Tuberculosis, Or More Commonly Tb

Tuberculosis (TB) is caused by a bacteria called Mycobacterium Tuberculosis, which normally affects the lungs, but it can also affect any part of the body, including the bones and the nervous system. The disease is spread easily through prolonged exposure to someone who has the illness, from their coughs and sneezes. For a healthy individual the body’s immune system kills the bacteria and prevents it from spreading in the body, which is known as ‘latent TB’. However, if the immune system fails to fight the bacteria, it can easily spread in the body. Symptoms will develop within a few weeks or months depending on the individual. This is known as an ‘active TB’. The symptoms are, constant coughing that brings up phlegm that may also contain blood, which lasts more than three weeks, combined with weight loss, tiredness and fatigue, loss of appetite and also fever. Without treatment, TB can cause major health problems and if its left untreated can even cause death (NHS 2016).

There are two different types of tests that are used to determine if there is TB in the body. The first test is the TB skin test (TST) and the second one is TB blood test. A positive TB skin test or TB blood test only discloses if a person has been infected with TB bacteria. It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease. Further testing, such as a chest x-ray and a sample of sputum (mucus), is necessary to see whether the person has TB disease. (https://www.cdc.gov/tb/topic/basics/tbinfectiondisease.htm)

Active TB is when the disease is actively producing symptoms such as a cough for three weeks or longer,weight loss,loss of appetite,high temperature or fever,night sweats,extreme tiredness or lack of energy can be transmitted to other people; latent disease is when the person is infected with Mycobacterium tuberculosis bacteria, but the bacteria are not producing symptoms (usually due to the body's immune system suppressing the bacterial growth and spread) and have no TB bacteria in the sputum. People with latent TB usually

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 (TB) is a disease caused by infection with the Mycobacterium tuberculosis bacteria. The CDC estimates that one third of the global population was infected with TB in 2015 (as cited in Hebert, 2016). That figures varies greatly by country, with the 2011-2012 National Health and Nutrition Examination Survey (NHANES) estimating a prevalence of 4.7% for US residents. (Castro et al., 2015) There was further variation within the US population in regards to age, sex, race/ethnicity, and whether or not the individual had been born in the US. The study excluded those under 6 years of age, serving in the armed forces, or

Tuberculosis is a bacterial infection disease characterized by the growth of nodules in the tissues, especially the lungs. Tuberculosis is also known as TB. TB can affect anyone if they are exposed to the air droplets of an affected person. TB can affect areas of the body other than the lungs. TB is high contagious and should be take seriously. If gone untreated it can be fatal.

Tuberculosis, also known as TB, is a very common bacterial infection. It can travel through your bloodstream and infect any organ in your body. It can be in an inactive form, which means these people will never develop symptoms. Those with weaker immune systems are more likely to have an active TB infection. Tuberculosis is caused by Mycobacterium tuberculosis, which is also the scientific name of tuberculosis. Mycobacterium tuberculosis is a long, slender, straight (sometimes slightly curved) rod. It is neither gram-positive, nor gram-negative because it has a high lipid content within its wall. Because of this, acid-fast staining is used. Mycobacteria tuberculosis reproduce by binary fission which is a form of asexual reproduction. They reproduce quickest and best in an oxygenated area ("Tuberculosis", 2016). Below, you will find all you need to know about tuberculosis, including epidemiology, incubation and duration, signs and symptoms, diagnosis, treatment, and even a case study on TB itself.

TB is an infectious disease. This means that disease causing pathogens, such as bacteria, viruses, fungi and protoctists, attack and contaminates the host’s cells, then spreads to other cells within the body.

The symptoms of tuberculosis can manifest differently depending on the location of the infection. The majority of infections are located in the lungs and include

There are different types of TB that a person can develop a couple examples are latent and active. Latent TB is where there are no physical symptoms of the disease, making it hard to diagnose unless the correct tests are carried out for example chest x-rays. This type is not contagious and if not treated can eventually become active and contagious. Active type of TB is where the bacteria infects different organs, mainly the lungs causing this type to be contagious.

Tuberculosis does show any different physical signs than regular tuberculosis. Both forms of tuberculosis show coughing for more than 3 weeks, coughing up blood or mucus, chest pain, fatigue/weakness, weight loss and loss of appetite, fever, and chills (1). Tuberculosis is easily caught by a new patient because the air that is contaminated by a carrier of the bacteria who has been in the room for a rather long time. Meaning if a person visits the carrier and goes into the carrier’s bedroom for an extended length of time, then that person could possibly contract tuberculosis. Not only is immediate contact a key factor in developing tuberculosis, health, where a person lives, and if that person developed tuberculosis in the past. These factors all accumulate and help in the spread of the disease from person to person.

Tuberculosis is a bacterial infection that is spread through the air. As there is with any other disease, Tuberculosis, or TB, has its telltale signs and symptoms. One symptom with TB is a cough that lasts more than three weeks. TB also causes the person to cough up blood. Chest pain, or pain while breathing or coughing is another symptom of TB. If you have unintentional weight loss, you should see a doctor because you may have TB or a gastrointestinal disease. The usual fatigue and loss of appetite are also associated with TB. Night sweats and chills are also TB-related. You should call a doctor if you have the more intense symptoms or two or three of the moderate symptoms. For example if you have night sweats that leave you soaked in the morning, persistent cough and unexplained weight loss, you should call a doctor because you may have TB; even if you do not have it you should still see a doctor because you probably are sick in one way or another.

There are many ways to identify and diagnose the presence and severity of tuberculosis. One of the most prevalent ways to test for TB is

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.
