Infections Streptococcal Infections Fasciitis Fasciitis, Necrotizing Genetic Predisposition to Disease
This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.

Invasive bacterial infection is a dangerous but relatively uncommon disease where bacteria spread deep into the body causing diseases like blood poisoning ('bacteraemia'), pneumonia, meningitis and others. The various bacteria of the streptococcus family are an important cause, often leading patients to require intensive care despite which, for some strains, one in five patients die. One notable form is called necrotising fasciitis, a condition where bacteria rapidly spreads through and destroys the layers of tissue just under the skin.
As individuals vary greatly in their risk of developing such serious infections, investigating how the genome, the inherited blueprint of our bodies, of these patients differs from that of healthy volunteers can help to explain why the disease develops in some and not others. For some streptococcal bacteria such as Streptococcus pneumoniae this approach is already proving successful; for others such as the "Group A" strain (Streptococcus pyogenes) it has yet to be explored but carries excellent potential.
The investigators have secured the support of the Lee Spark Necrotising Fasciitis Foundation to recruit from their membership survivors of streptococcal infections and some of their family members. The investigators will also ask infection specialists from NHS hospitals to invite patients they have looked after. The investigators also have a small existing collection. Taking part would involve registering information on a website, discussing the study on the telephone and then providing us with a sample of saliva from which the investigators can isolate DNA. The investigators would prepare the sample for analysis of the genome and compare the patients with both their family and an existing reference collection from healthy volunteers using technology that reads the DNA code.
Our study will be a first key step in renewing efforts to understand the determinants of invasive streptococcal infection, which is important for developing better treatments and vaccines.
