How did TB spread?
In South America, reports of a study in August 2014 revealed that TB had likely been spread via seals that contracted it on beaches of Africa, from humans via domesticated animals, and carried it across the Atlantic. A team at the University of Tübingen analyzed tuberculosis DNA in 1,000-year-old skeletons of the Chiribaya culture in southern Peru; so much genetic material was recovered that they could reconstruct the genome. They learned that this TB strain was related most closely to a form found only in seals. In South America, it was likely contracted first by hunters who handled contaminated meat. This TB is a different strain from that prevalent today in the Americas, which is more closely related to a later Eurasian strain.

Is fluoroquinolone effective against tb?
Fluoroquinolones are a crucial component of regimens for multidrug-resistant tuberculosis, but have not yet assumed a regular role in treating drug-susceptible disease. Although moxifloxacin is more effective than ethambutol in achieving sputum conversion at 8 weeks ( 54 ), clinical trials have not shown that the use of fluoroquinolones enables current regimens to be shortened to 4 months. A 4-month trial of both moxifloxacin and gatifloxacin plus rifampin, isoniazid, and pyrazinamide given three times weekly versus the 6-month standard of rifampin, isoniazid, pyrazinamide, and ethambutol had to be stopped early because of high relapse in the quinolone group ( 55 ). Levofloxacin and moxifloxacin appear to be equal in their effectiveness against tuberculosis ( 56 ). Moxifloxacin did not improve outcomes when added to rifampin, isoniazid, pyrazinamide, and ethambutol. When substituted for pyrazinamide or rifampin, the results were worse. When it was used instead of isoniazid, there was an earlier sputum conversion ( 57 ).

Overview
- Tuberculosis (TB) is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs. Tuberculosis is curable and preventable.
- Tuberculosis (TB) is a potentially serious infectious disease that mainly affects your lungs. The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes.Once rare in developed countries, tuberculosis infections began increasing in 1985, partly because of the emergence of HIV, the virus that caus…
Treatment
- TB is a treatable and curable disease. Active, drug-susceptible TB disease is treated with a standard 6 month course of 4 antimicrobial drugs that are provided with information, supervision and support to the patient by a health worker or trained volunteer. Without such support, treatment adherence can be difficult and the disease can spread. The vast majority of TB cases …
- While this disease can be fatal if left untreated, the good news is that treatment is available for both latent and active TB. A health care provider may prescribe antibiotics for individuals with latent TB to clear out any existing inactive bacteria and prevent them from causing disease. For those with active TB, several different antibiotics will likely be provided to treat the infection. Its …
- While bone tuberculosis can lead to some painful side effects, the damage is usually reversible when treated early with the right regimen of medications. In many cases, spinal surgery is necessary, such as a laminectomy (where a part of the vertebrae is removed). Medications are the first line of defense for bone tuberculosis, and the course of treatment can last anywhere from 6…
- Medications are the cornerstone of tuberculosis treatment. But treating TB takes much longer than treating other types of bacterial infections.For active tuberculosis, you must take antibiotics for at least six to nine months. The exact drugs and length of treatment depend on your age, overall health, possible drug resistance and the infection's location in the body.
Signs And Symptoms
- Common symptoms of active lung TB are cough with sputum and blood at times, chest pains, weakness, weight loss, fever and night sweats. Many countries still rely on a long-used method called sputum smear microscopy to diagnose TB. Trained laboratory technicians look at sputum samples under a microscope to see if TB bacteria are present. Microscopy detects only half the …
- Although your body may harbor the bacteria that cause tuberculosis (TB), your immune system usually can prevent you from becoming sick. For this reason, doctors make a distinction between: 1. Latent TB. In this condition, you have a TB infection, but the bacteria remain in your body in an inactive state and cause no symptoms. Latent TB, also called inactive TB or TB infection, isn't co…
- Tuberculosis disease: If the body's immune system is unable to keep the bacteria in check, the infection can result in active tuberculosis. People with active TB usually have one or more symptoms of the disease and may be very contagious to others. While TB typically affects the lungs, the brain, kidneys, spine, and other organs can also be affected. General symptoms include:
- Its not always easy to recognize the symptoms of bone tuberculosis until its far advanced. Bone TB spinal TB in particular is hard to diagnose because its painless in the early stages, and the patient may not be exhibiting any symptoms. When bone TB is finally diagnosed, signs and symptoms are usually very advanced. In addition, sometimes the disease can be dormant in the …
Diagnosis
- The use of the rapid test Xpert MTB/RIF® has expanded substantially since 2010, when WHO first recommended its use. The test simultaneously detects TB and resistance to rifampicin, the most important TB medicine. Diagnosis can be made within 2 hours and the test is now recommended by WHO as the initial diagnostic test in all persons with signs and symptoms of TB. Diagnosing …
- The imaging differential is dependent on the type and pattern of infection; consider: 1. differential of miliary pulmonary opacities 2. differential of alveolar pulmonary consolidation 3. differential of a pulmonary cavity...
- First, it might be helpful to clarify that there are two different types of TB tests: the tuberculin skin reactivity test (also called the Mantoux Test) and the TB blood test. The skin test will help to determine whether a person has ever been exposed to the TB protein by injecting a small bubble of fluid with purified TB protein (which doesnt cause illness) into the skin of the forearm. A healt…
- During the physical exam, your doctor will check your lymph nodes for swelling and use a stethoscope to listen carefully to the sounds your lungs make while you breathe.The most commonly used diagnostic tool for tuberculosis is a simple skin test, though blood tests are becoming more commonplace. A small amount of a substance called PPD tuberculin is injecte…
Causes
- Tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air. This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings.Although tuberculosis is contagious, it's not easy to catch. You're much more likely to get tuberculosis from someone you live with or …
- So how does someone get exposed to this bacterium in the first place? Tuberculosis can be spread through droplets in the air when someone with an active infection coughs or sneezes. Certain factors can increase the chance of being exposed to TB bacteria, including:
- Bone TB occurs when you contract tuberculosis and it spreads outside of the lungs. Tuberculosis is normally spread from person to person through the air. After you contract tuberculosis, it can travel through the blood from the lungs or lymph nodes into the bones, spine, or joints. Bone TB typically begins due to the rich vascular supply in the middle of the long bones and the vertebrae.
- Persons who are at a greater risk for developing active TB include those infected with HIV, patients who have been infected with TB bacteria in the past 2 years, users of illicit IV drugs, and those who currently have other diseases that weaken the immune system. Other patients at risk may include infants, the elderly, and people who were not treated appropriately for TB in the past…
Prevention
- If you test positive for latent TB infection, your doctor may advise you to take medications to reduce your risk of developing active tuberculosis. The only type of tuberculosis that is contagious is the active variety, when it affects the lungs. So if you can prevent your latent tuberculosis from becoming active, you won't transmit tuberculosis to anyone else.
- The Bacilli Calmette-Guerin (BCG) Vaccine: The BCG vaccine works against two specific forms of TB: childhood tuberculosis meningitis (TB in the central nervous system) and military disease (TB that causes lesions throughout the body). Many people who have lived in countries with a very high risk of TB exposure have been vaccinated these individuals will likely get a positive skin rea…
- Bone tuberculosis is more of a risk in developing nations or for people living with AIDS. However, while the risk of tuberculosis is low in developed nations, bone tuberculosis is still something to watch out for. When this disease is diagnosed, it can be treated with a regimen of medications, and in more severe cases medications can be used in addition to surgical intervention.
- Many of those who are infected with TB do not develop overt disease. They have no symptoms and their chest x-ray may be normal. The only manifestation of this encounter may be reaction to the tuberculin skin test (TST) or interferon-gamma release assay (IGRA). However, there is an ongoing risk that the latent infection may escalate to active disease. The risk is increased by oth…
Epidemiology
- About one-quarter of the world's population has latent TB, which means people have been infected by TB bacteria but are not (yet) ill with the disease and cannot transmit the disease. Tuberculosis mostly affects adults in their most productive years. However, all age groups are at risk. Over 95% of cases and deaths are in developing countries. People who are infected with HI…
- In the United States, only about 3 percent of all TB cases affect the musculoskeletal system. Of those cases, the spine is most commonly affected. Therefore, if you have bone TB, you are more likely to have it in or on your spinal column. However, bone TB could potentially affect any bone in your body. A common form of spinal bone TB is known as Potts disease. Bone tuberculosis is re…
- 1. TB is the second most common cause of death from infectious diseases after HIV/AIDS. 2. An estimated 10 million people developed TB in 2017. However only 64% of cases were notified and reported to the World Health Organization (WHO). 90% were adults (aged 15 years or more), and 9% were people with HIV. 3. About 1.7 billion people (23% of the world's population) are estimat…
Risks
- Anyone can get tuberculosis, but certain factors can increase your risk of the disease. These factors include:
- Tuberculosis is directly caused by bacteria which spreads from one person to another through microscopic droplets that are released into the air.According to the CDC, the droplets are from someone who is untreated and has an active form of tuberculosis when he/she speaks, coughs, spits, sneezes, laughs or sings.Tuberculosis is contagious, but it is difficult to catch. A person is …
- If youve had the Bacille Calmette-Guérin (BCG) vaccine, you can get TB. Therefore, you still should receive skin tests. This vaccine is not generally recommended for health care workers. It can cause a mild positive reaction to the skin test. Usually, the reaction becomes less severe over time. If your result worsens, you may have TB and will need treatment.
- At high risk for developing active TB include: 1. People with HIV infection. 1. Because HIV weakens the immune system, people with both TB and HIV infection are at high risk of developing TB disease. 2. If you are HIV-positive, you are 30 times more likely to get active TB once infected than someone infected with TB who is HIV-negative. 3. People with HIV should be TB tested an…
Prognosis
- People infected with TB bacteria have a 515% lifetime risk of falling ill with TB. However, persons with compromised immune systems, such as people living with HIV, malnutrition or diabetes, or people who use tobacco, have a much higher risk of falling ill. When a person develops active TB disease, the symptoms (such as cough, fever, night sweats, or weight loss) may be mild for man…
- Treatment is usually only in the setting of progressive primary tuberculosis, miliary tuberculosis or post-primary infection, and in general primary infections are asymptomatic. For a general discussion please refer to the parent article: tuberculosis.Administration of protracted courses of multiple antibiotics tailored to the sensitivity of the infective strain is the cornerstone of treatme…
- Latent tuberculosis: In most cases, when generally healthy people are exposed to the TB bacteria, the bodys immune system does a good job of preventing the bacteria from causing illness. In cases where the body does not effectively get rid of the TB infection entirely, the TB bacteria may remain in the body in a dormant, inactive state. People with this latent form of TB don't have sym…
- Infection is manifested by a positive TST or IGRA result 810 weeks after exposure. Overall, only 5%10% of otherwise healthy people have an infection that progresses to disease during their lifetime. Progression to disease can occur weeks to decades after initial infection. People with TB disease have symptoms or other manifestations of illness such as an abnormal chest radio-gra…
Complications
- Without treatment, tuberculosis can be fatal. Untreated active disease typically affects your lungs, but it can spread to other parts of your body through your bloodstream. Examples of tuberculosis complications include: 1. Spinal pain. Back pain and stiffness are common complications of tuberculosis. 2. Joint damage. Tuberculous arthritis usually affects the hips and knees. 3. Swelli…
- There are no symptoms associated with inactive TB. This means that someone may have acquired the TB bacteria and yet show no signs or symptoms of infection. Symptoms only appear when the TB infection becomes active. Symptoms develop gradually, and it may take many weeks before you notice that something's wrong and see your doctor. Although the TB bacteria can inf…
