Researchers find genes linked to development of active TB.

By Dr Deepu
Researchers in Seattle and South Africa have identified markers in the blood of infected people that may predict those at high risk for developing an active  and potentially fatal form of the disease.

A signature pattern of 16 genes, detected in analysis of samples from more than 6,000 South African adolescents, may one day help create a test to identify and treat people likely to develop active TB  more than a year before they get sick.
