Abstract

Smart phones with touch screens are now common place with students today. The microbial density of mobile phone screens of undergraduate students were examined using standard bacteriological methods. The susceptibility of the bacterial isolates was carried out using disc diffusion method. The efficacy of alcohols as a potential phone screen disinfectant was tested on the isolates. Six species of bacteria as well as five (5) species of fungi were isolated. The bacteria genera were Klebsiella spp (60%), Micrococcus spp (60%), Bacillus spp (65%), Staphylococcus spp (85%), Proteus spp (65%) and Escherichia coli (60%). The isolated fungi include Aspergillus Niger, Penicillium spp, Mucor spp, Candida spp and Cladosporium spp. The organisms were generally susceptible to commercially available antibiotics. Among the antibiotics ciprofloxacin (5?g) exhibited the highest zone of inhibition (22mm) on Staphylococcus aureus. (14mm). Isopropyl alcohol and ethyl ethanol at a concentration of 70 % showed 100% elimination of microbial contaminants of phone screens. This study showed that all mobile phones under consideration were infected by several microbes. Hand hygiene and regular phone sanitization with alcohol based products is therefore recommended.
