Accepted Answer

The acid-fast bacillus, also known as Mycobacterium tuberculosis, is most often spread through droplet infection when an infected person coughs or sneezes. It is not eradicated by a single dose of penicillin and can cause disease in animals as well as humans. While it can be diagnosed through various methods, such as sputum or blood cultures, diagnosis through urine culture is not common.
