Objective: Mating in Ascomycete fungi is governed by mating type gene region called the MAT locus. The MAT locus contains idiomorphic sequences that are dissimilar in two opposite mating types.In fungi belonging to the Pezizomycotina subphylum, each MAT idiomorph encodes an alpha domain and an HMG (High Mobility Group) domain transcription factor. Although the alpha domain and the HMG domain transcription factor genes are indispensable components, the structure of the MAT locus (length), the gene content, and the transcriptional directions of the genes differ among fungi. This study aimed to evaluate the characterization of mating type of Candida albicans isolated from blood samples in our labouratory culture collection.

Method: Using the multiplex PCR technique, 486 bp and 515 bp of the DNA region of MTLa and MTLα primers in the C. albicans genome were determined, respectively.

Results: 156 C. albicans isolates showed 155 MTLa/α (99.4%) and 1 MTLα/α (0.6%).

Conclusion: Determination of MTL is essential both for making molecular genetic studies more efficient and for understanding the nature of this pathogenic fungus.
