USA: 20 April 2007 (Northwestern University)
Can gastrointestinal TB trigger severe joint inflammation?
intestinal infections can trigger arthritic episodes.
TB is an airborne disease it tends to spread mostly through air, if the infected person simply coughs,sneezes,talks or even breathes the infection will be likely to be spread if a person inhales it then they'll be likely to have tb
The evolution of Mycobacterium tuberculosis bacteria in response to their new environment involves the selection of genetic mutations that confer survival advantages, such as antibiotic resistance or enhanced virulence. Over time, these advantageous traits become more common in the bacterial population, leading to the adaptation of Mycobacterium tuberculosis to its new environment.
Is M. tuberculosis acid fast or non-acid fast?
Mycobacterium tuberculosis is an acid fast bacterium. It has a high concentration of mycolic acids in the plasma membrane which prevent its staining by typical Gram stain methods. It must be stained with a procedure containing an acid decolorizing step to best visualize it under the microscope (Ziehl Nielson or Kinyon Methods). It resists decolorization with the acid, which is where the term "Acid Fast" comes from....
What type of organism causes tuberculosis?
Tuberculosis is caused by the bacterium called as Mycobacterium tuberculosis.
"Consumption" is an old name for tuberculosis (TB) that describes how the illness wastes away or consumes its victims. TB is "an ancient enemy" that has plagued humankind for more than five thousand years. The act or process of consuming. Consumption can be either a wasting disease, or the act of using up resources.
Bacteria that cause TB are usually transmitted by coughs, sneezes, or small particles of moisture sprayed from an infected person's mouth while speaking. These small particles may contain very few bacteria, but if they are inhaled into another person's lungs and multiply, that person may contract TB.
The bacteria may also enter the body through skin wounds, including tattoos and body piercings with unsterilized insturments.
Via droplet infection
Is Tuberculosis as deadly as the black death?
While Tuberculosis is a serious, contagious, and potentially deadly disease if left untreated. In is not as serious as the black death, which is commonly believed to have been a strain of Y. pestis bacteria. Tuberculosis, even when transmitted, often results in a latent, asymptomatic form that does not lead to active infection, and among the actively infected the progress of the disease is much slower than plague.
Y. pestis, in comparison, which causes bubonic, septicemic, and pneumonic plague, can kill up to two of every three infected without treatment and can cause death with days. The major outbreaks of plague are among the worst pandemics in human history.
What conditions in the ghettos and concentration camps caused tuberculosis to spread?
The combined effects of malnutrition and severe overcrowding meant that infectious diseases spread easily. Moreover, there was no medication in the camps and ghettos.
How do you catch tuberculosis?
It is caused by Mycobacterium tuberculosis. It is transmitted from person to other by droplet nuclei which are aerosolized by coughing,sneezing and speaking.
How is a tuberculosis test confirmed?
Redness alone at the skin test site usually means you have not been infected with TB bacteria. A firm red bump may mean you have been infected with TB bacteria at some time. The size of the firm bump (not the red area) is measured 2 to 3 days after the test to determine the result.
Why is tuberculosis considered a reemerging virus?
TB is caused by a bacteria not a virus. But we more or less thought that we "won the war" but it has changed and became dangerous again by adapting. Something called evolution. Our medications have actually selected for hardier strains.
Which TB tine test requirements are soldiers expected to perform during post deployment?
They are expected to perform Initial & 90 day TB tine tests.
Why is a patient with tuberculosis often noncompliant with treatment?
Due to the time length of treatment, the patient may stop taking their medication when they start feeling better.
It take 12 months to treat.
Can a person live with one lung who has tuberculosis?
no it is not possible that an person can live with out one lung
AMyloidosis
What is bone marrow tuberculosis?
if you have it, go see your doctor and say that you have the rare "Tarkyurter" tuber. Also before you go, have 1 pound of sugar. It is a fatal disease that typically ruins your lungs.
What is the gold standard for diagnosis of tuberculosis?
The Löwenstein-Jensen culture method is regarded as the gold standard for diagnosing TB, Dr. Moore and colleagues noted in the Oct. 12 issue of the New England Journal of Medicine. It is highly accurate but takes up to six weeks to deliver a result.
In a large scale, operational test in Peru, the microscopic-observation drug-susceptibility (MODS) assay out-performed two reference methods, automated mycobacterial culture and culture on Löwenstein-Jensen medium, according to David Moore, M.D., of Imperial College London.
By contrast, the median time in this study for the new method to deliver a result was seven days, the researchers said, and its accuracy was significantly better than the Löwenstein-Jensen culture method.
An additional benefit is that it can immediately detect drug resistance, Dr. Moore and colleagues said, allowing more effective treatment from the beginning.
"New diagnostic tools are urgently needed to detect TB and multidrug-resistant TB," said Robert Gilman, M.D., of Johns Hopkins University Bloomberg School of Public Health, a co-author.
"MODS is just such a tool," Dr. Gilman said. "It will change the practice of TB testing in developing countries."
The MODS assay is based on three principles, the researchers said: that Mycobacterium tuberculosis grows faster in a liquid medium than in solid, that the characteristic cord formation can be seen early through a microscope, and that adding TB drugs to part of the culture allows direct drug-susceptibility testing at the same time.
Preliminary work on the assay showed it was able to distinguish TB patients from healthy controls. For this study, the researchers looked at three cohorts populations in Peru. These were unselected patients with suspected tuberculosis seen at 10 government clinics in Lima, patients at high-risk of TB or multidrug-resistant TB seen at five separate clinics, and unselected patients admitted to two Lima hospitals for HIV infection.
In this study, technicians using the assay placed liquid culture from sputum samples in 12 wells of a 24-well tissue-culture plate. Four of the wells contained only the culture and the remaining eight wells contained one of four TB drugs in one of two concentrations.
