Introductions
Tuberculosis, or TB, is an infectious ailment caused by bacteria known as Mycobacterium tuberculosis, which commonly affects the lungs (Siegenthaler, 2007). It is a communicable disease that spreads from an individual to another through discharge from the throat and lungs of persons infected with the active respiratory disease.
In healthy people, infections with Mycobacterium tuberculosis often have no symptoms, since the immune systems of an individual keep off the bacteria. The signs of active TB are coughing, sometimes with mucous with blood, chest pains, weakness, weight loss, fever, and night sweats. Tuberculosis is a disease treatable with a six-month use of antibiotics.
TB is a disease that can imitate different diseases. It has been affecting people for many years and the cadavers from 8th Century shows the evidence (WHO, 2010). In the 1900s, TB was the root cause of death in the United States. Robert Koch found the cause of Tuberculosis in 1882 as the bacteria Mycobacterium tuberculosis. The increased understanding of TB and public awareness on treatments like quarantine and drugs for treatment has seen a decrease of the disease in the developed countries.
The Various Kinds of Tuberculosis (TB)
There are different forms of TB; however the leading types are TB that are active or latent. Tuberculosis that is active occurs when the ailment is aggressively showing symptoms and it can spread to other individuals. Latent TB is when, an individual ails from the bacteria Mycobacterium tuberculosis, but the bacteria are not showing signs. This is normally owing to the immune system of the body suppressing the growth of bacteria and its transmission. Individuals with TB that is latent usually cannot transmit Mycobacteria TB bacteria to others except when the immunity of the individual fails; the failure of the immune system can cause the bacteria growth, causing the person to have active TB; so the disease becomes infectious.
Several types of TB exist in either the active or the latent form. The type of TB depends on the signs and symptoms and where the Mycobacterium tuberculosis specially infects, which vary from one individual to another. Subsequently, pulmonary tuberculosis mostly affects the pulmonary system, skin symptoms causes cutaneous TB, while small lesions or granulomas that is widespread in the body organs, is the miliary TB. It is not unusual for some persons to get infected by several types of active TB.
What Are The Causes Tuberculosis?
TB is the infection of human immune system by the bacteria known as Mycobacterium tuberculosis. These bacteria have slow growth, spread on air, and can develop within body cells intracellular parasitic bacteria (WHO, 2010). The bacteria mycobacterium has a unique cell wall that guards it from the body's defenses. The Mycobacteria that escape damage by body immunity may transmit TB through the blood or lymphatic paths to organs like the lungs, kidneys, skin, and bones that oxygenate well. TB granulomas typically consist of an area of necrotic central area. These lesions also have mycobacterium. In infections that are latent, a tough case usually surrounds the granulomas, and in some i...
