U01.03.017 Bacteria with exotoxins Review each clinical case carefully. Identify the bacterium responsible for the described condition and match it with its pathogenesis mechanism. Use the given clues such as age, symptoms, exposure history, and toxin effects to determine the correct answer. Then drag and drop each bacterium and its corresponding pathogenesis into the correct boxes. This exercise reinforces your understanding of bacterial toxins, virulence factors, and disease presentations — high-yield for USMLE Step 1 and Step 2.

U01.03.016 Features of exotoxins and endotoxins Match each bacterial exotoxin to its causative organism and mechanism of pathogenesis. Focus on how these toxins act at the cellular level — whether they block neurotransmission, inhibit protein synthesis, or alter intracellular signaling (like cAMP). Understanding these mechanisms is essential for mastering microbiology concepts in USMLE Step 1 and clinical reasoning.
