In this study, the capacity of 30 strains of lactobacilli to coaggregate withCandida albicans ATCC 10239,C. albicans AJD 180 andCandida krusei ATCC 6258 were studiedin vitro. A marked coaggregation withC. albicans was observed for two strains ofLactobacillus crispatus, a strain ofLactobacillus cellobiosus and a strain ofLactobacillus salivarius. Coaggregation occurred at a pH range from 3 to 7, some strains showing optimal binding at high and other strains at low pH. Treatment of lactobacilli at 70 or 85°C for 20 min or treatment of the bacteria with pepsin abolished their capacity of coaggregation. The results may be of importance when trying to establish probiotics for vaginal use.
