Abstract
Objective: To detect and identify coliform bacteria and other pathogenic microorganisms on mobile phone surfaces of undergraduate students, and to evaluate mobile phone hygiene behaviours and hand hygiene practices that may influence contamination risk.
Methods: A cross-sectional study was conducted among 50 students at Assam down town University, Guwahati, India (March–May 2026). Sterile swabs were collected aseptically from five surface areas of each phone (screen, sides, back, buttons, and camera zone) and inoculated into nutrient broth, followed by subculture on MacConkey agar and Blood agar (37°C, 24–48 hours). Isolates were identified by colony morphology, Gram staining, and a standard biochemical panel including IMViC reactions (Indole, Methyl Red, Voges–Proskauer, Citrate), Triple Sugar Iron agar, Catalase, and Coagulase tests. A concurrent 50-respondent structured questionnaire assessed hygiene behaviours. Descriptive statistics were applied.
