| dc.description.abstract | Mobile phones are increasingly used by professionals university staff and health care
professionals for communication these may harbor in various potential pathogens. The
ability of the microbes to survive on the surface of mobile phone makes it as one of the
important fomites in the spread of microorganism between users. Present study was
designed to isolate and identify of bacteria from mobile phones of students and
employees of Hajee Mohammad Danesh Science and Technology University Dinajpur,
Bangladesh. A total of 32 swab samples of mobile phones were collected in different
academic staffs, nonacademic staffs, students and cleaners. In this study bacteria were
identified on the basis of morphological, cultural and biochemical characterization. The
total viable count (TVC) of different swab samples of mobile phone in different
categories (academics, nonacademic, students and cleaners) were studied. samples were
ranged from 73×10-6 CFU/ml to 260×10-6 CFU/ml. Among 32 swab samples the bacterial
percentage isolation frequency and occurrence were Staphylococcus spp 21 (25.6%),
Bacillus spp 17(20.7%), Klebsiella spp 16(19.5%), Pseudomonas spp 15(18%) and
Salmonella spp 13(15.85%). The vitro antibiotic sensitivity test of isolated bacteria
Staphylococcus spp, Bacillus spp, Klebsiella spp, Pseudomonas spp and Salmonella spp
were resistance in randomly Penicillin, Amoxicillin, Cefaclor, Ofloxacin and
Ciprofloxacin.
The finding of this research indicates that all mobile phones under consideration were
infected by several microbes most of which belongs to the natural flora of the human
body. Therefore sharing of mobiles, usage of mobile during eating should be
discouraged. Personal hand hygiene is very important and also washing of hand before
and after handling phones since it is a source of disease transmission. The purpose of this
study was to investigate microbial colonization on mobile phones and suggested a cost
effective solution for the emerging nosocomial infection. | en_US |
