Study Notes

Amoebiasis Prevention and Treatment

Prevent amoebiasis through practicing good hygiene, including regular handwashing and using clean water.
Metronidazole is a commonly used medication for treating amoebiasis.
Before consuming fruits and vegetables, washing them thoroughly and peeling when possible is essential for prevention.
Severe cases of amoebiasis may require hospitalization and intravenous fluids for care.

Recovery and Diagnosis

Supportive care, including hydration and proper nutrition, can improve recovery chances from amoebiasis.
Amoebiasis is primarily caused by the parasite Entamoeba histolytica.
Non-bloody diarrhea is NOT a common symptom of amoebiasis; instead, symptoms include abdominal pain, bloody stools, and fever.
Diagnosis is made through stool tests that look for E. histolytica or its cysts.

Complications and Diagnostic Tests

A life-threatening complication of amoebiasis can be amoebic dysentery or perforation of the intestine.
Microscopic examination of stool samples detects E. histolytica using a stool analysis test.

Protozoa Groups and Characteristics

Organisms in the Ciliophora group of protozoa are characterized by having cilia for movement.
The Sarcodina group includes protozoa that move using pseudopods.
Protozoa engulf food particles through a process called phagocytosis.
The Sporozoa group is defined by its parasitic nature and lack of locomotion.
Mastigophora group includes protozoa with whip-like flagella that facilitate movement and feeding.
Sarcodina organisms exhibit amorphous shapes and are characterized by their flexible cell membranes, allowing for pseudopodium formation.
Some protozoa are opportunistic feeders, adapting their diet based on the food types available.

Summary of Protozoan Feeding Mechanisms

Phagocytosis involves engulfing food particles and digesting them inside the cell.
Opportunistic feeding refers to consuming whatever food sources are available in the environment.
