This study was conducted to isolate and identify bacteria contaminants on a mobile phone. The samples were collected randomly from 20 mobile phones. This study was conducted between October to December, 2016 at College of Biotechnology, Al-Nahrain University. The isolated colonies were then sub cultured in nutrient agar and slants in order to obtain pure culture of all the six colonies. Six genera of bacteria were identified from positive cultures. In all, 20 swab samples of mobile phone were randomly examined, 19 bacterial isolates were identified from mobile phones were found contaminated with microbiota. The highest prevalence of Staphylococcus aureus was observed in mobile phones. The research findings indicated that S. aureus (8 isolates), Escherichia coli (4 isolates), Enterobacter spp (2 isolates), Bacillus (1 isolates ), Streptococceus spp (1 isolates), and Pseudomonas spp (3 isolates), were the main isolates frequently associated with the mobile phones. Showed Percentage of bacterial isolates from the samples collected from mobile phones after calculating the total percentage of each isolate, found S. aureus, E. coli, Enterobacter spp, Bacillus, Streptococceus spp and Pseudomonas spp in the percentage of 42.10 %, 21.05 %, 10.52%, 5.26 %, 5.26 % and 15.78 % respectively. The results showed that mobile phones were contaminated with different types of bacteria mentioned above. Gram positive cocci, Streptococcus and Staphylococcus spp. were identified based on morphological characteristics. Gram negative bacilli, E. coli, Enterobacter, Bacillus and Pseudomonas were identified based on morphological characteristics. Nineteen isolates from 20 observed mobile phones belonging to the students. The highest prevalence in male was (13 isolates) and were percentage of bacteria isolated 66.66%, while in female were (6 isolates) and percentage of bacteria isolated 33.33%. Also showed results Percentage of total bacteria isolated of female and male, were 31.57% and 68.42 % respectively.Downloads
