Challenges
in the Aquaculture System
Enterocytozon hepatopenaei (EHP) infects the shrimp hepatopancreas
Significant economic losses in shrimp aquaculture
Benefits
Innovative Solution to Control EHP Challenges
Controls the parasite load, reduces parasite impact on host performance
Optimizes animal welfare, improves environmental conditions
Improves economical results
EHP (Enterocytozoon hepatopenai) dapat ditularkan dari lingkungan external maupun secara horizontal dari udang ke udang
Germinasi polar tube
Microsporidian:
size less than 1 μm
Infeksi akibat polar tube
Spora memperbanyak diri
Spora terlepas ke lingkungan
EHP Infestation Cycle
Microsporidian:
size less than 1 μm
1.
Bind and disrupt parasite membranes
2.
Abrasive & desiccating effect slices and dehydrates parasites
3.
Breaks the outer wall of parasites, making them vulnerable to host immunity
