A team of scientists from Stellenbosch University in South Africa have come up with a process that aims to detect Latent Tuberculosis (The most dangerous form of Tuberculosis) at a much more earlier stage, which in turn would help scientists around the world to adequately develop medications that can eradicate this form of Tuberculosis for good.
As we all know, Tuberculosis is a disease that attacks the lungs and the typical Tuberculosis treatment only targets the active bacteria that are growing in the body whilst a small amount of them are able to hide and evade treatment. These troublesome ones are known as Persistent Bacteria and they have the tendency to stay dormant for a long period of time in the body (without showing any symptoms) before finally developing into Latent Tuberculosis and striking when one’s immune system is at it’s weakest.
In 2014, TB killed 1.5 million people and now ranks alongside HIV as the leading cause of death worldwide. Identifying this persistent bacteria has been a tough quest for scientists over the years, but a breakthrough has been reached at last. South African scientists alongside colleagues from Imperial college London have developed a new technique that has never been applied before in Tuberculosis research, so it’s really a ground breaking and innovative process.
The process itself is called fluorescence dilution, and it works by using two fluorescence proteins to label the bacteria, tracking it and measuring its growth so that it can be identified by doctors. This process will prove to be very useful for scientists and medial doctors around the world as it will now accelerate the process of developing a drug that can essentially kill this previously unidentifiable Tuberculosis Bacteria.
