Intraspecific genetic diversity of the fish-infecting microsporidian parasite Pseudokabatana alburnus (Microsporidia)

Abstract: Pseudokabatana alburnus is a xenoma-forming fish microsporidium, firstly described from the liver of the Culter alburnus from Poyang Lake in China. In the present study, P. alburnus was firstly reported from the ovary of 6 other East Asian minnows, including Squaliobarbus curriculus, Hemiculter leucisculus, Cultrichthys erythropterus, Pseudolaubuca engraulis, Toxabramis swinhonis, and Elopichthys bambusa. Genetic analysis revealed high sequence diversity in the ribosomal internal transcribed spacer region (ITS… Show more

“…They are characterized by the production of infective spores which transmit the infective sporoplasm to the host cytoplasm or nucleoplasm by a unique complicated eversion apparatus-polar tube yet exhibit a closer phylogenetic affinity to fungi [ 3 , 4 , 5 ]. Over 160 species across 22 genera have been identified in fish [ 6 , 7 ], and new species are continuously emerging [ 8 , 9 , 10 ]. Many microsporidians pose a significant threat to pisciculture.…”

“…About 220 Microsporidia genera are known to infect aquatic organisms, among which more than 160 species falling within 22 genera are known to infect fishes (Liu et al, 2019). Some of the most economically important microsporidia species that infect fish are Glugea, Loma, Pleistophora, Enterocytozoon and Nosema (Picard-Sánchez et al, 2021; Weng et al, 2023) . The diagnosis of microsporidia dependent on the small subunit (SSU) rDNA sequencing molecular phylogeny beside spore morphological characters is becoming important for the classification and characterization of the microsporidia (Abdel-Baki et al, Mansour et al, 2020).…”
