- Hydrophobic interaction is generally considered to play an important role in the adherence of microorganisms to eukaryotic cells and also to certain inert surfaces. Using a microbe adhesion assay to hydrocarbons (n-hexadecane), 68 strains of Candida albicans and 30 non-albicans strains were studied. Influence of source of isolate, age of the culture, and percentage of germ tube formation on adhesion were studied. C. albicans blastoconidia were found to be hydrophilic; conversely, blastoconidia of non-albicans strains were slightly more hydrophobic. Germ tube formation was associated with a significant rise in cell surface hydrophobicity.

- OBJECTIVE AND STUDY DESIGN: We report for the first time an inhibitory effect on cell division and germ tube formation by Candida albicans and strains of other Candida species by putrescine and cadaverine. RESULTS: Both bacterial amines showed a dose-dependent inhibition of germ tube formation by C albicans, as well as budding (inhibition of cell division) of strains of other Candida species (ie, C glabrata, C krusei, and C tropicalis). CONCLUSIONS: We hypothesize that the presence of these and possibly other bacterial amines produced by anaerobes in the vaginal flora and seen in bacterial vaginosis, as in the healthy gut, may explain why candidosis is rarely seen in these instances.

- Pseudohyphae formation by Candida albicans blastoconidia, as seen in vaginal smears, is a phenotypical change commonly assumed to mean fungal invasiveness, i.e. not mere colonization. C. albicans forms germ tubes in vitro in the presence of serum. In our search for inhibitory components of germ tube formation, we decided to study fibrinogen. The inhibition of germ tube formation by clinical isolates of C. albicans was evaluated in the presence of serial concentrations of fraction I, type IV and fraction I, type Is of fibrinogen from bovine plasma. Fibrinogen showed a dose-dependent, pH-independent inhibitory effect on the germ tube formation by C. albicans.
