So, these devices may become contaminated with a variety of bacterial organisms.</span><span cambria= style=font-family:> The aim of this study was to evaluate bacterial contamination and identify all bacterial isolates of mobile phones related to social groups in Kufa Technical Institute and to determine the efficiency of two disinfectants prepared on bacterial species.</span><span style=font-family:Cambria,serif></span></span></span><br> <span style=font-size:10pt><span style=unicode-bidi:embed><span new= roman= style=font-family: times=><b><span cambria= style=font-family:>Materials & Methods:</span></b><span cambria= style=font-family:> Fifty-one swab samples of mobile phones were randomly collected from different people in the social groups of Kufa Technical Institute and cultured on selective and enrichment media and incubated at 37°C for 24 hours. Then, the isolated bacteria were identified by gram staining and biochemical tests and confirmed using Vitek 2. Next, two disinfectants were prepared and their inhibitory activity against microbes compared to ethanol alcohol-70% was investigated.</span></span></span></span><br> <span style=font-size:10pt><span style=unicode-bidi:embed><span new= roman= style=font-family: times=><b><span cambria= style=font-family:>Findings: </span></b><span cambria= style=font-family:>Ten bacterial species were isolated and identified from mobile phones, which included <i>Staphylococcus aureus</i> (49%), <i>Staphylococcus epidermidis</i> (12%), <i>Pseudomonas aeruginosa</i> (11%), <i>Staphylococcus haemolyticus</i> (6%), <i>Escherichia vulner</i> (6%), <i>Escherichia coli</i> (4%), <i>Klebsiella pneumoniae</i> (4%), <i>Bacillus sp</i> (4%),</span> <i><span cambria= style=font-family:>Pantoea spp</span></i><span cambria= style=font-family:> (2%), and <i>Cronobacter C sakazakii</i> (2%).
