Bio trunking has demonstrated effectiveness against:
•
Methicillin resistant Staphylococcus aureus (MRSA): an antibiotic resistant,
opportunist pathogen that can survive on surfaces within the hospital
environment.
•
Klebsiella pneumoniae: an opportunist pathogen affecting people with
a weakened immune system.
•
Streptococcus pyogenes: tonsillitis, scarlet fever, necrotising fasciitis
(the ‘flesh-eating bug’).
•
Vancomycin-resistant Enterococcus faecalis: E.faecalis: a concern when antibiotic
resistance is acquired.
•
Escherichia coli: All of us are colonised by E.coli in our gut but this bacterium
can cause infections if it is transferred to a wound or a different part of the body
causing severe food-associated illness.
•
Pseudomonas aeruginosa: a common bacterium found in water and other
environments and is associated with burns infections, medical device infections
and food spoilage.
•
Acinetobacter baumanii: is associated with HAI and is often resistant to antibiotics.
•
Bacillus subtilis is a spore forming bacterium with the ability to form resistant
spores that cause a problem for cleaning and disinfection.
•
Salmonella: the Salmonella species cause food-borne illness.
•
Legionella: Legionellosis is a severe form of pneumonia caused by inhalation of
infected aerosols, for example via air conditioning systems.
•
Lactobacilli are essentially non-pathogenic: they are often used as probiotics.
Some species cause spoilage, for example in the brewing industry.
•
Corynebacterium pseudodiphtheriticum:, associated with respiratory infection.
The treated curved profile (Sample 2) showed excellent control of both MRSA and Klebsiella Pneumoniae with a greater than 99.9% reduction in bacteria
compared to the untreated flat profile (Sample 1). The bacteria grew on the untreated sample.
White Paper
Joanna Verran is Professor of Microbiology
in the School of Biology, Chemistry and
Health Science at Manchester Metropolitan
University. Her research is interdisciplinary,
involving collaboration with materials
scientists, polymer and dental technologists
and surface engineers focusing on
the interactions occurring between
microorganisms and inert surfaces. In 2008,
Professor Verran wrote a 6-page White Paper
on the effectiveness of silver ion pregnated
antimicrobial trunking for Marshall-Tufflex.
Here are a few extracts from that paper:
“In the hospital environment, patients are
particularly susceptible to infection, thus
reduction in the transfer of microorganisms
directly from person to person and indirectly
via inanimate objects, is a key objective. The
microorganisms present may also be more
resistant to antibiotics.
“… ‘silver ions’ …. exert a bactericidal effect
at very low concentrations. Unlike antibiotics,
which have specific targets present in microbial
cells thus demonstrating ‘selective toxicity’ …
silver, like other biocides, is toxic to multiple
components of bacterial cell metabolism.
These include damage to the bacterial cell wall
and membrane permeability.
“… damage leads to blockage of transport and
enzyme systems, alterations of proteins, …
and binding of microbial nucleic acid, which
prevents protein synthesis and cell division.
“… rapid or sustained release is important …
demonstrated by impregnated surfaces where
the silver is mobile and essentially renewable
to the surface. Coatings might, in contrast, be
lost or exhausted more rapidly.”
