Dr Takeshi Sasahara is an Assistant Professor at the Kitasato University School of Medicine. He belongs to the Department of Microbiology and Parasitology. His speciality is Environmental Microbiology and Infection Immunology. He has made numerous presentations and papers on his research at the Japanese Association for Infectious Diseases and the Japanese Society of Chemotherapy.

He has investigated the bactericidal activity of copper and its alloys in the hospital environment. Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa were killed when grown on the surface of copper alloys, depending on the incubation period, with P aeruginosa being the most sensitive. Japanese coins made of nickel silver, cupronickel, bronze and brass also inhibited the growth of these bacteria on nutrient agar.

On the basis of these results, a clinical trial was started to monitor the level of contamination by nosocomia bacteria on the surface of copper alloys in the Dematology Ward and Neonatal Intensive Care Unit of Kitasato University Hospital from 2005. It was found that copper alloys had a superior sanitising effect in the hospital environment.

Dr Jean-Yves Maillard's research focuses on microbicides, an area of global importance due to the rise in healthcare-associated infections and emerging microbial resistance. Among his many research activities in this field, his group is developing an antimicrobial surface efficacy test, based on real conditions found in the hospital environment, to quantify the activity of a range of antimicrobial surfaces - including copper - against major pathogens including methicillin-resistant Staphylococcus aureus and Clostridium difficile.  The work aims to provide an easy to use, cost effective and repeatable methodology for healthcare services to distinguish the activity of different commercially-available antimicrobial surfaces. this particular work is being funded by the Department of Health.  Dr Maillard is also on the British Standards Institute committee working to develop a suitable test for antimicrobial hard surfaces.

General research interests are in microbe-metal interactions. For all life there is an absolute requirement for a number of trace element metals.

General research interests are in microbe-metal interactions. For all life there is an absolute requirement for a number of trace element metals. While these metals are needed in low concentrations for growth, the same metals become easily toxic when in excess. One focus of his research is concerned with the mode-of-antimicrobial action exerted by metallic copper surfaces.

Dr Schmidt is Professor and Vice Chairman of the Department of Microbiology and Immunology with research interests in bacterial protein export, molecular pathogenesis, biodefense preparedness, biofilm development and succession, environmental microbiology and most recently the role the inherent microbial burden associated with objects from the built environment plays in the acquisition of Hospital Acquired Infections (HAIs). In concert with colleagues from the Infectious Disease Division of MUSC, the Ralph H. Johnson VA Medical Center of Charleston, Memorial Sloan Kettering Cancer Center and the Copper Development Association, Dr Schmidt is investigating the relationship that the inherent microbial burden plays in conferring a risk that a patient will either be colonised or develop an infection from the microbes associated with the objects encountered as a result of routine care while in hospital.

In the preliminary phase of the African Health Care Initiative, a team of specialist scientists from the University of Stellenbosch, led by internationally renowned Infection Control Specialist, Professor Shaheen Mehtar, proved for the first time internationally via in vitro testing of clinical strains that copper touch surfaces are effective in killing multi-drug resistant bacteria including tuberculosis.

These very exciting observations are now being followed up in South Africa via testing in a real clinic environment. Professor Mehtar's team will be documenting copper's biostatic abilities in both a copper fitted TB 'cough room' at a provincial hospital and at a copper fitted rural health clinic. The learning from these first phase clinical trials will be carried through to a second phase of some 12 clinics across some 6 Southern African countries.

Miedź i jej stopy są materiałami inżynierskimi o dużej wytrzymałości, bogatej kolorystyce, nadającymi się do ponownego przetwarzania. Metale te są ogólnie dostępne w postaci całej gamy półproduktów przeznaczonych do produkcji różnorodnych wyrobów gotowych. Miedź i jej stopy stanowią atrakcyjny zestaw materiałów dla projektantów tworzących funkcjonalne, ekologiczne i przystępne cenowo produkty.

Czysta miedź oraz niektóre jej stopy (określane wspólnym mianem Miedzi Przeciwdrobnoustrojowej) posiadają naturalne właściwości przeciwdrobnoustrojowe, a produkty z nich wykonane zyskują dodatkową funkcję, nie związaną z ich pierwotnym przeznaczeniem - służą podniesieniu poziomu higieny. Wyroby z Miedzi Przeciwdrobnoustrojowej stanowią uzupełnienie, a nie substytut standardowych praktyk kontroli zakażeń. Niezbędne jest przestrzeganie istniejących procedur w zakresie utrzymania higieny, włączając w to procedury czyszczenia i dezynfekcji powierzchni zmywalnych.
