Oral Candida carriage and blood group antigen secretor status were exa
mined in 92 healthy, young volunteers. Candida was isolated from 61 of
92 saliva samples (66% Candida carriage). In 76% of cases this was Ca
ndida albicans. Oral Candida carriage was found to be significantly as
sociated with non-secretion of blood group antigens (P<0.05). However,
the numbers of Candida were higher in the saliva of secretors than of
nonsecretors (P<0.01). A higher percentage of Candida carriage was ob
served in individuals with blood group O. Thus, the finding of higher
carrier frequency in the non-secretors and in blood group O subjects i
s confirmed.
