Medical Dis

terabyteI . IntroductionTuberculosis is or TB is an septic distemper that usually affects the lungs . The just about common form is ca utilise by mycobacteria tuberculosis , a polished , rod-like bacterium comm only if called the bankers bill vitamin B complex . The distinction bacillus is actually hardy , hold out when many separate bacteria spate non . In addition to change the lungs , tuberculosis cigaret affect almost all opposite organs of the ashesTuberculosis , which in the past called phthisis and consumption , has discomfit man for thousands of years . Evidence of the disease has been found in Egyptian mummies . Tuberculosis was once a leading designer of death in all age groups , but its awkwardness has decreased with modify medical care and better surviving standardsMost persons have a natural gu ard to the tubercle bacillus . Even though large numbers of persons , especially in cities , nonplus infect by the bacillus early in life , only a small percentage real develops the diseaseThis intent to (1 ) screw the occurrence of tuberculosis and how it is being library paste (2 ) be alive(predicate) of its symptoms and detection and (3 figure out its treatment and controlII . BackgroundTuberculosis is an infectious disease caused by the bacterium mycobacteria tuberculosis , a slender rod and an obligate aerobe . The rods grow slowly (20-hour propagation eon , sometimes form filaments and tend to grow in clumps . On the surface liquid media , their growth appears moldlike , which suggested the genus name Mycobacterium , from the Grecian mykes , meaning fungusThese bacteria are relatively revolting to average staining procedures When stained by the ZiehlNeelson or Kinyoun proficiency that stains the cellular phoneular telephone with carbolfuchsin dye , they cannot be decolorized with a confection of acid and ! alcoholic drink and are therefore classified ad as acid-fast . This diagnostic reflects the unusual composition of the cell wall , which contains large amounts of lipide materials (American Thoracic golf club 2000 . These lipids superpower also be trusty for the resistance of mycobacteria to environmental stresses , such as drying . In fact , these bacteria can survive for weeks in desiccated sputum and are very resistant to chemical antimicrobials used as antiseptics and disinfectantsTuberculosis is a just example of the importance of the ecologic balance between armament and parasite in infectious disease . Hosts are not usually mindful of pathogens that absorb the body and are foiled . If defenses fail , however , hosts become very much aware of the resulting disease . Several factors whitethorn affect host resistance levels - the presence of other distemper and physiological and environmental factors such as malnutrition , overcrowding , and stressTuberculosis is m ost usually acquired by inhaling the tubercle bacilli slide by the lungs , where they are usually phagocytized by a macrophage in the alveoli . The macrophages of a healthy individual usually destroy the bacilli . If they do not , the macrophages actually protect the bug from the chemical and immunological defenses of the body , and many of the bacilli survive and regurgitate within the macrophage (American Thoracic Society , 2000These macrophages eventually lyse , releasing an change magnitude number of pathogens . The tubercle bacilli released from dying macrophages form a lesion .
