title: Determination of salivary anticandidal activities in healthy adults and patients with AIDS: a pilot study.
abstract: This investigation compared the salivary anticandidal activities of 12 healthy adults with 12 hospitalized patients with AIDS. Stimulated parotid, submandibular-sublingual, and whole salivas were collected during a period of 10 min, immediately acidified, boiled, and then centrifuged to isolate salivary supernatants. Supernatants were then tested for antifungal activity against Candida albicans in blastospore viability inhibition and germ tube formation assays. A unit of blastospore or germ tube antifungal activity was established as that activity yielding 90% or greater inhibition during a defined time period in each salivary assay. Each of the patients with AIDS were found to be defective in one or more of their salivary antifungal activities, and in comparison with healthy adults the differences in antifungal units per milliliter of saliva and total antifungal units were statistically significant for each saliva and each antifungal assay. Defective salivary antifungal activity may contribute to the oral candidiasis seen in patients with AIDS.
