“…Some fish-infecting microsporidians are economically important pathogens for wild and aquaculture fish, such as Glugea pagri infecting the red sea bream Pagrus major (Su et al, 2014), Enterospora epienpheli infecting the juvenile groupers Epinephelus spp. (Xu et al, 2017), and G. plecoglossi infecting the ayu Plecoglossus altivelis (Zhou et al, 2018). The early classification of microsporidia was mainly based on spore morphological characteristics and ultrastructural features of the life developmental stages.…”

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) and the largest subunit of RNA polymerase II (Rpb1) loci of P. alburnus isolated from different hosts and locations. The variation of Rpb1 mainly occurred in the 1,477–1737 bp regions. The presence of a wide variety of Rpb1 haplotypes within a single fish host, together with evidence of genetic recombination suggested that P. alburnus may have the intergenomic variation and sexual reproduction might be present in other hosts (possibly freshwater shrimp). Phylogenetic analysis and population genetic analysis showed that there was no geographical population divergence for P. alburnus. Homogeneity and high variability of ITS sequences indicates that ITS may be a suitable molecular marker to distinguish different P. alburnus isolates. Our data confirm the broad geographical distribution and host range of P. alburnus in the middle and lower reaches of the Yangtze River. Additionally, we emendated the genus Pseudokabatana to exclude the infection site, liver as one of the taxonomic criteria, and proposed that fish ovary was be the general infection site of P. alburnus.

“…Microsporidiosis has been attracted increasing concerns in aquaculture worldwide for some of them has been increasingly found to cause severe economic losses to the culture of crustaceans and fish, like glugeasis in ayu, Plecoglossus altivelis altivelis , enteric microsporidiosis in juvenile groupers, Epinephelu s spp. and hepatopancreatic microsporidiosis in penaeid shrimp (Chaijarasphong et al, 2021; Xu et al, 2017; Zhou et al, 2017). Ameson portunus (Microsporidia, Glugeida) is the causative microsporidian agent of recently outbreak ‘toothpaste‐like syndrome’ of pond‐cultured swimming crab, Portunus trituberculatus in China (Wang et al, 2017).…”
