Mobile phones are
increasingly being used by health care workers in day today life. They
come incontact with various surfaces while carrying out health care
activities and are thus likely to get contaminated by variety of
organisms. This study was carried out to know the microbial flora
harboured by mobile phones of health care personnel and to know the
antibiotic resistance patterns of pathogenic bacteria.
Mobile phones of
health care personnel were swabbed and inoculated on enriched and
selective media, incubated for 24 hours and a variety of biochemical
tests were carried out to know the bacterial and fungal species.
Antibiotic sensitivity tests were done for pathogenic bacteria using K
irby Bauer disc diffusion method. It was found that out of 120 mobile
phones of health care personnel, 99 (82.5%) were contaminated, while 85
(70.8%) harbored pathogenic bacteria. Out of 120 mobile phones; 65
(54.16%) harbored S. aureus, 25 (20.83%) Micrococci, 9(7.5%)
Diphtheroids, 5 (4.1%) Enterococci, [4 (3.3%) each] Pseudomonas,
Citrobacter and Bacillus, [2(1.6%) each] Acinetobacter, Enterobacter and
Streptococcus viridians. S. aureus was resistant to methicillin,
amoxicillin, augmentin, erythromycin and lincomycin. [11/65 (16.9%)]
Methicillin Resistant Staphylococcus Aureus were isolated from health
care providers. Fungi isolated were Candida 8 (6.66%), Aspegillus 6
(5%), Mucor 1 (0.8%) and Trichophyton 1 (0.8%).
