Characterization of Candida albicans colony-morphology mutants and their hybrids
The relationship between inflammatory bowel disease and microorganisms was evaluated. The presence of Candida albicans-specific IgM and IgG antibodies in serum samples and the presence of C. albicans in stool and colonal mucosa samples of the patients did not exhibit any significant difference between 21 patients in active stage and 15 patients in remission of ulcerative colitis (UC) (compared with 19 control patients). The invasion of yeast cells to the colonal mucosa was demonstrated by detecting C. albicans DNA using specific PCon1, PCon2, and PspA2 primers in PCR assay. Eighteen of 36 patients (50%) were found to be DNA positive while in 19 controls only 4 (21%) were found to be positive. The presence of DNA in the association of the positive serological reactivity is suggested as an important diagnostic marker of UC.

Secreted aspartyl proteinase (Sap) distribution among different C. albicans isolates was determined using SAP-specific primers in polymerase chain reaction (PCR) assay. SAP1, SAP2, and SAP3 were detected in 13 of 40 (32.5%), SAP4 in 38/40 (95%), SAP5 were detected in 30/40 (75%), SAP6 in 23/40 (57.5%) of C. albicans strains isolated from blood cultures. SAP1-SAP3 were detected in 37 of 40 (92.5%), SAP4 were detected in 3/40 (7.5%), SAP5 in 3/40 (7.5%), SAP6 in 5/40 (12.5%) of C. albicans strains isolated from vaginal swab cultures. Sap1, Sap2 and Sap3 isoenzymes were found to be related to the vaginopathic potential of C. albicans; Sap4, Sap5 and Sap6 isoenzymes were found to be correlated with systemic infections.

A wild-type strain of Candida albicans (S1, ATCC 10261) was used to obtain stable auxotrophic colony morphological mutants (mutant M5 producing only true hyphae and mutant M2 containing 90 % blastospores and 10 % pseudohyphae) by induced mutagenesis. A hybrid was produced by somatic hybridization between these 2 mutants. Out of the isolated 10 clones, 2 stable hybrid clones were chosen and characterized: clone VI. 1M produced rough colonies containing a new, extended cell type (never observed in natural isolates), exhibited unipolar budding, did not form a germ tube, and possessed 12 chromosomal bands. All other features (antifungal and stress sensitivity, adhesion ability, pathogenicity, and isoenzyme and RAPD patterns) were similar to those of mycelial mutant M5. In contrast, the characteristics of clone VI.9S were similar to those of morphological mutant M2.
