The College of Education for Pure Sciences in the Department of Life Sciences at the University of Basrah  discussed a doctoral thesis on (using some bacterial species isolated from the marine environment in the biosynthesis of silver nanoparticles and testing their effectiveness against pathogenic bacteria)
The thesis presented by researcher (Fadel Jabbar Farhan) included the current study isolating some bacterial species from Iraqi marine waters, using their extracellular metabolic products for the purpose of biosynthesis of silver nanoparticles, and studying the antibacterial effectiveness of these nanoparticles against pathogenic bacteria with multiple resistance to antibiotics.
I dealt with the thesis
There are three types of marine bacteria capable of manufacturing silver nanoparticles, and the physical and chemical properties of these nanoparticles were studied
It included the visible light spectrum - ultraviolet rays,
These silver nanoparticles were effective against antibiotic-resistant pathogenic bacteria. It also contributed effectively to enhancing the effectiveness of antibiotics against pathogenic bacteria by adding them to antibiotic tablets. After testing the effect of mixing silver nanoparticles with some antibiotics in such a way that the minimum inhibitory concentration values of the antibiotics were significantly reduced against pathogenic bacteria,
The thesis was concluded
The possibility of biomanufacturing silver nanoparticles using bacteria isolated from Iraqi marine waters in a simple and inexpensive way compared to other methods. They have good stability, and that these nanoparticles are effective against antibiotic-resistant pathogenic bacteria, and they have effectively contributed to increasing the inhibitory effectiveness of some antibiotics against pathogenic bacteria, so it is possible to use them to enhance the effectiveness and improve the efficiency of antibiotics against pathogenic bacteria, so they can Its use in treating external infections caused by pathogenic bacteria resistant to antibiotics.
