MYCOBACTERIUM
TUBERCULOSIS
one of the most well-known and studied bacteria
due to its role in causing tuberculosis (TB), a highly
contagious and deadly disease that primarily affects
the lungs but can also target other organs, its also a
drug resistant disease.
PATHOGENESIS OF TUBERCULOSIS
1. Infection Process: enters by respiratory tract when an
infected person sneeze or cough then it travels to the
lungs.
2. Granuloma Formation: M. tuberculosis can remain
dormant within granulomas for years, making it difficult
for the immune system to clear the infection.
PHYSICAL APPERANCE
Acid-fast staining:red or pink under the microscope
when stained using the Ziehl-Neelsen stain or acid-
fast stain
Rod-shaped bacteria
Clustered
