Tuberculosis : An Infectious Bacterial Disease

Tuberculosis (TB) is a bacterial infection in which nodules referred to as tubercles grows in the bodies tissues, especially on the lungs. Tuberculosis is a

Tuberculosis is a bacterial infection that can be spread in the lungs, lymph nodes, and bloodstream and to any part of an organ in the body. They are two types of tuberculosis which, is active and

Tuberculosis is a disease caused by Mycobacterium tuberculosis that most commonly affects the lungs. The etiologic agent can be expelled from one infected person via a sneeze or a cough, and enter the air and then the body of another person, leading to another infected person (“Tuberculosis, 2012). According to “What is TB?” (n.d.), someone who has diagnosed tuberculosis but is not receiving any form of treatment can pass the disease to up to 15 people in on year. Treatment of TB is necessary, so if symptoms are ignored, an infected person could die. Prevalence of this disease is not as common in the United States as it is in other countries. In 2014, there were approximately 9,421 reported cases; trends show that TB prevalence continues to decreases each year. Of

I will start with Latent TB which is most commonly known as inactive TB mainly because in this stage you have no symptoms of the disease. The second type of TB is Active TB which is the stage that you will begin to develop symptoms and feel sick. Third type of TB is Pulmonary TB which takes place in the blood and oxygen of the body. Finally the fourth type is Extrapulmonary TB which is when the disease spreads to other parts of the human body to effect different types of organs.

Tuberculosis, commonly referred to as TB or consumption, is a dangerous pathogen caused by mycobacterium tuberculosis (M. tuberculosis). It is the second-highest cause of death, killing off 1.5 million each year. TB victims are normally infected in the lungs by airborne pathogens and fluids, but other organs can be targeted. There are two types of TB: active, in which victims are infectious and show symptoms, and latent, where victims do not show any signs at all, making TB a silent threat that could manifest in the body without warning.

Tuberculosis, a disease caused by the bacteria Mycobacterium tuberculosis, has been around for thousands of years. In fact, one of the earliest cases of tuberculosis, known as TB, or often referred to as the White Plague, because of the pale skin of the Caucasians who wasted away from it, was found in a young man from Germany about 7,000 years ago. Scientists believe tuberculosis was probably an extremely common disease in Ancient Egypt, and throughout the centuries was spread through Europe, Asia, and Africa. European explorers including Columbus, were blamed for bringing TB to the New World, though evidence proves Native Americans suffered from the disease long before then.

Tuberculosis is a chronic necrotizing granulomatous disease/ infection caused by the acid-fast bacillus (AFB) Mycobacterium tuberculosis, a group of rod-shaped organisms, as small as 2 to 4 micrometres. They are known as "acid-fast" bacteria because of their resistance to acid solutions in laboratory tests. Isolating and identifying tuberculosis bacilli was impossible until this attribute was understood and hence gave rise to alternative and new testing techniques. Tuberculosis most commonly attacks targets the lungs, and in cases of extra pulmonary sites, it targets the pleura, bones, lymph nodes and joints.

Tuberculosis (TB) is a chronic bacterial infection that affects millions of people globally. It is a contagious disease that is spread through the air, and it usually affects the lungs. It is transmitted from person to person through droplets from the respiratory tract of those who are already infected with the disease. Some who are infected with the bacteria that causes TB often exhibit no symptoms, because their immune systems stop the bacteria from growing and multiplying. Those with compromised immune systems are more susceptible to developing the full blown disease which can cause symptoms that include coughing, spitting blood, chest pains, weakness, weight loss, and fever. Tuberculosis can be treated with a six to nine month course of a combination of antibiotics. If left untreated, TB will spread and can be fatal.

Tuberculosis is a bacterial infection, this bacterial is called Mycobacterium Tuberculosis. This bacteria can affect any part of the body but most commonly attacks the lungs. Different parts that gets attack are the kidney, spine, and brain. This bacterial infection can be contagious, most commonly spread by having constant contact with a person with the active infection. This infection can be deadly if not treated.

If the patient is suffering from latent TB it means the patient ha mycobacterium Tuberculosis bacterium in his body, but they are inactivated. To treat TB infection it is most important that the patient consults their doctor. Most common medicine used for this type of TB is isoniazid (INH. In most of the cases this medicine would take about 6 months (if taken regularly) to kill all the inactivated bacterium.

TB can be categorized into two different types, according to where it has manifested itself. These two types are described as: Pulmonary Tuberculosis and Non-Pulmonary Tuberculosis.

Tuberculosis is an infectious disease caused by a bacterium called Mycobacterium tuberculosis (Marieb, 2012). Tuberculosis is a contagious infection that begins in the lungs and spread to other organs in the body including the kidneys, brain and bones. Tuberculosis is spread by inhaling airborne droplets from an infected person. These airborne particles are spread when the infected person sneezes, coughs or laughs. Tuberculosis cannot be spread, by contact. Tuberculosis is caused by a rod shaped bacterium or bacillus called Mycobacterium tuberculosis. These droplets are discharged into the air by a person with active tuberculosis (Britannica, 2012). The spreading progress is very effective. These droplets can remain in the air for several hours in addition it only needs ten bacilli to start an infection. When the infected air is breathed in, the bacilli enter the lungs through the bronchioles and into the alveoli. The bacilli then infect the alveoli

According to the World Health Organization (WHO), one-third of the world population is or has been infected with M. tuberculosis8. While this rate appears to be exceptionally high, only a few of the infected end up developing active tuberculosis in their lifetime. Most of the infected people have the inactive form (latent tuberculosis infection LTBI) of tuberculosis that poses no immediate problems.

Most people who are exposed to Tuberculosis never develop symptoms because the bacteria can live in an inactive form in the body, also known as Latent Tuberculosis, or Latent TB. But if the immune system weakens, such as in people with HIV or elderly adults, Tuberculosis bacteria can become active. Active Tuberculosis disease can be fatal if left untreated. In Latent Tuberculosis, the bacteria are in an inactive state and can cause no symptoms, and are not

When one inhales air coughed out by TB patients, the infection is referred to as primary tuberculosis. In most instances, most people get infected with primary tuberculosis, but since its severity is minimal, there are higher chances of recovery (CDC 17). The infection rate of primary tuberculosis depends on the strength of an individual’s immune system.
