Mobile Phones as Reservoirs of Microorganisms: A Study among Medical Students
Year: 2025
Type: article
Abstract: : Background: Mobile phones are indispensable tools for communication and learning, particularly among medical students. However, frequent handling and exposure to various environments make them potential reservoirs for microorganisms, including pathogenic and antibiotic-resistant species. Objective: To isolate, identify, and characterize microorganisms present on mobile phones used by medical students.Methods: Swab samples from 50 mobile phones were collected and cultured on nutrient-rich and selective agar media. Bacterial and fungal isolates were identified using Gram staining and standard biochemical tests. Colony characteristics, hemolytic patterns, and pigment production were recorded. Results: A diverse range of bacteria and fungi were isolated, including Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis, Candida albicans, Aspergillus niger, and Penicillium spp. Several isolates exhibited features associated with pathogenicity, and some were suggestive of antibiotic resistance (e.g., MRSA). Conclusion: The study highlights the role of mobile phones as potential fomites in healthcare environments, emphasizing the urgent need for regular disinfection and strict hand hygiene practices among medical students to reduce cross-contamination and nosocomial infection risks.
