Silver
Resistant bacteria, particularly those that known as MRSA, are an increasing global threat to health and the problem has been exacerbated by the uncontrolled use of antibiotics. Suppliers to the medical profession are now seeking alternative measures to prevent the development of further resistance and manage infections.These include antibacterial preparations and dressings that contain silver.
Metallic silver has been used to prevent the growth of micro-organisms since at least the time of Aristotle, who advised Alexander the Great (335 BC) to store his water in silver vessels and to boil it before use. The remarkable biocidal properties of silver have lead to its inclusion in a wide range of 21st Century products, including clothing, several types of medical devices and particularly many different types of dressings.
Recent research has confirmed that silver products could be used as an alternative to antibiotics to curb the spread of antibiotic-resistant bacteria. It has also been demonstrated that the distribution of the silver throughout the dressing, and the rate at which it is released affects the dressings effectiveness in killing micro-organisms as well as many other factors.
The Laboratory at The Birmingham Assay Office has experience in working with pharmaceutical companies to check the concentration of silver in dressings. The Laboratory regularly tests fabric and polyurethane dressings as part of an overall quality control and due diligence programme for many customers in this field.
