Water samples were obtained from two wells in Garoua (north Cameroun). Autoclaving at 121\u00b0C for 15\u2009min and filtration through 0.2\u2009\u00b5m filter were used to make microcosms. Microcosms were constituted of unfiltered-autoclaved, filtered-nonautoclaved, and filtered-autoclaved well waters. Bacterial strains were inoculated at initial cell concentration of 3\u2009Log<jats:sub>10<\/jats:sub>CFU\/mL. All strains were able to survive\/grow in used microcosms, and a maximal concentration of 5.61\u2009Log<jats:sub>10<\/jats:sub>CFU\/mL was observed. Survival abilities were strain and microcosm dependent. The declines were more pronounced in filtered-nonautoclaved water than in the other microcosms. <jats:italic>E. coli<\/jats:italic> and <jats:italic>Salmonella<\/jats:italic> sp.

Competition for nutrients and\/or thermolabile antimicrobial substances synthesized by \u201cultramicrocells\u201d or by the autochthonous bacteria retained by the filter might affect the bacterial survival.<\/jats:p>","DOI":"10.1155\/2013\/127179","type":"journal-article","created":{"date-parts":[[2013,8,7]],"date-time":"2013-08-07T21:03:52Z","timestamp":1375909432000},"page":"1-7","source":"Crossref","is-referenced-by-count":17,"title":["Survival and Growth of <i>Vibrio cholerae<\/i>, <i>Escherichia coli<\/i>, and <i>Salmonella<\/i> Spp. in Well Water Used for Drinking Purposes in Garoua (North Cameroon)"],"prefix":"10.1155","volume":"2013","author":[{"given":"Moussa","family":"Djaouda","sequence":"first","affiliation":[{"name":"University of Maroua, Higher Teachers\u2019 Training College, P.O.
