Bacterial flora on mobile phones of faculty members
may vary in composition, number and antibiotic sensitivity,
to that found on mobile phones of non-faculty members.
This is probably the first study in Saudi Arabia that
attempts to study the bacterial flora present on the mobile
phones of faculty members and personnel, and to compare
it with that found on mobile phones of personnel in
terms of composition, number and antibiotic sensitivity.
RAPD-PCR is a genotyping system that has shown
great specificity and sensitivity to characterize bacterial
isolates. RAPD system uses short and arbitrary oligonucleotide
random primers under low specificity conditions.
It is less costly and faster and easier to per-form
than analogous systems, and do not require prior knowledge
of a DNA sequence. It is efficient enough in developing
a large number of DNA markers in a short time
and requirement for less sophisticated equipment
