Cysts of Iodamoeba butschlii are characterized by which feature?

Cysts of Iodamoeba butschlii are characterized by which feature?

• A. Chromatoidal bars with rounded ends
• B. A heavily vacuolated cytoplasm
• C. A large glycogen vacuole
• D. Many ingested bacteria and yeast cells

Answer: (C)

Iodamoeba butschlii cysts are distinctive due to the presence of a large glycogen vacuole, which is a key identifying feature. This glycogen vacuole is responsible for the notable appearance of these cysts under the microscope, often giving them a prominent outline. The presence of the glycogen vacuole is significant because it reflects the organism’s metabolic capability and serves as an important storage form of energy that can be utilized in nutrient-deficient environments. While the other features mentioned, such as chromatoidal bars or vacuolated cytoplasm, can be associated with other protozoan cysts, they do not characterize Iodamoeba butschlii specifically. Understanding these distinguishing features is crucial in microbiology for the identification and differentiation of pathogenic organisms.
