Describe the intended learning outcomes related to knowledge and understanding of trematodes.
The intended learning outcomes related to knowledge and understanding of trematodes include describing common parasitic diseases caused by trematodes, their life cycle, pathogenesis, clinical features, differential diagnosis, complications, and the principles of management for common parasitic trematode diseases.
What intellectual skills are associated with the study of trematodes?
The intellectual skills associated with the study of trematodes include assessing the differentiation between the behavior and ecology of different parasite species and stages in the environment, as well as diagnosing different trematodes.
List the professional and practical skills related to the study of trematodes.
The professional and practical skills related to the study of trematodes include collecting different samples for different techniques, methods of isolation and identification of parasites, diagnosing some parasitic infections in different hosts, and using advanced techniques in diagnosis.
Explain the methods of recovery of parasites and their culture methods as well as immunological and molecular methods used for diagnosis of parasitic infections.
The methods of recovery of parasites include techniques such as stool examination, while culture methods involve growing parasites in appropriate media. Immunological methods for diagnosis include serological tests, and molecular methods involve techniques like PCR for parasite detection.
What are the principles of management for common parasitic trematode diseases?
The principles of management for common parasitic trematode diseases include antiparasitic medications, supportive care for complications, and public health measures to prevent transmission.
How would you carry out protection of society and environment from pollution with parasites?
Protection of society and environment from pollution with parasites involves implementing measures such as proper sanitation, waste management, and control of intermediate hosts.
What are the methods of prevention and control for the infection of trematodes?
Treatment of the patient and reservoir host, avoiding eating intermediate hosts such as fish, avoiding contact with infected water or stool, avoiding eating improperly cooked liver or unwashed vegetables, sanitary sewage disposal, and formatting health education programs.
What is the general characteristic of the body surface of trematodes?
It comprises a tough syncytial tegument which protects against the digestive enzymes of the host, and it is also the surface of gas exchange.
What are the organs of attachment in adult trematodes?
Oral sucker surrounding the mouth, ventral sucker on the ventral surface of the body, and genital sucker (present in some species).
How do trematodes excrete waste material?
There is no anus, and waste material is egested through the mouth.
What is the characteristic of the eggs of trematodes?
The eggs of trematodes are operculated except for Schistosomes.

Where does the life cycle of trematodes pass through sexual development?
Inside the definitive host.
What are the geographical distributions of Intestinal Fluke Heterophyes heterophyes?
Fish-eating countries, Egypt, China, India, Iran, Israel, Japan, Korea, Sudan, Taiwan, the Philippines, Tunisia, and Turkey.
In which habitat does Intestinal Fluke Heterophyes heterophyes reside?
Small intestine.
