After the samples are obtained, the research's goal is to determine A. fumigatus, the fungus that causes disease and a severe type of pneu-monia that can be fatal. This method entails processing DNA with precise and balanced amounts of primers. As a result, after the migra-tion process ended, suitable images were obtained, which served as a helpful reference for differentiating the isolates. If the band was cut from the gel after staining, more single bands with particular molecular weights emerged to benefit from those bands by their dimensions for research and other studies. Furthermore, some of the pioneers of this approach can discern between medical and environmental iso-lates. ISSR4 effectiveness has been shown in ISSR4 and proved that it's efficient in identifying between the first medical isolate, which has two bands with a molecular weight of 500bp, and yet another of 350bp.In contrast, he observed single bands in the seven environmental isolates that were connected to a weight of 250. In contrast to his companion, ISSR3, who was unable to distinguish that group of isolates with distinctive single bands, it was determined that he was a special baddie in that he was able to distinguish both isolates with distinct weights and a polymorphism card equal to 100 with high efficiency. In opposition to ISSR 9, the joke in that group's initiator, which is superior to the remainder of the group, ISSR 5 is exceptionally fragile. Concerning a total of five independent packages for medical isola-tion, each of which has an efficiency of one and a polymorphism of 100 within the molecular weight range of 900, 600, 350, and 250 bp. He was able to accurately differentiate across the two isolates utilizing a molecular weight difference of 200bp. for one packet of the isolate derived from river water.
