Abstract

In this study 50 isolates were obtained from the Baghdad teaching city medicine laboratories, from wounds and burns. Isolates were identified exercise VITEK 2 system (Biomerieux). Streptococcus pyogenes isolate was used to create the biosynthesize of silver nanoparticles’’ against some pathogenic microbes such as Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, and Candida albicans. Evaluation of the effect of the created biosynthesis silver nanoparticles’’ (AgNPs) by Streptococcus pyogenes on the biofilm formation by various human pathogenic bacteria.  Biosynthesis of AgNPs was characterized by ultraviolet-visible absorption spectroscopy, the observation of color change of the experimental samples in the presence of 1 mM AgNO3 at 410 nm. A color change from pale yellow to slightly brown occurred for bacterial supernatant within 24 hours of incubation in the presence of light Scanning electron microscope (SEM), the biosynthesis silver nanoparticles’’ are predominately circular fit as a fiddle having a smooth surface and very much scattered with close minimal game plan, X-ray diffraction (XRD). The The normal molecule size was determined by Debye-Scherer equation and its evaluation was roughly 6.43nm. The normal molecule size was determined by Debye-Scherer equation and its evaluation was roughly 6.43nm. The importance of this work lies in the possibility of synthesizing the silver nanoparticles’’ using these bacteria, which are considered as types of fastidious bacteria. As far as the researcher’s knowledge is concerned, this is study is the first of its kind in Iraq.
