Health-seeking behaviour, health seeking delay, perceived causes, and perceived quality of care related to TB were studied in interviews with sputum smear-positive TB patients. The patients were treated in 22 governmental health centres of Malabon, a municipality of Metro Manila, Philippines.
Scanning electron micrograph of M. In nature, the bacterium can grow only within the cells of a host organism, but M. Since MTB retains certain stains even after being treated with acidic solution, it is classified as an acid-fast bacillus.
The latter two species are classified as " nontuberculous mycobacteria " NTM. Risk factors for tuberculosis A number of factors make people more susceptible to TB infections.
Silicosis increases the risk about fold. These include alcoholism  and diabetes mellitus three-fold increase. Transmission When people with active pulmonary TB cough, sneeze, speak, sing, or spit, they expel infectious aerosol droplets 0.
A single sneeze can release up to 40, droplets. After about two weeks of effective treatment, subjects with nonresistant active infections generally do not remain contagious to others.
During this process, the bacterium is enveloped by the macrophage and stored temporarily in a membrane-bound vesicle called a phagosome.
The phagosome then combines with a lysosome to create a phagolysosome. In the phagolysosome, the cell attempts to use reactive oxygen species and acid to kill the bacterium. The primary site of infection in the lungs, known as the " Ghon focus ", is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe.
This is known as a Simon focus and is typically found in the top of the lung. MacrophagesT lymphocytesB lymphocytesand fibroblasts aggregate to form granulomaswith lymphocytes surrounding the infected macrophages. When other macrophages attack the infected macrophage, they fuse together to form a giant multinucleated cell in the alveolar lumen.
The granuloma may prevent dissemination of the mycobacteria and provide a local environment for interaction of cells of the immune system. Macrophages and dendritic cells in the granulomas are unable to present antigen to lymphocytes; thus the immune response is suppressed.
Another feature of the granulomas is the development of abnormal cell death necrosis in the center of tubercles. To the naked eye, this has the texture of soft, white cheese and is termed caseous necrosis.
Tissue destruction and necrosis are often balanced by healing and fibrosis. During active disease, some of these cavities are joined to the air passages bronchi and this material can be coughed up.Overview.
Tuberculosis (TB) is a potentially serious infectious disease that mainly affects your lungs. The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes. Abstract: SETTING: In Morocco, tuberculosis (TB) treatment default is increasing in some urban areas.
OBJECTIVE: To provide a detailed description of factors that contribute to patient default and solutions from the point of view of health care professionals who participate in TB care. Health seeking and perceived causes of tuberculosis among patients in Manila, Philippines.

[email protected] Inefficient case finding is an important stumbling block to successful control of tuberculosis (TB).
Tuberculosis, TB, consumption, phthisis, Pott’s disease, scrofula, yakshma, chaky oncay, romantic disease, the White Plague.
2 This disease, caused by strains of Mycobacterium tuberculosis, has been known by many names over its long and legendary history. The oldest evidence of TB dates back approximately years. Health-seeking behaviour, health seeking delay, perceived causes, and perceived quality of care related to TB were studied in interviews with sputum smear-positive TB patients.
The patients were treated in 22 governmental health centres of Malabon, a municipality of Metro Manila, Philippines.
The perceived causes (PCs) of leprosy and TB in patients were compared based on prominence categories. The relationship between PCs as predictors, and disease conditions and HS preferences as outcome variables were assessed using multivariate logistic regression.
