Tuberculosis (commonly shortened to TB) is an infection caused by the bacterium Mycobacterium tuberculosis, which most commonly affects the lungs (pulmonary TB) but can also affect the central nervous system (meningitis), lymphatic system, circulatory system (Miliary tuberculosis), genitourinary system, bones and joints.\n\nTuberculosis is one of the most deadly and common major infectious diseases today, infecting two billion people, or approximately one-third ( WHO TB.) of the world's population. Nine million new cases of the disease, resulting in two million deaths, occur annually, mostly in developing countries. However, developed countries are not spared the burden of tuberculosis. There is a rising number of people in the developed world who contract tuberculosis because they have compromised immune systems, typically as a result of immunosupressive drugs or HIV/AIDS. These people are at particular risk of tuberculosis infection and active tuberculosis disease.\n\nMost of those infected (90%) have asymptomatic latent TB infection (LTBI). There is a 10% lifetime chance that LTBI will progress to TB disease which, if left untreated, will kill more than 50% of its victims. TB is one of the top three infectious killing diseases in the world: TB kills 2 million, and malaria kills 1 million.\n\nThe neglect of TB control programs, HIV/AIDS, and immigration has caused a resurgence of tuberculosis. Multiple drug resistant strains of TB (MDR-TB) and Extreme Drug-Resistance in Tuberculosis (XDR-TB) are emerging. The World Health Organization declared TB a global health emergency in 1993, and the Stop TB Partnership proposed a Global Plan to Stop Tuberculosis which aims to save an additional 14 million lives between 2006 and 2015.

HIV (Human immunodeficiency virus) attacks the body's immune system. When it does, HIV weakens the body's ability to fight off infection. If left untreated, HIV will eventually weaken the immune system so much that the person will become sick from certain types of infections. When the person gets these infections, he or she is said to have AIDS (acquired immunodeficiency syndrome). For some, it takes a long time to develop these infections and therefore AIDS. For others it takes less time. Not everyone with HIV has AIDS and AIDS is not the same as HIV.

It is normal flora and is not very virulent at all in normal people, however in aids patinets it is a very common infection and can be their cause of death, through symptoms similar to mycobacterium tuberculosis.  Good question.

Yes, it's an uncommon infection which affects people who have depressed immune systems.  It is in the same family as TB but not as catchy to normal people.  There are lots of ways to treat it.  It is spelled with a "y", mycobacterium.  Good luck.

It makes your heart, lungs, muscles and whole body work better.  It improves your immunity to disease and it stops you getting fat.  It also decreases the chance of you becoming diabetic as you get older.

Initially a feeling of malaise and a mild cough, which may produce green or yellow mucous. As the disease progresses, the quantity of sputum increases; and there may be blood in it. A characteristic symptom is waking at night covered with sweat. Fluid in the pleural space make the sufferer short of breath. Occasionally the infection will spread to other parts of the body, including the kidneys, the bladder, the prostate, or the ovaries. The tuberculosis bacterium can attack the skin, heart, brain, or bones.

SARS, of course, affects mostly the respiratory system (lungs).  However, it also affects the muscular system (muscle aches) and, in some people, the digestive system (diarrhea).

Yes BCG does confers some immunity against T.B, which is a live attenuated that is weak strain of a T.B organism knowna as Mycobacterium bovis , which is injected in ur blood stream, it offers partial resistance to tuber culosis remeber partial resistance , that is prevents appearance of clinical disease in children particularly , but it certainly does'nt prevent infection from T.B. as the organism is different called Myco bacterium Tuberculosis and this one u are injected with is is mycobacterium bovis , so it's related to the other one , and offers partial resistance but not complete immunity .

Malta fever does not do any permanent damage to humans.   It is a bacterial infection usually treated by antibiotics.

No we don't. The human immune system is an extraordinary thing much like the rest of it's systems. The more it's exercised the stronger it gets. Avoiding germs and bacteria only makes people weaker.

Treatment of tuberculosis (TB) takes six to nine months and sometimes longer. Like all medications, your tuberculosis tablets can cause side effects and you should speak to your doctor if these occur. Your doctor will monitor your progress during treatment to make sure the medication is working. This will usually involve blood, sputum or urine tests and chest x-rays.

Yes,, if a person has active tuberculosis\n and licks a spoon ......\n the person who puts, that spoon in there mouth\n ( without thoroughly cleaning it first ,may  contact  tuberculosis .\n\n It is mainly spread ,through coughing in public ;\n\n ( airborne bacillus are inhaled, &  can infect any one)\nWho is not   protected,\n by a mask or  succesfully  vaccinated against   tuberculosis.\n( BCG vaccine )\n\n>^,^<

there are plenty of antibiotics now that may increase life, HIV hurts the body's immune system because the bodies T-cells are infected, usually people don't die from HIV/AIDS but from common diseases such as the flu, diarrhea, common cold.

Most probably it will get infected. And if then you don't treat the infection on time you might lose that part of the body and even die. But it will take a few days or even weeks before it happens

this is very true...we have terrible problems with TB in Miami, Dade County...not many ppl know about it...its from many nations in the Caribbeans ...I really don't want to name the countries, but I know of one that is absolutely famous for it!

Consumption, the great killer \n  \nNATIONAL LIBRARY OF MEDICINE \nWorldwide tuberculosis deaths total 1 billion in two centuries. \nTuberculosis is an ancient enemy. Human bones from the Near East dating back five millennia show the telltale pitting of TB. Mummies from Egypt ca. 2400 BCE show tubercular decay in their spines.\n\nThe ancient Greeks described it, too. Around 460 BCE, Hippocrates identified phthisis, or consumption, as the most widespread disease of his age. It was almost always fatal. Because of that, he advised his followers and students against treating late-stage consumption to avoid damage to their reputations.\n\nIt was called the “king’s evil” in medieval Europe because newly crowned kings (and queens, in England) were alleged to cure scrofula, glandular swellings in the neck associated with TB, with their touch.\n\nMoving toward the present, Franciscus dele Bo Sylvius described the progress of the disease in his Opera Medica of 1679. Two decades later, a public-health edict from the Republic of Lucca in Italy recognized the infectious nature of the disease: “Henceforth, human health should no longer be endangered by objects remaining after the death of a consumptive. The names of the deceased should be reported to the authorities, and measures taken for disinfection.”\n\nBenjamin Martin, an English physician and author of A New Theory of Consumption (1720), hypothesized that TB resulted from the actions of “wonderfully minute living creatures.” Once those creatures established themselves in the body, Martin thought, they would generate the characteristic symptoms of consumption. He further theorized that close contact with a consumptive, including frequent conversation so close as to “draw in part of the breath he emits from the Lungs,” was enough to transmit the disease.\n\nIn 1865, a French military doctor, Jean-Antoine Villemin, demonstrated that the disease could be passed from humans to cattle, and from cattle to rabbits. This was a remarkable breakthrough, because despite Martin’s wondrously small organisms, medical theory still held that each case of consumption arose spontaneously in predisposed people.\n\nA few years later, in 1882, Robert Koch demonstrated conclusively that a bacterial infection caused TB. Later investigations proved that air and secretions expelled from consumptive lungs contained live bacteria.\n\nWhether it is known as lupus vulgaris (TB of the skin), Pott’s disease (TB of the bones), or consumption (the “classic” case of lung disease), TB is one of history’s great killers. It is estimated to be responsible for 20% of the deaths in 17th-century London and 30% of those in 19th-century Paris (as recently depicted in the popular film Moulin Rouge). Although not as aggressive as plague, TB has killed more people in history than the black death, leprosy, or HIV. An estimated 1 billion people around the world have been felled by TB in the past two centuries, and the fatalities continue.\n\n“Romantic” and deadly\nAlthough TB is considered a single disease, it has been caused by at least two microorganisms. Long before TB began killing humans, it afflicted cattle. After cattle became one of humanity’s client species sometime between 8000 and 4000 BCE, however, there is evidence that Mycobacterium bovis infected humanity through the ingestion of milk. This coincides with the earliest discoveries of telltale lesions in human spines dating from 5000 BCE.\n\nHowever, after 1000 BCE the strain of TB seems to have changed. After that time, pulmonary TB caused by M. tuberculosis became widespread. M. tuberculosis is most likely an evolved form of M. bovis that developed among milk-drinking Indo-Europeans, who then spread pulmonary TB on their migrations. By the first millennium BCE, pulmonary TB was endemic throughout the world. The earliest recorded symptoms of pulmonary TB—cough, expectoration, hemoptysis, and wasting—are found in the library of Assu
