چکیده
Abstract Background: The use of mobile phone by clinical staffs enhances transmission of pathogens and therefore the hardship of interrupting infection spread might be intensified. Objectives: The aim of this study was determined bacterial colonization on the mobile phones used by clinical staffs in hospitals. Materials and Methods: A total of 250 mobile phones randomly sampled from the users of these phones were examined. The phones were obtained from the following study groups: Group A, 125 clinical staffs including physicians, nurses, residents, and interns; and group B, 125 university headquarters staffs. Isolated microorganisms were identified using biochemical tests such as gram stain, morphology, catalase, and oxidase reaction, and all isolates were allocated to appropriate genera. Antibiotic sensitivity was done using the Kirby- Bauer disc diffusion method. Results: In total, 99.2% of mobile phones in clinical staffs group demonstrated growth of bacterial species that the most common isolate was coagulase-negative staphylococci (82.4%), followed by Staphylococcus aureus (20.0%) and Pseudomonas aeroginosa (12.0%). Among controls, 93.6% of mobile phones demonstrated growth of bacterial species. For eradication of coagulase-negative staphylococci, the highest resistance rate was detected to Oxacillin and for inhibition of Staphylococcus aureus, the highest resistance was detected to Oxacillin. For eradicating Pseudomonas aeroginosa, considerable resistance rate to Ampicillin were detected in both study groups. Conclusions: Mobiles contamination with different pathogens is extremely common among our healthcare staffs compared with other societies, and resistant of these isolates to various antibiotics is also detectable. Thus, quick assessment of this issue to prevent the spread of this infection agents is critical for the authorities in our healthcare systems.
