Is shigella dysentery acid fast positive?

No, Shigella dysentery is not acid-fast positive. Shigella is a genus of bacteria that are Gram-negative and do not retain the stain used in acid-fast bacilli (AFB) staining. Acid-fast positivity is characteristic of mycobacteria, such as Mycobacterium tuberculosis, not Shigella. Therefore, Shigella dysentery would not be identified as acid-fast in laboratory tests.
