Guida verificata passo dopo passo1
Step 1: Identify the genus Shigella and recall its general characteristics in microbiology, focusing on morphology, Gram stain reaction, motility, and pathogenicity.
Step 2: Understand that Shigella species are Gram-negative rods, meaning they appear pink/red after Gram staining and have a rod-shaped morphology.
Step 3: Recognize that Shigella species are non-motile, which means they do not have flagella and cannot move independently.
Step 4: Recall the clinical significance of Shigella, which is primarily associated with causing bacillary dysentery, an infectious disease characterized by severe diarrhea.
Step 5: Compare the given options with these known characteristics to determine which statement accurately describes Shigella species.
