Why are antibiotics resistant to TB?
Some people have TB bacteria which are 'resistant' to certain antibiotics - meaning that the bacteria are not killed by that antibiotic. This means that other antibiotics have to be used instead, to cure the TB. So antibiotic resistance can make the TB more difficult to treat and more dangerous to others who are infected. Difficulty of treatment is increased if the bacteria are resistant to more than one antibiotic. This is called multidrug-resistant (MDR) TB. If the bacteria are resistant to more than three antibiotics, this is called extensively drug-resistant TB.
What is TB infection?
Tuberculosis (TB) is an infection with a germ (bacterium) called Mycobacterium tuberculosis. If you have symptoms, or a doctor can find signs of the infection when examining you, this is known as active TB. If you have TB infection without any signs or symptoms, this is known as latent TB.
What is the cause of TB?

Overview
- 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…
- Tuberculosis (TB) is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs. Tuberculosis is curable and preventable.
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
- 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…
- 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 …
- 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 …

- 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.

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…

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.

- 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…
