College of Education for Pure Sciences, Samarra University discussed a Ph.D. thesis on phenotypic and molecular diagnosis of fungi isolated from some disease cases in the city of Samarra and studied the inhibitory effect of algal extracts on them. by the postgraduate student, Ms. Rasha Abdul-Adhim Yassin.

The thesis highlighted opportunistic fungi (yeasts and molds) that cause fungal infections isolated from various diseases and to study the effect of antifungals on the most common species, molecularly identifying the most common fungi resistant to antifungals based on the ITS4 ITS1 segment of the RNA 5.8 gene and conducting nucleotide sequence analysis.

The thesis demonstrated the prevalence of yeasts and fungi among immunocompromised individuals, the most frequently isolated fungi in children and cancer patients were Candida tropicalis, accounting for 58% and 55%, respectively, other Candida species and dermatophytes were also present. Clotrimazole, the antifungal with the greatest effect on fungi and yeasts, was also the antifungal.
