Diarrhea: Microbiology & Pharmacology

Diarrhea is a common condition caused by bacteria (e.g., E. coli, Salmonella), viruses (e.g., Rotavirus, Norovirus), and protozoa (e.g., Giardia, Entamoeba). Treatment depends on etiology and may include rehydration, antibiotics, antiprotozoals, or antidiarrheals. Understanding the microbiology and pharmacological interventions is essential for clinical practice.
