Abstract: Ninety eight mobile samples, (54) galaxy phone and (44) I phone, were swabbed for bacterial culture determination by culturing on MacConky agar, Blood agar, Mannitol salt agar, Muller Hinton agar. Staphylococcus was the highest frequent isolated bacteria from Galaxy phone (33 %) and I phone (37 %). This study revealed that galaxy phone appears less contaminated with bacteria, the ratio of non-contaminated devices is (44 %) when compared with I phone (9 %). Sensitivity test showed that Ogmintin have the lowest effect on Staphylococcus isolated from both type of devices while cefitriaxone have the highest effect. DNA of isolate from galaxy 31 that exhibit highest resistance against antibiotics was extracted and 16S rRNA gene was polymerized by PCR and sequenced by microgen company, the result identified as Staphylococcus aureus.
