title: Vaginal colonization by Candida in asymptomatic women with and without a history of recurrent vulvovaginal candidiasis.
abstract: OBJECTIVE
  The asymptomatic carriage of Candida in the vagina of women with a history of recurrent vulvovaginal candidiasis was compared with that of women with no such history.
  
  
  METHODS
  Vaginal swabs from 50 women with a history of recurrent vulvovaginal candidiasis and 45 women with one or fewer episodes of candidal vaginitis within the past 12 months were evaluated for Candida by wet mount/Gram stain, culture, and polymerase chain reaction (PCR). All women were asymptomatic for at least 30 days.
  
  
  RESULTS
  Candida was identified in 28 women by PCR, in 14 women by culture, and in 13 women by wet mount/Gram stain. Candida was identified by PCR in a similar proportion of patients with previous recurrent vulvovaginal candidiasis (30%) and in controls (28.8%). However, Candida was identified by culture in more women with previous recurrent vulvovaginal candidiasis (22%) than in controls (6.6%, P = .04); it also was identified by wet mount/Gram stain in more women with recurrent vulvovaginal candidiasis (22%) than in controls (4.4%, P = .01). For the recurrent vulvovaginal candidiasis patients, culture and wet mount/Gram stain had a sensitivity of 66.6% compared with PCR. For the controls, the sensitivity of the two former assays relative to PCR was only 15.3%.
  
  
  CONCLUSIONS
  Women with a history of recurrent vulvovaginal candidiasis have more easily detectable Candida in their vagina, even when asymptomatic, than do other women. A relative inefficiency in regulating the proliferation of Candida in the vagina may increase susceptibility to periodic symptomatic recurrences.
