Principles of Respiratory Diseases - Tuberculosis a Brief Study

Tuberculosis (TB) is one of the worst lung infections caused by bacteria called Mycobacterium tuberculosis. It is a disease that can be controlled in cases where it is quickly identified and treated. As sputum microscopy is a simple and low-cost approach, most countries use this technique as an initial step in the diagnosis of TB. For this, the patients' morning sputum is collected and submitted to the Ziehl Neelsen staining procedure before the examination. Then a digital microscope is used, where the images of the sputum slides can be recorded for analysis. In this context, numerous research projects have been developed in the field of computer-aided detection of mycobacteria for pulmonary tuberculosis. The survey of these works was discussed here in this work, as well as their limitations.
