New Delhi, 17 September (IANS). According to a study, in place of the currently used sputum test, soon the simple tongue will be possible to check tuberculosis.
Researchers at the University of Tulalen, USA said that the community-based screening of the world’s most deadly infectious disease can be easier by using advanced CRISPR-based technology.
Jane Huang, assistant professor and leading writer at Tulen’s School of Medicine, said that a practical tuberculosis tongue Swab test could benefit communities with less resources.
Huang said, “Tung (tongue) swabs are painless, it is easy to collect, and it does not require trained medical staff. This opens the way of screening on a large scale.”
Currently TB test is dependent on spit, which is a mucus collected from the lungs and lower respiratory tract.
In cases of about 25 percent symptoms and about 90 percent of symptomatic cases, it is not only difficult to collect sputum, but also impractical – due to this, estimated cases of 40 million tuberculosis are not diagnosed every year.
The study published in Nature Communications magazine attempted to reduce the gap of earlier CRISPR-based tests.
The new RISPR method called ActCRISPR-TB helped understand genetic signals from DNA of TB bacteria. This provided a streamlined approach to diagnose in less than an hour.
Clinical testing showed that TB from tongue swab is easier to detect than traditional testing. Earlier, where its rate was 56 percent, now it has increased to 74 percent.
This test has achieved great success in detecting TB from respiratory (93 percent), pediatric stool (83 percent), and adult spinal fluid samples (93 percent).
