The main components were camphor (17.74%), <jats:italic>\u03b1<\/jats:italic>\u2010pinene (9.66%), germacrene D (7.55%), 1,8\u2010cineole (7.24%), <jats:italic>trans<\/jats:italic>\u2010<jats:italic>\u03b2<\/jats:italic>\u2010caryophyllene (7.02%), and artemisia ketone (6.26%). The antimicrobial activity of this essential oil was evaluated by determining the following parameters: minimal inhibitory concentration (<jats:italic>MIC<\/jats:italic>), minimal bactericidal concentration (<jats:italic>MBC<\/jats:italic>), minimal fungicidal concentration (<jats:italic>MFC<\/jats:italic>), and minimal biofilm eradication concentration (<jats:italic>MBEC<\/jats:italic>). Moreover, the soluble virulence factors were quantified with different biochemical substrates incorporated in the culture media. The reference and resistant, clinical strains proved to be susceptible to the <jats:italic>A. annua<\/jats:italic> oil, with <jats:italic>MIC<\/jats:italic>s ranging from 0.51 to 16.33\u2005mg\/ml. The tested essential oil also showed good antibiofilm activity, inhibiting both the initial stage of the microbial cell adhesion to the inert substratum and the preformed mature biofilm. When used at subinhibitory concentrations, the essential oil proved to inhibit the phenotypic expression of five soluble virulence factors (hemolysins, gelatinase, DNase, lipases, and lecithinases). Briefly, the present results showed that the <jats:italic>A. annua<\/jats:italic> essential oil contained antimicrobial compounds with selective activity on <jats:italic>Gram<\/jats:italic>\u2010positive and <jats:italic>Gram<\/jats:italic>\u2010negative bacterial strains as well as on yeast strains and which also interfere with the expression of cell\u2010associated and soluble virulence factors.<\/jats:p>","DOI":"10.1002\/cbdv.201400340","type":"journal-article","created":{"date-parts":[[2015,10,13]],"date-time":"2015-10-13T22:03:19Z","timestamp":1444773799000},"page":"1554-1564","source":"Crossref","is-referenced-by-count":54,"title":["Chemical Composition and Antipathogenic Activity of <i>Artemisia annua<\/i> Essential Oil from Romania"],"prefix":"10.1002","volume":"12","author":[{"given":"Ioana C.","family":"Marinas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliza","family":"Oprea","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana Carmen","family":"Chifiriuc","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irinel Adriana","family":"Badea","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihaela","family":"Buleandra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica","family":"Lazar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,10,13]]},"reference":[{"key":"e_1_2_1_1_2","first-page":"41","volume":"85","author":"Follak S.","year":"2013","journal-title":"Preslia"},{"key":"e_1_2_1_2_2","first-page":"97","volume":"74","author":"Py\u0161ek P.","year":"2002","journal-title":"Preslia"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1523-1739.2004.00300.x"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pbio.0040140"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1641\/0006-3568(2000)050[0053:EAECON]2.3.CO;2"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.indcrop.2011.07.024"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2012.02.195"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules15053135"},{"key":"e_1_2_1_9_2","first-page":"44","volume":"18","author":"Huang L.","year":"1993","journal-title":"Zhongguo Zhong Yao Za Zhi"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.3892\/ijo_00000647"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0168-1656(01)00285-1"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2002-32570"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.phymed.2009.07.016"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jep.2012.03.024"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2006-959408"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.indcrop.2009.07.006"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules15117603"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1158\/1078-0432.CCR-08-0197"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1086\/503051"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jep.2013.08.021"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1080\/14786419.2012.662652"},{"key":"e_1_2_1_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fct.2013.04.016"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1099-1026(199707)12:4<241::AID-FFJ641>3.0.CO;2-Z"},{"key":"e_1_2_1_24_2","doi-asserted-by":"publisher","DOI":"10.1080\/10412905.1991.9697903"},{"key":"e_1_2_1_25_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00029850"},{"key":"e_1_2_1_26_2","doi-asserted-by":"publisher","DOI":"10.3390\/molecules17032542"},{"key":"e_1_2_1_27_2","doi-asserted-by":"publisher","DOI":"10.1021\/jf048429n"},{"key":"e_1_2_1_28_2","first-page":"121","volume":"43","author":"Leite A.
