While the formation of\n            <jats:named-content content-type=\"genus-species\">V. cholerae<\/jats:named-content>\n            biofilms has been well studied, little is known about the dispersal from biofilms, particularly upon entry into the host. In this study, we found that the exposure of mature biofilms to physiologic levels of the bile salt taurocholate, a host signal for the virulence gene induction of\n            <jats:named-content content-type=\"genus-species\">V. cholerae<\/jats:named-content>\n            , induces an increase in the number of detached cells with a concomitant decrease in biofilm mass. Scanning electron microscopy micrographs of biofilms exposed to taurocholate revealed an altered, perhaps degraded, appearance of the biofilm matrix. The inhibition of protein synthesis did not alter rates of detachment, suggesting that\n            <jats:named-content content-type=\"genus-species\">V. cholerae<\/jats:named-content>\n            undergoes a passive dispersal. Cell-free media from taurocholate-exposed biofilms contains a larger amount of free polysaccharide, suggesting an abiotic degradation of biofilm matrix by taurocholate. Furthermore, we found that\n            <jats:named-content content-type=\"genus-species\">V. cholerae<\/jats:named-content>\n            is only able to induce virulence in response to taurocholate after exit from the biofilm. Thus, we propose a model in which\n            <jats:named-content content-type=\"genus-species\">V. cholerae<\/jats:named-content>\n            ingested as a biofilm has coopted the host-derived bile salt signal to detach from the biofilm and go on to activate virulence.\n          <\/jats:p>","DOI":"10.1128\/iai.02617-14","type":"journal-article","created":{"date-parts":[[2014,11,4]],"date-time":"2014-11-04T03:33:32Z","timestamp":1415072012000},"page":"317-323","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":70,"title":["Host Intestinal Signal-Promoted Biofilm Dispersal Induces Vibrio cholerae Colonization"],"prefix":"10.1128","volume":"83","author":[{"given":"Amanda J.","family":"Hay","sequence":"first","affiliation":[{"name":"Department of Microbiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)15328-7"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1369-5274(03)00032-8"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.01094-07"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.femsre.2004.09.003"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1218039110"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00203-006-0133-5"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.65.3.1131-1134.1997"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2958.2005.04846.x"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.70.1.121-126.2002"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2013.00375"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2958.1999.01624.x"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tim.2008.12.004"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1099\/mic.0.040196-0"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.ppat.1002210"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1128\/JB.186.5.1574-1578.2004"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1128\/JB.183.5.1716-1726.2001"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1534-5807(03)00295-8"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2958.2003.03688.x"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.1177\/0022034509359403"},{"key":"e_1_3_3_21_2","doi-asserted-by":"publisher","DOI":"10.1128\/JB.184.1.290-301.2002"},{"key":"e_1_3_3_22_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.ppat.1000052"},{"key":"e_1_3_3_23_2","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms5462"},{"key":"e_1_3_3_24_2","doi-asserted-by":"publisher","DOI":"10.1128\/JB.185.3.1027-1036.2003"},{"key":"e_1_3_3_25_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0237386100"},{"key":"e_1_3_3_26_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0706352104"},{"key":"e_1_3_3_27_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.00048-10"},{"key":"e_1_3_3_28_2","doi-asserted-by":"publisher","DOI":"10.1128\/IAI.74.2.1141-1147.2006"},{"key":"e_1_3_3_29_2","doi-asserted-by":"publisher","DOI":"10.1006\/plas.1996.0001"},{"key":"e_1_3_3_30_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M200109200"},{"key":"e_1_3_3_31_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1014640108"},{"key":"e_1_3_3_32_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ab.2004.12.001"},{"key":"e_1_3_3_33_2","volume-title":"Experiments in molecular genetics","author":"Miller J","year":"1972","unstructured":"Miller J. 1972.
