Answer 1

Tuberculosis I think is the answer

Answer 2

Answer:

(a) M. tuberculosis is an acid-fast bacteria.

Explanation:

Acid-fast staining, also known as Ziehl-Neelsen staining, is a method for identifying bacteria that are resistant to simple or Gram staining, such as members of the genus Mycobacterium, and can only be seen with acid-fast staining.

The AFB smear's basis is based on the fact that AFB's cell walls contain mycolic acid, which makes them resistant to acid alcohol decolorization. As a result, when culture and antibiotic susceptibility testing (AST) is unavailable, it provides a quick and low-cost alternative to tuberculosis (TB) testing.
