RT Journal Article SR Electronic T1 Effects of minocycline and tetracycline on the vaginal yeast flora. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 403 OP 406 DO 10.1136/jcp.28.5.403 VO 28 IS 5 A1 J D Oriel A1 P M Waterworth YR 1975 UL http://jcp.bmj.com/content/28/5/403.abstract AB Two groups of women with non-specific genital infection were treated for two weeks with tetracycline 250 mg six-hourly and minocycline 100 mg twice daily respectively. Cultures for yeasts were performed before treatment and at the end of the first and second weeks. Before treatment yeasts, mostly Candida albicans, were recovered from 13% of the women. After one and two weeks' treatment yeasts were isolated from 22 and 29% of women treated with tetracycline, and from 19 and 29% of women treated with minocycline. It is concluded that despite inhibition of the growth of yeasts shown by minocycline in vitro, there is no evidence of any significant difference between the actions of tetracycline and minocycline on the vaginal yeast flora.
