A study was carried out between December and January 2013–2014. To identify bacteria associatedwith mobile cell phones in a Hospital environment. This was with a view to determining the bacterial load andtheir susceptibility pattern to some commonly–used antibiotics. Samples were collected from mobile cell phonesof staff, marketers and students in Khyber Teaching hospital Peshawar using aseptic swab technique. A totalof thirty–five mobile phones were randomly sampled from the following study groups: 10 University staff,12 marketers and 13 students. For each mobile phone, two sterile swabs moistened with normal saline wererotated over the surface of both sides of the mobile phone and soaked in 10 ml peptone water. Bacteria werecounted using pour–plate technique while the bacterial isolates were identified using morphological andbiochemical techniques. The results showed that marketers, students and University staff had the overall mean aerobic mesophilic bacterial counts of 5.25 x 102, 4.48 x 102 and 2.50 x 102 cfu\ml respectively. Twenty–eight bacterial isolates belonging to four genera: Escherichia coli 7(25.0%), Staphylococcus aurous 15(53.6%), Salmonella species 2(7.1%) and Klebsiella species 4(14.3%) were identified. Generally, S. aurous was the mostisolated with 15(53.6%) while the least was Salmonella species with only 2(7.1%). Antibiotic susceptibility testing of the isolates indicated that S. aurous species had the highest susceptibility of 14(93.3%) against cipfloxacin while Salmonella species had 1(50.0%) against augmentin whereas Klebsiella species had 1(25.0%) each against gentamycin and streptomycin. On the other hand, Salmonella species was not susceptible to gentamycin, perfloxacin and streptomycin each with 0(0.0%). Overall susceptibility was highest against ciprofloxacin with 24(85.7%) while the least was recorded against gentamycin with 6(21.4%). The identified bacteria have pathogenic potential and hence their presence on the cell phones surfaces could serve as asource of cross–transmission of bacterial infections in the Hospital and its environment.
