What type of agent is tuberculosis?
Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain.
Is tuberculosis an infectious agent?
Tuberculosis (TB) is a contagious disease caused by infection with Mycobacterium tuberculosis (Mtb) bacteria. It is spread through the air when a person with TB disease of the lungs or throat coughs, speaks or sings, and people nearby breathe in these bacteria and become infected.
Is tuberculosis airborne or droplet?
tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. TB is spread from person to person through the air.
What is tuberculosis biology?
tuberculosis: An infectious disease of humans and animals caused by a species of mycobacterium mainly infecting the lungs where it causes tubercles characterized by the expectoration of mucus and sputum, fever, weight loss, and chest pain. It is transmitted through inhalation or ingestion of bacteria.
How long does TB droplets stay in the air?
M. tuberculosis can exist in the air for up to six hours, during which time another person may inhale it.
Is it safe to be around someone with TB?
It is important to know that a person who is exposed to TB bacteria is not able to spread the bacteria to other people right away. Only persons with active TB disease can spread TB bacteria to others. Before you would be able to spread TB to others, you would have to breathe in TB bacteria and become infected.
Which is infectious agent causes tuberculosis ( TB ) ( consumption )?
Mycobacterium tuberculosis, a tubercle bacillus, is the causative agent of TB. It belongs to a group of closely related organisms—including M africanum, M bovis, and M microti —in the M tuberculosis complex. (See Etiology .)
What are the risks of taking a biologic agent for TB?
The risk of TB associated with different biologics varies significantly, with the highest relative risks, 29.3 and 18.6, associated with adalimumab and infliximab, respectively. The risk of TB with newer TNF-α inhibitors and other biologics appears to be lower.
What kind of agents are used in biological therapy?
The agents used in this method include interferons and interleukins ( IL-2 and IL-12, for example), as well as bacillus (or bacilli) Calmette-Guerin ( BCG ), the organism that causes tuberculosis. The immune response to tuberculosis can cause certain cancers to regress.
What kind of drugs are used to treat tuberculosis?
PAS, Fluoroquinolones, Cyclic Peptides and Aminoglycosides act on the DNA. Tuberculosis drugs target various aspects of Mycobacterium tuberculosis biology, including inhibition of cell wall synthesis, protein synthesis, or nucleic acid synthesis.
