Latest Technology To Detect Resistant Tb Bacteria Developed

London: Scientists have developed a new technique to detect tuberculosis bacteria which endure the treatment, paving the way for effectively treating TB bacilli resistant to antibodies.

Researchers from the Antwerp Institute of Tropical Medicine have created a easy technique of Fluorescein diacetate staining, which only stains living tuberculosis bacilli (and not dead ones) which can immediately tell if resistant bacilli survived after treatment.

Tuberculosis bacilli have turn out to be resistant against major antibiotics. According to World Health Organization (WHO) survey, only 11 per cent of multiresistant cases were discovered in 2009.

Checking quick under the microscope still is the recommended technique for TB screening, but it cannot differentiate between living and dead bacilli.

It is therefore not clear whether you are looking at the cadavers of a successful treatment, or at anti survivors. Only if the numbers after a long wait still don't fall, you know you are dealing with a anti strain. But all that time.

Innovative Technology Detecting Radioactive Material

Researchers at the Georgia Tech Research Institute (GTRI) have generated a new prototype radiation detection device for use at ports, border crossings, airports and elsewhere.

Using new materials and nanotechnology techniques, they've developed the Nano-photonic Composite Scintillation Detector, which combines rare-earth elements and other materials at the nanoscale to improve sensitivity, accuracy and robustness.

The co-principal researcher Bernd Kahn said that, “US security personnel have to be on guard against two types of nuclear attack - true nuclear bombs, and devices that seek to harm people by dispersing radioactive material and both of these threats can be successfully detected by the right technology."

There are currently two common types of radiation detectors: scintillation detector, which usually employ a single crystal of sodium iodide or a similar material, and solid-state detectors based on semiconducting materials such as germanium.

Both technologies can detect gamma rays and subatomic particles emitted by nuclear material, but have drawbacks. The large sodium iodide crystals required for scintillation detectors are typically fragile, cumbersome, difficult to produce and extremely vulnerable to humidity.
