The Sea Cucumber‐Infecting Parasite Apostichocystis gudetama gen. nov. sp. nov. Expands Marine‐Host‐Specific Clade of Apicomplexans

ABSTRACT Unknown ellipsoid bodies, later classified as apicomplexan cysts, are prevalent in the ovaries of Japanese sea cucumbers ( Apostichopus japonicus ), where they can lead to lower fecundity infected individuals and adverse effects on wild populations well aquaculture efforts for this endangered species. Apicomplexans widespread essential marine environments, affect health fitness host populations. We performed genomic sequencing recovered cysts gain more ecological evolutionary information parasite. apicomplexan's complete nuclear ribosomal RNA rrn ) operon, entire mitochondrial genome, a partial apicoplast (relic chloroplast) genome. The operon phylogeny revealed parasite being closely related coccidian‐like parasites fish (ichthyocolids) cnidarians (corallicolids), while organelle phylogenomics hint at closer relation protococcidian Eleutheroschizon . Using new phylogenetic context previous morphological descriptions, we describe Apostichocystis gudetama gen. nov. sp. Mining available microbiomes reveal presence spp. beyond its range, alluding other potential hosts or cryptic, lineages. Its placement has important implications concerning evolution parasitism within Apicomplexa divergence marine‐host‐specific clade parasites.

Parasites as “Ecological Indicators” for Marine Vertebrates Monitoring and Ecosystem Stability

IntechOpen eBooks, Год журнала: 2024, Номер unknown

Опубликована: Дек. 19, 2024

This chapter underscores the importance of integrating parasitological data into marine monitoring programs to enhance conservation and management efforts. By leveraging parasites as ecological indicators, we can improve our understanding ecosystem dynamics promote sustainability vertebrate populations.
