Form and Function in the Digenea, with an Emphasis on Host-Parasite and Parasite-Bacteria Interactions

Area of Science:

• Helminthology
• Parasitology
• Comparative Anatomy

Background:

• Digenetic trematodes are significant parasites with complex body systems.
• Understanding their physiology is crucial for host-parasite interaction studies.
• Recent advancements necessitate an updated review of their biology.

Purpose of the Study:

• To provide a comprehensive overview of digenetic trematode anatomy and physiology.
• To highlight new knowledge and recent advances since 2019.
• To discuss the role of bacteria and novel control strategies.

Main Methods:

• Literature review of recent scientific publications.
• Synthesis of information on major body systems (tegumentary, sensory, neuromuscular, digestive, excretory, reproductive).
• Inclusion of data on bacterial roles and emerging control methods.

Main Results:

• Key advances in the morphology and physiology of digenetic trematode systems are reported.
• The known and putative roles of bacteria in digenean biology are discussed.
• Current trends in treatment and control strategies are presented.

Conclusions:

• Updated knowledge of digenetic trematode systems enhances understanding of host-parasite interactions.
• The role of symbiotic bacteria is increasingly recognized as important.
• A deeper understanding of trematode biology informs novel control strategies.
