Topic overview

Start with the big picture

The lesson is organized into fungi, protozoa, and helminths. Fungal examples include Candida, Aspergillus, Cryptococcus, and Pneumocystis, with attention to forms such as budding yeast, septate hyphae, and silver-stain cysts, alongside associated syndromes and treatments. Protozoal infections include malaria, toxoplasmosis, amebiasis, giardiasis, leishmaniasis, and Chagas disease; their clinical patterns range from cyclic fever to dysentery and cardiac involvement. The helminth section highlights schistosomiasis and neurocysticercosis. Across the topic, distinguishing clues include exposure history, characteristic organ involvement, and microscopy findings such as trophozoites containing red blood cells. These connections provide a framework for recognizing major infections and their commonly listed therapies.
