AbstractA total of eight bacterial isolates belonging to six species, and a select group of 12 oral Candida albicans isolates, were used to study the effect of bacteria on germ-tube formation. Briefly, each bacterial suspension (105-6 cells/ml) was mixed with a C. albicans suspension (107 cells/ml) and incubated at 37°C for 90 min with bovine serum, and the percentage germ-tube-positive Candida cells was quantified using a haemocytometer, under light microscopy. In general, out of eight bacteria, Streptococcus sanguis SK21 A, Streptococcus salivarius SK56, Escherichia coli ATCC 25922, and S. salivarius OBU3 suppressed germ-tube formation to varying degrees, with different C. albicans isolates. Porphyromonas gingivalis Pg 50, Lactobacillus casei ATCC 7469 and Prevotella intermedia OBU4 elicited significant enhancement of germ-tube formation, whereas S. sanguis OBU 2 had no effect. E. coli ATCC 25922 was the only organism to show statistically significant suppression of germ-tube formation (p=0.0312). A significant increase in the germ tube production of C. albicans isolated from HIV-infected compared with HIV-free individuals was also noted. The current results tend to suggest that commensal and transient oral bacterial populations may selectively influence the differential expression of germ-tube-forming ability of C. albicans isolates.
