Tuberculosis :: Health, Diseases

terbium (TB) is an infection that can attack any part of the body, but it is commonly found in the lungs (Huether, McCance, Brashers and Rote, 2008,). TB is an infection caused by a acid-fast bacillus also know as Mycobacterium tuberculosis (Huether et al. 2008) It is oneness of the leading causes of death in Asia, China, Indian, Indonesia and Pakistan (Huether et al. 2008). These countries show that in most cases the incidence rate is highest in young adults, and are usually the result from re-infection in recent infections. The spread of TB is attributed to the emigration of infected people from high-prevalent countries, heart abuse, poverty, transmission in crowd places, and the lack of proper medical direction for the infected individuals (Huether et al. 2008).Tuberculosis is transmitted from person to person finished mobile droplets, when a person that is infected with TB coughs, sneezes, talks, and/or sings letting piddling droplet to be released into the air(Bare, Sme ltzer, Hinkle, and Cheever, 2008). TB cannot be spread through touching non-living objects, food, or drinks (Bare et al. 2008). The person must be in the same field of operations an affected individual is in and inspirate the droplets to be affected. Once the bacillus is shake up into the lungs, the bacilli start to multiply causing lung inflammation also known as nonspecific pneumontis (Huether et al. 2008). To cause an immune response the bacilli will travel through lymphatic system and conk lodged in the lymph nodes (Huether et al. 2008). Lung inflammation causes the activation of the dental macrophages and neutrophils (Huether et al. 2008). Granulomas, new tissue masses of watch and dead bacilli, are meet by macrophages, which mastermind a protective wall. They then transform into a fibrous tissue mass, the central portion is called a ghon tubercle (Bare et al. 2008). The bacteriuml then necrotic, forming a cheesy mass, this mass may become calcified and form a collageno us scar (Bare et al. 2008). At this point, the bacteria becomes dormant and on that point is no further progression of the active disease. The disease can become active again by re-infection or activation of the dormant bacteria (Bare et al. 2008).TB can be classified as latent or active (Bare et al. 2008). TB that is a latent is bacilli that are isolated with a tubercle can remain, dormant, causing no symptoms. Active TB occurs when live bacilli escape into the bronchi or if the immune system is weaken by diseases such as HIV or Cancer (Bare et al.
