The aim of the present study was therefore to examine the differences, if any, in the biofilm-forming abilities of 26<jats:italic>Candida albicans<\/jats:italic>yeast isolates from HIV-infected individuals and 20 isolates from HIV-free individuals, as this attribute of yeast isolates from patients with HIV disease has not been examined before. Biofilm formation in microtiter plate wells was quantitatively determined by both the 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino) carbonyl]-2<jats:italic>H<\/jats:italic>-tetrazolium hydroxide (XTT) reduction method and the crystal violet method. Although candidal biofilm formation could be quantitatively evaluated by either technique, the better reproducibility (<jats:italic>P<\/jats:italic>&lt; 0.05) of the XTT reduction assay compared with that of the crystal violet method led us to conclude that the former is more reliable. There were no significant quantitative differences in biofilm formation between<jats:italic>C. albicans<\/jats:italic>isolates from HIV-infected patients and isolates from HIV-free individuals during in vitro incubation in a multiwell culture system over a period of 66 h. Three of eight host factors in the HIV-infected group were found to be associated with candidal biofilm formation. Thus, yeasts isolated from older individuals and those with higher CD4-cell counts exhibited decreased biofilm formation, while the findings for yeasts from individuals receiving zidovudine showed the reverse (<jats:italic>P<\/jats:italic>&lt; 0.05 for all comparison). Our data indicate that attributes other than biofilm formation may contribute to the increased oral yeast carriage rates in cases of HIV infection.<\/jats:p>","DOI":"10.1128\/jcm.41.7.2961-2967.2003","type":"journal-article","created":{"date-parts":[[2003,7,3]],"date-time":"2003-07-03T19:05:48Z","timestamp":1057259148000},"page":"2961-2967","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":218,"title":["Biofilm-Forming Ability of<i>Candida albicans<\/i>Is Unlikely To Contribute to High Levels of Oral Yeast Carriage in Cases of Human Immunodeficiency Virus Infection"],"prefix":"10.1128","volume":"41","author":[{"given":"Y.","family":"Jin","sequence":"first","affiliation":[{"name":"Divisions of Oral Bosciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.
