The relationship between oral Candida carriage and the secretor status of blood group antigens in saliva.

Objective: The aim of the study was to investigate the relationship between oral Candida carriage and the secretor status of blood group antigens.

Study Design: Unstimulated whole saliva and oral rinse samples were obtained from 180 healthy subjects. These samples were plated on Sabouraud's dextrose agar media to determine oral Candida carriage. Sodium dodecylsulfate polyacrylamide gel electrophoresis and immunoblotting were performed on whole saliva samples to determine the secretor status of blood group antigens.

Results: The oral Candida carriage rate was found to be 45.0%. The sensitivity of the concentrated rinse culture proved to be superior. Oral Candida carriage was not significantly related to the blood group or secretor status of ABH or Lewis antigens. No significant relationship was found between oral Candida carriage and salivary flow rate. However, smoking affected oral Candida carriage.

Conclusion: Oral Candida carriage in healthy individuals is not significantly related to blood group or secretor status.
