The Mycobacterium tuberculosis complex (MTC or MTBC) is a genetically related group of Mycobacterium species that can cause tuberculosis in humans or other animals. It includes: Mycobacterium tuberculosis; Mycobacterium africanum; Mycobacterium orygis [1] Mycobacterium bovis and the Bacillus Calmette–Guérin strain; Mycobacterium microti ...
The nature of the host-pathogen interaction between humans and M. tuberculosis is considered to have a genetic component. A group of rare disorders called Mendelian Susceptibility to Mycobacterial Diseases (MSMD) was observed in a subset of individuals with a genetic defect that results in increased susceptibility to Mycobacterial infection.
The TB Structural Genomics Consortium (TBSGC) is a worldwide consortium of scientists developing a foundation for tuberculosis diagnosis and treatment by determining the three-dimensional structures of proteins from M. tuberculosis founded in 2000 as a part of the Protein Structure Initiative.
Symptoms of M. tuberculosis include coughing that lasts for more than three weeks, hemoptysis, chest pain when breathing or coughing, weight loss, fatigue, fever, night sweats, chills, and loss of appetite. M. tuberculosis also has the potential of spreading to other parts of the body. This can cause blood in urine if the kidneys are affected ...
M. tuberculosis is able to reproduce inside the macrophage and will eventually kill the immune cell. The primary site of infection in the lungs, known as the Ghon focus, is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. [13] Tuberculosis of the lungs may also occur via infection from the blood ...
H37Rv has continued to be the strain of tuberculosis most used in laboratories, and was the first to have its complete genome published in 1998. [5] It is unclear how much H37Rv may have evolved in more than 100 years under artificial conditions in laboratories from strains in the wild, but its genome is similar to a strain isolated from a 19th ...
Lipoarabinomannan, also called LAM, is a glycolipid, and a virulence factor associated with Mycobacterium tuberculosis, the bacteria responsible for tuberculosis. Its primary function is to inactivate macrophages and scavenge oxidative radicals. The inactivation of macrophages allows for the dissemination of mycobacteria to other parts of the body.
Cord factor, or trehalose dimycolate (TDM), is a glycolipid molecule found in the cell wall of Mycobacterium tuberculosis and similar species. 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]
