bacteria in protecting gnotobiotic <i>Artemia</i> larvae against <i>V. campbellii</i> challenge. Immunoprobing of Western blots and quantification by enzyme-linked immunosorbent assay revealed that the amount of DnaK in bacteria and their ability to enhance larval resistance to infection by <i>V. campbellii</i> are correlated. Although the function of DnaK is uncertain, it may improve tolerance to <i>V. campbellii</i> via immune stimulation, a possibility of significance from a fundamental perspective and also because it could be applied in aquaculture, a major method of food production.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Ingestion of bacteria overproducing DnaK attenuates <i>Vibrio</i> infection of <i>Artemia franciscana</i> larvae","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-25 01:32:16.453320","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Bacteria; Heat shock proteins; DnaK; Vibriosis; Artemia","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2020-06-19","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000271527800006","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s12192-009-0112-2"},"refs":null,"anarec":{"AnaID":257864,"PubliDate":2009,"Pagination":"603-609","XtraPublOfAnaID":null,"ISBN":null,"Volume":"14","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":122291,"SerRR":"Cell Stress and Chaperones.
