Isolate of Candida albicans was obtained from Kirkuk General Hospital. It was used to study its ability to prepare silver nanoparticles, and it was found that the silver nitrate solution in 1 mm changed its color to brown, which is a preliminary evidence for the formation of silver nanoparticles. The absorption spectrum of ultraviolet and visible rays of a solution of silver nanoparticles was studied as a second step in ascertaining the formation of particles and it was found that they are located at the wavelength (430) nm. 31.77, 46.11, and 57.21), respectively. The particles also appeared as clear particles in the scanning electron microscope images. It was found that the solution of silver nanoparticles had a clear inhibitory effect on two types of bacteria, E.coli and P. mirabilis, which amounted to (33,33,32) mm against E.coli bacteria at a concentration of 100% and (5.6,5 mm) against three E.coli isolates and was (35,35,34) mm at a concentration of 100% against P. Mirabilis
