Acid Fast Bacillus Test
The acid-fast bacillus (AFB) test is a diagnostic method used to detect bacteria that cause infections like tuberculosis. The test involves staining a sample, typically sputum, with special dyes that allow certain bacteria to retain color even after being washed with acid.
This unique property helps identify the presence of acid-fast organisms under a microscope. Accurate detection is crucial for early diagnosis and treatment, helping prevent the spread of infectious diseases.

Yeah that’s pretty much it! The BCG vaccine is the main one they use — it’s been around forever and works really well for kids especially. For adults it’s a bit hit or miss though.
The thing is, if you actually get TB the vaccine won’t cure it — you’d still need a full round of antibiotics which can take like 6 months or more. The vaccine is really just there to prep your immune system beforehand.
They’re also working on better vaccines since the current one has its limits. But overall you summed it up pretty well!
