gather in the alveolar sacs. Once in the alveolar sacs, the
bacteria begin to multiply. The body'' s body immune system starts
working as well as macrophages begin to surround the germs. A granuloma is created to maintain
the bacteria from spreading.The TB microorganisms
stay in the
lungs, however the body is secured from disease by the
granuloma. In 8 to 10 weeks,

infection to TB illness occurs when the granuloma break open
and the TB microorganisms multiply. After that the person becomes
unwell with TB illness as well as may be contagious. This development can take place
instantly after infection, several years later, or otherwise at all. When the TB gets away
from the granuloma and begins damaging an individual'' s. lungs it ' s called pulmonary TB. TB germs can also enter.
