Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.
MTB can withstand weak disinfectants and survive in a dry state for weeks. In nature, the bacterium can grow only within the cells of a host organism, but M. tuberculosis can be cultured in the laboratory. [58] Using histological stains on expectorated samples from phlegm (also called sputum), scientists can identify MTB under a microscope.
It doesn’t just survive, though, it proliferates, and creates a localized infection. At this point somebody has developed primary tuberculosis, which means that they have signs of infection soon after being exposed to TB. Even though it sounds bad, most people at this stage are actually asymptomatic or maybe have a mild flu-like illness.
M. tuberculosis can also grow on the lipid cholesterol as a sole source of carbon, and genes involved in the cholesterol use pathway(s) have been validated as important during various stages of the infection lifecycle of M. tuberculosis, especially during the chronic phase of infection when other nutrients are likely not available. [47]
It is the primary lipid found on the exterior of M. tuberculosis cells. [1] Cord factor influences the arrangement of M. tuberculosis cells into long and slender formations, giving its name. [2] Cord factor is virulent towards mammalian cells and critical for survival of M. tuberculosis in hosts, but not outside of hosts.
Mycobacterium marinum is an acid-fast, aerobic bacterium which can infect humans. [4] Infection is usually associated either with swimming, preparing sea food, or with keeping or working with aquarium fish. [2] Infections of humans are rare due to the chlorination of water. [4]
Infected people generate larger droplets and aerosols which can infect over longer distances. A poster outlining precautions for airborne transmission in healthcare settings. It is intended to be posted outside rooms of patients with an infection that can spread through airborne transmission. [1]
Persons with HIV and latent tuberculosis have a 10% chance of developing active tuberculosis every year. "HIV infection is the greatest known risk factor for the progression of latent M. tuberculosis infection to active TB. In many African countries, 30–60% of all new TB cases occur in people with HIV, and TB is the leading cause of death ...
