Diagnostics for viruses a step closer to reality
Scientists have developed a technique which could form the basis of a non-invasive diagnostic for Adenovirus – a virus responsible for a large number of common illnesses. The biosensor technology developed by researchers at the University of Leeds can not only detect the presence of the virus, it can also identify the individual strain and the number of virus particles present. Currently, testing for viruses is complicated, time consuming and requires specialist preparation of samples to identify virus DNA. Using this new technique, testing for viruses could be much quicker, simpler and ultimately less costly. Adenovirus is a common virus found in vertebrates and causes many illnesses, from the common cold through to gastroenteritis. People with strong immune systems are not badly affected by the virus, but for those with a compromised or immature immune system - such as small children or HIV sufferers– it can have fatal consequences.
