Among these nanomaterials are zinc oxides, titanium oxides, copper, cobalt, silver and gold.<strong>Objectives</strong>:&nbsp;The study of effect of nanoparticles on the gene expression of some swarming genes in Proteus mirabilis bacteria.<strong>Methods</strong>:&nbsp;A total of 30 samples collected from urinary tract infections and wounds in sterile containers in different hospitals in Baquba city (Baquba Teaching Hospital and Al-Batool Hospital) were subjected to Molecular detection about <em>wos</em>A and <em>rsb</em>A genes and Detecting the effect of nanoparticles on gene expression of gene <em>wos</em>A and <em>rsb</em>A<strong> .</strong></p> <p><strong>Results</strong>:&nbsp;Twenty isolates were obtained, all of which had <em>wos</em>A and <em>rsb</em>A genes . Two isolates of urine and burns were selected to determine the effect of nanomaterials on gene expression of the wosA and rsbA genes encoding for swarming. The results of the test of the effect of silver and zinc oxide nanoparticles on the expression of the <em>rsb</em>A and <em>wos</em>A genes responsible for the phenomenon of swarming showed a decrease in gene expression for isolates after treatment compared to pre-treatment gene expression and by 1 before treatment and 0.44 after treatment for the <em>rsb</em>A gene, while for <em>wos</em>A gene, the gene expression of isolates decreased, as the expression before treatment 1 decreased to 0.76 after treatment with nanomaterial.</p> <p><strong>Conclusion</strong>:&nbsp;Isolates of <em>Proteus mirabilis</em> bacteria, which have virulence factors, it causes many diseases and susceptible to infection through their ability to move, transfer, adhere, and form a biofilm.</p&gt;}, number={3}, journal={Central Asian Journal of Medical and Natural Science}, author={Ibraheem M.
