Essay on epidemiology of tuberculosis: in the late 1980s, tb began re-emerging and now globally, kills more than 2 million people each year it is thought that as many as 2 billion people have been exposed to the tb bacillus and are therefore at risk of developing the active disease. Mycobacterium tuberculosis (mtb), the bacterium that causes tuberculosis in humans, infects roughly two billion people worldwide however, less than one percent of infected individuals are symptomatic most have a latent infection characterized by dormant, non-replicating bacteria that persist.

Mycobacterium tuberculosis (mtb) is an etiological agent or pathogenic bacteria that cause most of the tuberculosis it is a small rod shaped bacillus which can survive in a dried or disinfected state for several weeks thanks to its thick lipid cell wall.
Mycobacterium tuberculosis pathogenesis and molecular determinants of virulence advantage to mouse experiments is that there are inbred strains that show widely different levels of resistance to m tuberculosis and other pathogens, while these methods had some success in investigating m tuberculosis, the process was still difficult. In some cases this is harmless, but the ability of tuberculosis to survive treatment and spread makes diagnosing and understanding infections vital to combatting its lethality and global prevalence tuberculosis is a highly infectious disease, and is primarily transmitted via inhalation of aresol droplets expelled by infected hosts.
