Diabetic mellitus is one of the main risk factors of fungal infections because poor glycemic control is associated with a high level of glucose in blood and saliva which could be treated as nutrient to fungi. This study aimed to isolate and identification of pathogenic fungi from diabetic patient. 140 samples were taken from different places of human body from the national center of diabetic patients that related to Mustansiriyah University / college of medicine and Al-yarmuk Hospital in Baghdad. 84 sample (60%) tested positive to fungi and 56 sample (40%) tested negative to fungi. The most frequented fungi isolated have been chosen for molecular identification by PCR (Millerozyma farinosa and Candida orthopsilosis) using specific primers (ITS1 and ITS 4) and phylogenetic structuring tree. Analysis was done by sequences and confirmation of microorganism’s homogenic data using database (NCBI) after amplification of Fungi’s ribosomal RNA. Result showed clinical isolate Milerozyma farinosa showed 100% compatibility and score (1112) and clinical isolate Candida orthpopsilosis showed 100% compatibility and score (893) with wild type of ITS gene from gene bank.
