Device focuses on speedier tuberculosis diagnosis

A device that can magnify tuberculosis bacteria without using a conventional glass lens could soon replace expensive lens-based microscopes in developing countries, according to a feasibility study published in the journal Tuberculosis.The gadget could diagnose tuberculosis in a sample within seven days, while also reducing the danger of lab technicians catching the disease, the researchers say. The microscope is connected to a computer using software that captures the patterns formed by suspected tuberculosis bacteria in a special petri dish.The new device automatically takes photos of samples in a sealed petri dish using an LED light and electronic sensor.
