Fungal Phylum Microsporidia

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Parasitology
Aquaculture

Background:

Microsporidia are increasingly recognized as significant pathogens in fish.
Finfish aquaculture growth and zebrafish research amplify concerns about microsporidiosis.
Understanding fish microsporidia is crucial for aquatic health and research.

Purpose of the Study:

To provide an updated review of Microsporidia in fishes since 2013.
To cover new taxa, hosts, diseases, and diagnostic advances.
To discuss broader impacts and transmission dynamics of fish microsporidia.

Main Methods:

Literature review of scientific publications since 2013.
Synthesis of data on new Microsporidia species and fish hosts.
Analysis of research on diagnostic methods and disease impacts.

Main Results:

Identification of novel Microsporidia taxa and associated fish hosts.
Documentation of emerging microsporidian diseases in wild and captive fish.
Advances in molecular and morphological diagnostic techniques for fish microsporidia.

Conclusions:

Microsporidiosis poses a growing threat to fish health in aquaculture and research settings.
Further research is needed on transmission, invertebrate hosts, and phylogenetics.
Updated knowledge is essential for effective disease management and mitigation strategies.
