M. bovis, a specific species of bacterium, causes bovine tuberculosis. Bovine tuberculosis mostly affects cattle, although it may infect virtually any mammal, causing general disease, coughing, and death. It may be passed from animals to people as well as from humans to other animals. Transmission between people is usually through the air when someone with infected lungs breathes out aerosolized bacteria.
Bovine tuberculosis has been found in human lungs only after autopsy. Such cases are rare but have been reported. Person-to-person transmission has never been documented.
The best protection against bovine tuberculosis is vaccination. There are two types of vaccine available: live and killed. The live vaccine protects cows by stimulating their immune systems to produce antibodies that fight off infection. It must be given together with an antibiotic so that it will be taken up by cells where it can cause no harm but instead stimulates a strong immune response. This approach does not work for humans. The killed vaccine contains parts of the M. bovis bacterium already weakened so that they do not cause problems for vaccinated animals but can still cause disease in unvaccinated ones. It should not be used in pregnant cows or cows about to give birth because it could cause premature delivery or affect the calf's health.
The TB complex is predominantly a disease that infects cattle. Humans, on the other hand, can become sick, most often through consuming unpasteurized milk products from diseased cows. Raw milk sold in states where it is illegal to sell without federal regulation contains bacteria that can cause illness in humans. Even if you purchase milk that has been heated to destroy any harmful bacteria, some people are still at risk of getting sick because they develop allergies or other issues with their immune system. Drinking raw milk can also lead to legal problems for farmers because the law considers cows to be property, not livestock. In order for farmers to protect their investments, it is best not to put them at risk of injury or death by selling them raw milk.
People who drink raw milk regularly should discuss its safety with their doctor. Those who have existing health problems or take medications may not be able to drink raw milk without risking being harmed by it. Anyone who suspects they may be allergic to milk should avoid it until testing confirms this fact.
Drinking raw milk is not recommended as an effective way of preventing or treating tuberculosis.
Mycobacterium tuberculosis (MTB) is an infectious illness caused by the bacteria Mycobacterium tuberculosis (MTB). Tuberculosis is most commonly associated with the lungs, although it may also affect other regions of the body. Most infections do not cause symptoms, in which case it is referred to as latent TB...

Tuberculosis (TB) is a disease caused by bacteria that spread via the air from person to person. TB most commonly affects the lungs, but it can also affect other regions of the body such as the brain, kidneys, or spine. If a person with tuberculosis does not receive treatment, they may die. However, this is more likely if they have another serious illness along with TB or if they are immune compromised due to medications for another condition or HIV/AIDS.
People who are infected with TB but do not show symptoms may be spreading the disease. This is called latent TB infection or LTBI. The only way to know if someone has LTBI is through testing. Some countries require people to take medication after exposure to TB in order to prevent them from developing active TB. These treatments are different for each person and usually include isoniazid for six months or longer depending on how exposed they were to determine whether they need to be treated further.
TB is treatable. With proper treatment any patient with TB can be cured. Patients cannot be cured if they don't take their medications correctly or if they develop drug-resistant TB. Resistant TB is when the antibiotics used to treat the infection no longer work. This can happen if a patient fails to complete their course of therapy or if they are prescribed an incorrect dose of drugs.
Resistance is also seen if a patient receives multiple prescriptions for various types of antibiotics.
Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis. Typically, the bacteria attacks the lungs. However, it can also infect other parts of the body including the brain, spine, abdomen, kidneys, heart, and skin. Symptoms include fever, cough, weight loss, and weakness. In some cases, people with TB infections may not have any symptoms at all.
A person is infected with TB when they are exposed to the bacteria through inhalation or ingestion. The bacteria then grow inside macrophages, cells that fight off infection and cause them to produce substances that damage surrounding tissue. This in turn leads to inflammation of the lung tissue which can be seen on imaging studies as thickened areas of the lung called tubercles. If left untreated, this disease can spread throughout the body causing various organs to fail.
Currently, there are two main treatments for TB: first-line drugs and second-line drugs. Drugs used to treat TB are called anti-tubercular drugs (ATDs). First-line ATDs include isoniazid, rifampin, pyrazinamide, and ethambutol. These drugs work best if taken together every day.
However, tuberculosis germs may infect any region of the body, including the kidney, spine, and brain. If not treated appropriately, tuberculosis (TB) can be lethal.
The main way that TB affects the body is through its reaction with our immune system. The most common symptom of exposure to M. tuberculosis is a fever and a general feeling of illness. This is followed by a period when many people do not show any symptoms at all.
If infected with TB bacteria, some people will develop active disease while others will maintain their resistance to the infection. Those who develop active disease display various symptoms depending on which part of the body is affected. For example, someone might have trouble breathing with chest pain, weight loss, or night sweats. A physician will be able to diagnose tuberculosis (TB) based on these symptoms and how long they have been present.
There are different types of treatments for tuberculosis (TB). Drugs are often used to kill the bacteria when it is found in areas of the body not vital to survival such as the bones or nervous system. Drugs are also used to prevent the spread of the infection if patients are not yet sick. Some examples of drugs used to treat tuberculosis include isoniazid, rifampin, pyrazinamide, and ethambutol.
Tuberculosis (TB) is caused by a bacterium known as Mycobacterium tuberculosis. It spreads when someone with active tuberculosis in their lungs coughs or sneezes and someone else inhales the ejected droplets, which contain tuberculosis germs.
People are not born with immunity to TB because they have never been exposed to it. If you have been vaccinated against TB but still get infected, you might be able to fight off the disease without getting sick. The best way to avoid getting TB is to not go around spreading the infection anyway possible. This includes not sharing needles used for drug addiction or blood transfusions with people who have not been treated for the infection.
If you do get infected, there are drugs that can kill the bacteria and keep you healthy. The problem is that these drugs take months to become effective and many patients stop taking them, leaving them vulnerable to relapse if they ever were to become infected again.
The best defense against TB is early detection and proper treatment. If someone suspects they may be infected, they should contact their doctor right away so an appointment can be made to receive testing. If detected early, TB is very treatable. There are several different types of medications that can kill the bacteria and help clear up the infection.
