Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, [7] is a contagious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. [1] Tuberculosis generally affects the lungs, but it can also affect other parts of the body. [1]
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [ 1 ] [ 2 ] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
Microorganisms transmitted by airborne transmission include Legionella, Mycobacterium tuberculosis and the rubeola and varicella viruses. Common vehicle transmission This applies to microorganisms transmitted to the host by contaminated fomite items, such as food, water, medications, devices, and equipment. Vector borne transmission
Ultimately, though, TB can avoid the mucus traps and make its way to the deep airways and alveoli where we have macrophages which eat up foreign cells, digest, and destroy them. With TB, they recognize foreign proteins on their cell surface, and phagocytize them, or essentially package them into a space called a phagosome.
Fecal–oral transmission is primarily considered as an indirect contact route through contaminated food or water. However, it can also operate through direct contact with feces or contaminated body parts, such as through anal sex. [19] [20] It can also operate through droplet or airborne transmission through the toilet plume from contaminated ...
Those colored shapes are called “printer’s color blocks” or “process control patches,” and they’re there to help the printing team who prints the food packaging.
Latent tuberculosis (LTB), also called latent tuberculosis infection (LTBI) is when a person is infected with Mycobacterium tuberculosis, but does not have active tuberculosis (TB). Active tuberculosis can be contagious while latent tuberculosis is not, and it is therefore not possible to get TB from someone with latent tuberculosis.
