Inanimate common objects touched by people (toys,
computer keyboards, door knobs, etc) may transmit
bacterial infections particularly in hospitals as well
as in the community.
Recently the number of rent a car agencies as well
as DVD rental shops has increased tremendously all
over the country particularly in the main cities of
Libya (Tripoli and Benghazi).
The aim of the present work was to isolate and
identify the bacteria from the surfaces of steering
wheels of rented cars and rented DVDs and
determine the susceptibility of the isolated bacteria
Using sterile moistened swabs two samples were obtained
from each steering wheel (SW) of 30 cars (20 rented) and from
60 rented DVDs.
Samples were plated on Mannitol Salt agar for isolation of
staphylococci, MacConkey agar and Salmonella-Shigella agar
(SSA) for salmonellae, shigellae and other enterobacteria,
Blood agar for streptoccoci and Pseudomonas spp., and
inoculated into Selenite F broth (SF) and Alkaline Peptone
water (APW, pH 8.6, enrichment for Aeromonas). After
overnight incubation at 37°C, loopsful from SF and APW were
plated on SSA and BA supplemented with 15mg ampicillin,
Suspected colonies were identified using standard
bacteriological procedures and API 20NE whenever
Susceptibility of isolated organisms to antibiotics was carried
out by the disc diffusion method.
How we can make a bug’s life on
SW and DVD hard?
Wash hands with soap and running water
after using a rented car and/or DVD
Disinfect SWs and DVDs before use with
– MediSawbs, Sterets, others.
Designing surfaces that kill bacteria on
– Amino glass slides acylated with acryloyl
chloride, copolymerized with 4-vinylpyridine,
and N-alkylated with different alkyl bromides
(porpyl to hexadecyl).
– The resultant surfaces, depending on the
alkyl group were able to kill up to 94 + 4% of
S. aureus cells sprayed on them.
