However, the major structural features of indole analogues that govern antivirulence activity remain unexplored. Therefore, we investigated the impact of 26 indole analogues on indole-regulated virulence phenotypes in <i>Vibrio campbellii</i> and on the virulence of the bacterium in a gnotobiotic brine shrimp model. The results demonstrated that 10 indole analogues significantly increased the fluorescence of indole reporter strain <i>Vibrio cholerae</i> S9149, 21 of them decreased the swimming motility of <i>V. campbellii</i>, and 13 of them significantly decreased the biofilm formation of <i>V. campbellii</i>. Further, we found that 1-methylindole, indene, 2,3-benzofuran, thianaphthene, indole-3-acetonitrile, methyl indole-3-carboxylate, 3-methylindole, and indole-2-carboxaldehyde exhibited a significant protective effect on brine shrimp larvae against <i>V. campbellii</i> infection, resulting in survival rates of challenged brine shrimp above 80%. The highest survival of shrimp larvae (98%) was obtained with indole-3-acetonitrile, even at a relatively low concentration of 20 μM. Importantly, the indole analogues did not affect bacterial growth, both in vitro and in vivo. These results indicate the potential of indole analogues in applications aiming at the protection of shrimp from vibriosis.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Indole analogues decreasing the virulence of <i>Vibrio campbellii</i> towards brine shrimp larvae","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-02-28","DateCreate":"2023-02-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000879095400001","VABBcode":null,"OpenAcc":1,"DOI":"10.1111/1751-7915.14160"},"refs":null,"anarec":{"AnaID":361499,"PubliDate":2022,"Pagination":"2917-2928","XtraPublOfAnaID":null,"ISBN":null,"Volume":"15","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":187396,"SerRR":"Microbial Biotechnology.
