Introduction
Definition:
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 is disseminated between persons through inhaling infectious droplet nuclei aerolized by the

Then large amounts of caseous, a cheese-like material is continually generated. This material then liquefies, makes its way up the respiratory tract and mixes with saliva and becomes sputum, which in turn is coughed up profusely.
Following this process, the damage caused to the lining of the lungs results in the person to experience chest pain. The patient sweats at night, which leads to fever. It can become so severe that bed sheets need to be changed. Other symptoms may be troublesome as well. "I had back pain and numbness in my arm," says Sonia, a nurse with the disease. "My doctor seemed to think those were kind of unusual symptoms for TB."
Children suffering from tuberculosis may not appear to show any symptoms, hence physicicans may not notice during the regular checkups. Many children are diagnosed only when health-department workers are examining the contacts of an adult with the disease. "My kids don 't act sick," Randall points out. "But the doc says that don 't mean nothin '. They might be infected and then get sick real quick. TB can be pretty bad for little kids."
If not treated, the tuberculosis causes the lungs to be so damaged that simply breathing becomes a challenge. What follows is a continuous illness that consumes the body and due to haemorrhage (bleeding in the lungs) the patient dies. The death rate for untreated patients with
Tuberculosis is caused by the bacteria “Mycobacterium Tuberculosis” and is mainly causes infection of the lungs (WHO, 2016). Its mode of transmission is airborne, so it can be passed on by inhalation of airborne droplets which carrying the bacteria, when an infected patient coughs, sneezes, or spits the TB germs into the air (WHO, 1026). Among the symptoms of active TB are: cough with sputum and blood, chest pains, weakness, fever and night sweats (WHO, 2016). Most at risk to get the TB infection are people with weakened immune system such as people who are suffering from chronic diseases such as diabetes mellitus, severe kidney disease, silicosis and especially HIV infection (CDC, 2016). Children and Tobacco users are also at greater risk to fall ill with TB.
Tuberculosis is a disease of an infectious nature caused by a bacterium known as mycobacterium tuberculosis. The disease spreads through the air. People with the disease can spread it to susceptible people through coughing, sneezing, talking or spitting. It mainly affects the lungs and other parts such as the lymph nodes and kidneys can also be affected. The symptoms for TB are fatigue, coughing, night sweats, weight loss and fever. One third of the population of the world is affected with mycobacterium tuberculosis. The rate of infection is estimated to be one person per second. About 14 million people in the world are infected with active tuberculosis. Drug resistant TB has been recorded to be a serious public health hazard in many countries. Resistant strains have developed making it difficult to treat the disease. TB has caused millions of death mainly in people living with HIV/AIDS ADDIN EN.CITE Ginsberg19981447(Ginsberg, 1998)1447144717Ginsberg, Ann M.The Tuberculosis Epidemic: Scientific Challenges and OpportunitiesPublic Health Reports (1974-)Public Health Reports (1974-)128-13611321998Association of Schools of Public Health00333549http://www.jstor.org/stable/4598234( HYPERLINK l "_ENREF_3" o "Ginsberg, 1998 #1447" Ginsberg, 1998). The World Health Organization came up with the DOTS (Directly Observed, Therapy, Short course) strategy. The approach involves diagnosing cases and treating patients with drugs for about 6-8
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).
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 an infectious disease that affects a persons lungs and has the ability to be life threatening. The bacteria that causes TB is known as Mycobacterium tuberculosis (MTB) (https://www.cdc.gov/tb/topic/basics/). The TB bacteria is spread from person to person when an infected person coughs or sneezes and minute droplets enter the air. Approximately one third of people throughout the world have latent TB
Tuberculosis (TB) is caused by the Bacterium Mycobacterium tuberculosis also called tubercle bacilli which is an aerobic non-motile bacillus which are approximately 2-4 micrometers in length and 0.2-0.5 um in width.
Pulmonary tuberculosis is usually caused when a person coughs or sneeze and breath in air droplets of a bacteria called Mycobacterium tuberculosis (M. tuberculosis). Sometimes; if a person lives in a small contained home that is not cleaned and have no sunlight coming into the home may put them at risk of developing tuberculosis. Homeless people can be at risk for tuberculosis because that are not getting any nutrition and live in a poor environment. People that are living with HIV are really at risk of contracted TB because their immune system may be low and are unable to fight off the bacteria due to medication they may be taking. People do not have to necessarily be around a person with TB, their poor living situation can cause them to contracted TB. This bacteria mycobacterium
Tuberculosis (TB) is a bacterial (Mycobacterium tuberculosis) disease that typically targets the lungs, but can also infect other areas in the body, such as the spleen, heart, and brain (this is very rare, however). The transmission of TB can be passed on by a sneeze, cough or spit. Thus, propelling the bacteria to spread into the air, making nearby bystanders that inhale the bacteria infected, but the real danger is to those who are constantly around the infected person, those included could be family members, friends, and health care workers. Keep in mind, however, that TB is not spread by handshaking, sharing food or drinks, using the same toilet seat, and kissing. Some of the symptoms associated with TB include a cough that last more than three weeks, chest pain, coughing up blood or mucous, weakness or fatigue, loss of weight, loss of appetite, chills, fever, and night sweats.
Tuberculosis or TB is caused by Mycobacterium tuberculosis. Mycobacteria are aerobic bacteria, which do not form spores and are non-motile. They are curved, intracellular rods, and have cell walls made of glycolipids and phospholipidglycans that protect them from lysosomal attacks. TB is one of the world’s deadliest diseases. Approximately one out of three people worldwide are infected; in 2014, 9.6 million people were diagnosed with TB and there were 1.5 million deaths (CDC, 2014). This disease is highly contagious, and although the number of cases reported has decreased, the decrease was smaller than in previous years. New strains of drug resistant TB pose a threat to the global population as a whole; less than half of those diagnosed with drug-resistant TB are successfully cured.
Tuberculosis disease is what causes the infected to become sick with the signs and symptoms of TB. A risk for most people who become infected with tuberculosis is being infected with the drug-resistant type. The some tuberculosis bacteria has become immune to the antibiotics used to treat people with the disease. There is an increase of fatality due to this disease if a person has contracted the drug resistant bacteria.
Tuberculosis (TB) is one of the world’s most fatal diseases. One third of the world’s population is infected with TB. Tuberculosis is the primary killer among people infected with HIV. TB has been reported in the United States since 1953. Although, mortality information suggests we have learned to manage the disease overtime, people with TB can die if they do not acquire proper treatment. According to the Centers for Disease Control and Prevention over nine thousand cases have been reported with TB incidences in the United Sates in 2012; over eighty-four thousand was reported in 1953. TB is caused by the bacterium Mycobacterium tuberculosis. The disease mainly affects the lungs, but it may also infect other body tissues and organs.
Over the past century, tuberculosis has taken the lives of more than one hundred million people. Today, roughly two billion people are infected with the bacteria that causes Tuberculosis and five to ten percent develop active tuberculosis within their lifetime. All in all, Tuberculosis resides to be one of the most fatal diseases in the world and is the top ranked killer amongst bacterial diseases. Almost two million people pass away from the infection each year (Furlow, 2010). Approximately thirteen percent of people that are infected with tuberculosis also have HIV, they are closely associated with one another (Tomford, 2010).
Finding it early and finding it late can be a great deal when looking at the various symptoms of tuberculosis. Depending on what type of TB you are; secondary or active tuberculosis multiple symptoms can vary depending on how it spreads through your body. Typically, people with tuberculosis can’t honestly notice if they have TB which leads to major costly operations or death. If they do, it usually starts with a blood-tinged cough or pain in the chest. The blood-tinged cough can also be chronic (constant) and the pain in the chest can be felt simply through just breathing. Throughout the whole body, the most common symptoms can be, chills, fatigue, fever, sweating or sweating of muscles, loss of appetite etc. These common symptoms most likely are depicted as natural occurrences of the body, which is why it is truly not known when you have TB. Although if it occurs too often you can notice it instantly as long as you pay attention to the way your body feels. Along with the outside of the body, the inside of the body can be affected; specifically organs. The most commonly affected organs are the lymph nodes. The lymph nodes are most commonly
Tubercle bacillus, more commonly known as Tuberculosis (TB) is an infectious disease that is contagious and airborne. TB is in many cases fatal, infectious disease caused by the strains of mycobacteria. Tuberculosis will typically infect the lungs, but is capable of spreading to other parts of the body. An infected individual can spread the infection by coughing, sneezing, laughing or otherwise transmit of respiratory fluids through the air. Tuberculosis ranks as the second leading cause of death from a single infectious agent, after the human immunodeficiency virus (HIV). In 1012, 8.6 million people fell ill with TB, including 1.1 million cases from individuals living with HIV. Within the same year, 1.3 million people died
Active TB can cause death if not treated when someone has inhaled the TB bacteria and it becomes active it is essential for the person to get proper treatment. It can also become active if the immune system is affected such as cancer, HIV/AIDS, another type of illness, when this happens the tubercles weaken and the TB bacteria can escape. If this does not happen or treatment is stopped Tb can cause blocked airways causing breathing problems, holes in the lungs, and abbesses in the lungs caused by pockets that are formed that bleed out, destroying the lung tissue.
