What is the morphology for shigella flexneril?
Shigella flexneri is a Gram-negative bacterium characterized by its rod-shaped morphology. It typically measures about 0.5 to 0.7 micrometers in diameter and 1 to 3 micrometers in length. These bacteria are non-spore-forming and exhibit a single polar flagellum, although many strains are non-motile. Shigella flexneri is known for its ability to cause dysentery in humans.
What is shigella dysenteriae gram stain?
Negative
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.
