Study Notes

Intestinal Flukes

Fasciolopsis buski: Large intestinal fluke that causes Fasciolopsiasis, transmitted through ingestion of infected water plants with metacercariae by humans or pigs.
Symptoms: Abdominal discomfort, irritation, inflammation, bleeding, jaundice, diarrhea, gastric discomfort, edema, and malabsorption syndrome.
Treatment: Praziquantel.

Liver Flukes

Fasciola hepatica: Sheep liver fluke that causes Fascioliasis, transmitted through ingestion of metacercariae on vegetation by definitive hosts.
Symptoms: Headache, fever, chills, pain in the liver area, eosinophilia, jaundice, liver tenderness, anemia, diarrhea, and biliary obstruction.
Treatment: Praziquantel or bithionol.

Chinese Liver Fluke

Clonorchis sinensis: Causes Clonorchiasis, transmitted through ingestion of pickled freshwater fish and shrimp.
Symptoms: Fever, abdominal pain, eosinophilia, diarrhea, anorexia, epigastric discomfort, occasional jaundice, and enlarged and tender liver.
Treatment: Praziquantel or albendazole.

Heterophid Flukes

Heterophyes heterophyes: Heterophid fluke that causes Heterophyiasis, transmitted through ingestion of undercooked fish containing metacercariae.
Symptoms: Abdominal pain, eosinophilia, diarrhea, and gastrointestinal discomfort.
Treatment: Praziquantel.

Oriental Lung Fluke

Paragonimus westermani: Causes Paragonimiasis and pulmonary distomiasis, transmitted through ingestion of freshwater products.
Symptoms: Cough, fever, chest pain, blood-tinged sputum, chronic bronchitis, eosinophilia, and fibrous tissue production.

Blood Flukes

Schistosoma spp.: Causes Schistosomiasis, bilharziasis, swamp fever, and Katayama fever, transmitted through cercariae penetrating the skin.
Symptoms: Abdominal pain, fever, chills, cough, diarrhea, eosinophilia, and painful urination and hematuria.
Treatment: Praziquantel, oxamniquine, or surgery.
