The Department of Biology at the College of Education and Pure Sciences at the University of Karbala discussed a master’s thesis entitled (Evaluating the effectiveness of some fungal and nanofilters against black fungus outside the body) by the student (Nabaa Muhammad Obeis) and supervised by (Prof. Dr. Ban Taha Muhammad). And there was a group of recovered people with natural Covid-19 disease, where a group appeared to be highly antagonistic against the black Covid fungus, Rhizopus spp, to zinc and silver nanoparticles. And I discovered that the percentage of mushroom appearance is good in the picture. The study recommended that fungal filtrates with silver and zinc nanoparticles can be used to inhibit black fungus in the medical field to reduce the spread of fungal mycelium in infection areas by taking environmentally friendly nanomaterials. These effluents are characteristic of the surroundings of laboratory animals. The student obtained an honors degree.
