Detection of the ability of some types of cyanobacteria to the production of antibiotics and studying the portability of these antibiotics in the inhibition of multidrug resistance bacteria

Abstract EN

The present study was carried out to detect the susceptibility of some types of cyanobacteria to the production of antibiotics and the ability of these antibiotics to inhibit the bacteria known for their multiple resistance to other antibiotics.

Collected about 150 soil samples from five different governorates (Diwaniyah, Babel, Wasit, Baghdad and Basra), specifically from the soils near the Tigris and Euphrates rivers and for the period from 1/5/2016 to 1/5/2017.

After implantation of the samples and sensitivity test using the disk diffusion method,the results yielded different inhibit- ion zones, ranging from 12.3 to 4.5, It also revealed the species of the growing cyanobacteria, which gave the largest inhibition zones and it was noted that most of them belong to three common types in Iraq Microcystis aeruginosa, Anabaena variabilis and Hapalosiphon aureus.In addition to 47 other species not disclosed in this study.
