ABSTRACT

Cell phones can act as a potential microbiological threat, serving as vehicles to transfer contamination from one place to another. The aim of this study was therefore to isolate, identify and to detect the contamination rate of cell phones surfaces with microorganisms among the cell phones of Students, Butchers and Food handlers. The samples were collected using sterile swab stick moistened in sterile peptone water. The bacteria colony counts was carried out using pour plate technique while the bacteria isolate were identified using cultural, morphological and biochemical techniques. The results showed that Students, butchers and Food handlers had the overall mean bacterial counts of 2.1 x 103, 3.1 x 103 and 3.2 x 103 cfu/ml respectively. Fifty-Nine (59) bacterial isolates belonging to four genera: Staphylococcus aureus 38(63.3%), E. coli 11(18.3%), Salmonella species 6(10%) and Klebsiella species 5(8.3%) were identified. Generally, Staphylococcus aureus was the most isolated with 38(63.3%) while the least isolated was Klebsiella species with 5(8.3%). The frequency of occurrence of the isolates indicates that Staphylococcus aureus had the highest frequency of occurrence in both the Students, Butchers and Food handlers while Klebsiella species had the lowest frequency of occurrence. Some of the cell phones examined had potential disease causing bacteria, this results highlight the health implications of using other people`s cell phones as they could be loaded with bacteria and other microbes capable of causing various infections.
