Tuberculosis in children

A lab study found rats can detect tuberculosis in children more effective than the commonly used standard microscopy tests. Generally, TB is very difficult to test for in kids.

The study conducted by Sokoine University of Agriculture in Tanzania, said, when given samples of children’s saliva sniff, rodents detected 68% more cases of TB infections than a simple microscopic.

The incentive for the study comes from narrative conformation that those with tuberculosis (TB) emit a high-specific odor. The new finding is the solid proof that the cheap swab test needs a long-awaited refresh.

Standard microscopy tests

The microscopy test has always offered mixed outcomes, though it is one of the standard treatments around the world.

Lead author Georgies Mgode, said, children with TB are not bacteriological confirmed or even diagnosed, at that point has significant implications for their possible successful treatment.

In some countries, the microscopy test is the first-line strategy because it is so cheap. While, TB is steadily declining in the most part of the US. At the same time, the rates are rising in Asia and Africa.

There is a need for new diagnostic tests to better detect TB in children, particularly in low and middle-income countries.

In this way, researchers examined samples of 982 children who are tested for tuberculosis using smear tests. The smear tests expose 34 children had the disease.

However, when given training to rats to sniff, 57 tuberculosis cases in the samples found. The rats trained to get the scent of TB-causing bacteria in saliva, much similarly trained rats to get the scent of landmines.

This intervention involving TB screening by trained rats and community-based patient tracking of new TB patients missed by hospitals enables the treatment start of up to 70%. This significant extent given that these patients viewed as TB negative in hospitals, hence initially left untreated.
