Despite recent advances, their virulence factors remain incompletely studied, and siderophore production has not yet been investigated in this genus. The aim of this study was to evaluate the production of siderophores in a large collection of\n              <jats:italic>Achromobacter<\/jats:italic>\n              spp. and evaluate the variability according to the origin of the strain and species. A total of 163 strains were studied, including 128 clinical strains (CF and non-CF patients) and 35 strains of environmental origin. Siderophores were quantified by the liquid chrome azurol-sulphonate assay. Species were identified by\n              <jats:italic>nrdA<\/jats:italic>\n              gene-based phylogeny. Strains were assigned to 20 species, with\n              <jats:italic>Achromobacter xylosoxidans<\/jats:italic>\n              being the most represented (51.5% of strains). Siderophore production was observed in 72.4% of the strains, with amounts ranging from 10.1% to 90% siderophore units. A significantly higher prevalence of siderophore-producing strains and greater production of siderophores were observed for clinical strains compared with strains of environmental origin. Highly variable observations were made according to species:\n              <jats:italic>A. xylosoxidans<\/jats:italic>\n              presented unique characteristics (one of the highest prevalence of producing strains and highest amounts produced, particularly by CF strains). Siderophores are important factors for bacterial growth commonly produced by members of the\n              <jats:italic>Achromobacter<\/jats:italic>\n              genus. The significance of the observations made during this study must be further investigated. Indeed, the differences observed according to species and the origin of strains suggest that siderophores may represent important determinants of the pathophysiology of\n              <jats:italic>Achromobacter<\/jats:italic>\n              spp. infections and also contribute to the particular epidemiological success of\n              <jats:italic>A. xylosoxidans<\/jats:italic>\n              in human infections.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>\n              <jats:italic>Achromobacter<\/jats:italic>\n              spp. are recognized as emerging opportunistic pathogens in humans with various underlying diseases, including cystic fibrosis (CF). Although their pathophysiological traits are increasingly studied, their virulence factors remain incompletely described. Particularly, siderophores that represent important factors of bacterial growth have not yet been studied in this genus. A population-based study was performed to explore the ability of members of the\n              <jats:italic>Achromobacter<\/jats:italic>\n              genus to produce siderophores, both overall and in relevant subgroups (\n              <jats:italic>Achromobacter<\/jats:italic>\n              species; strain origin, either clinical\u2014from CF or non-CF patients\u2014or environmental). This study provides original data showing that siderophore production is a common trait of\n              <jats:italic>Achromobacter<\/jats:italic>\n              strains, particularly observed among clinical strains. The major species,\n              <jats:italic>Achromobacter xylosoxidans<\/jats:italic>\n              , encompassed both one of the highest prevalence of siderophore-producing strains and strains producing the largest amounts of siderophores, particularly observed for CF strains. These observations may represent additional advantages accounting for the epidemiological success of this species.\n            <\/jats:p>\n          <\/jats:sec>","DOI":"10.1128\/spectrum.02953-23","type":"journal-article","created":{"date-parts":[[2024,2,5]],"date-time":"2024-02-05T14:00:51Z","timestamp":1707141651000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":16,"title":["Prevalence and variability of siderophore production in the\n            <i>Achromobacter<\/i>\n            genus"],"prefix":"10.1128","volume":"12","author":[{"given":"P.","family":"Sorlin","sequence":"first","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Brivet","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Jean-Pierre","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"},{"name":"Service de Microbiologie et d\u2019Hygi\u00e8ne hospitali\u00e8re, CHU de N\u00eemes, N\u00eemes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Aujoulat","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Besse","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Dupont","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"},{"name":"Laboratoire de Bact\u00e9riologie, CHU de Montpellier, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Chiron","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"},{"name":"Centre de Ressources et de Comp\u00e9tences de la Mucoviscidose, CHU de Montpellier, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Jumas-Bilak","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"},{"name":"Laboratoire d\u2019\u00c9cologie Microbienne Hospitali\u00e8re, CHU de Montpellier, Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Q.","family":"Menetrey","sequence":"additional","affiliation":[{"name":"INFINITE\u2014Institute for Translational Research in Inflammation, Universit\u00e9 de Lille, INSERM U1286, CHU Lille, Lille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2130-6335","authenticated-orcid":true,"given":"H.","family":"Marchandin","sequence":"additional","affiliation":[{"name":"HydroSciences Montpellier, Universit\u00e9 de Montpellier, CNRS, IRD, Montpellier, France"},{"name":"Service de Microbiologie et d\u2019Hygi\u00e8ne hospitali\u00e8re, CHU de N\u00eemes, N\u00eemes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.02293-13"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.01279-15"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/AEM.01739-18"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/jam.15796"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/microorganisms11040864"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200505-840OE"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(16)00576-6"},{"key":"e_1_3_5_9_2","volume-title":"Registre fran\u00e7ais de la mucoviscidose\u2013bilan des donn\u00e9es 2021","year":"2022","unstructured":"2022.
