Microsporidia

ALSO KNOWN AS: Microsporidiosis

Microsporidia are intracellular parasitic fungi that infect a wide range of fish species. They primarily affect muscle, gills, and internal organs, leading to cyst formation, tissue damage, and reduced fish health. Some infections can cause severe deformities and mortality, especially in aquaculture settings. Transmission occurs through ingestion of spores from infected tissues or contaminated water.

Distribution: Worldwide

Hosts: Freshwater and marine fish species

Detection Methods: Microscopic examination of infected tissues, Histopathology, PCR testing

Target Tissue: Muscle, gills, internal organs
