To achieve this, P. aeruginosa was cultured in various water microcosms for 12 months under fixed (pH, nutrients and temperature) factors. P. aeruginosa responses to these conditions were investigated using colony morphotype, biochemical and enzymatic characterisation, pyocin typing, serotyping, sensitivity to different classes of antibiotics and molecular identification. Results show that starvation in water microcosms lead to unusual phenotypes. Of interest is that the pyocin changed from 24\/n in the wild type to 83\/a following culture in the water microcosms, and the serotype changed from O6 in the wild type to O1 in microcosm-cultured P. aeruginosa. Furthermore, the starvation period in various aquatic microcosms enhanced the resistance of P. aeruginosa against beta-lactam antibiotics. Compared to the other aquatic environments, the seawater microcosm produced the greatest amount of variations in P. aeruginosa. Overall, data demonstrated a high adaptability of P. aeruginosa to environmental changes. This may explain the unusual antibiotic-resistant phenotypes belonging to P. aeruginosa species, and their capacity for spreading that leads to human infections.<\/jats:p>","DOI":"10.2166\/wh.2011.072","type":"journal-article","created":{"date-parts":[[2012,2,23]],"date-time":"2012-02-23T16:58:31Z","timestamp":1330016311000},"page":"130-139","update-policy":"http:\/\/dx.doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":4,"title":["Phenotypic stress response of Pseudomonas aeruginosa following culture in water microcosms"],"prefix":"10.2166","volume":"10","author":[{"given":"Jihane","family":"Cheriaa","sequence":"first","affiliation":[{"name":"Laboratory of Analysis, Treatment, Valorisation and Environmental Pollution and Products \u2018LR01ES16\u2019, Faculty of Pharmacy, Monastir Avicenne Street, 5000 Monastir, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahmoud","family":"Rouabhia","sequence":"first","affiliation":[{"name":"Groupe de recherche en \u00e9cologie buccale, Facult\u00e9 de M\u00e9decine dentaire, 2420 rue de la Terrasse, Universit\u00e9 Laval, Qu\u00e9bec G1V 0A6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makaoui","family":"Maatallah","sequence":"first","affiliation":[{"name":"Laboratory of Analysis, Treatment, Valorisation and Environmental Pollution and Products \u2018LR01ES16\u2019, Faculty of Pharmacy, Monastir Avicenne Street, 5000 Monastir, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amina","family":"Bakhrouf","sequence":"first","affiliation":[{"name":"Laboratory of Analysis, Treatment, Valorisation and Environmental Pollution and Products \u2018LR01ES16\u2019, Faculty of Pharmacy, Monastir Avicenne Street, 5000 Monastir, Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"945","published-online":{"date-parts":[[2012,12,20]]},"container-title":["Journal of Water and Health"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/iwaponline.com\/jwh\/article-pdf\/10\/1\/130\/395185\/130.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/iwaponline.com\/jwh\/article-pdf\/10\/1\/130\/395185\/130.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,26]],"date-time":"2020-03-26T23:58:54Z","timestamp":1585267134000},"score":1,"resource":{"primary":{"URL":"https:\/\/iwaponline.com\/jwh\/article\/10\/1\/130\/1927\/Phenotypic-stress-response-of-Pseudomonas"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,3,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2012,12,20]]},"published-print":{"date-parts":[[2012,3,1]]}},"URL":"https:\/\/doi.org\/10.2166\/wh.2011.072","relation":{},"ISSN":["1477-8920","1996-7829"],"issn-type":[{"value":"1477-8920","type":"print"},{"value":"1996-7829","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2012,3,1]]},"published":{"date-parts":[[2012,3,1]]}}}
