Coincidental appearance of PKD and Sphaerospora sp. (Myxosporidia) in stock of Salmo gairdneri (Osteichthyes)
TLDR
Neither the exact identification of the Sphaerospora species has been possible, nor the final proof, whether the luminal form, the hitherto undescribed extraluminal forms and PKX belong to one another.Abstract:
For the first time in Europe simultaneous occurrence of PKX and Sphaerospora sp. is recorded in Salmo gairdneri. Myxosporidian (?) forms hitherto not described have been observed in the kidney interstitium and the epithelium of the renal tubules, sporadically also in the swimbladder wall and the intestinal wall, besides the typical PKX organism in the kidney interstitium. Sporogonic stages and spores of a Sphaerospora species have been found in the lumen of the renal tubules. Neither the exact identification of the Sphaerospora species has been possible, nor the final proof, whether the luminal form, the hitherto undescribed extraluminal forms and PKX belong to one another.read more

Tetracapsula renicola n. sp. (myxozoa:saccosporidae); the pkx myxozoan—the cause of proliferative kidney disease of salmonid fishes
TL;DR: These analyses and those of others, along with phenotypic observations, indicate that salmonid fishes are the primary myxosporean hosts for PKX, that the cryptic spores of PKX in salmonids are the fully formedMyxospores as they occur in the fish host, and that PKX represents distinct species that was previously place in the genus Tetracapsula in the family Saccosporidae.

Ribosomal DNA Sequence Analysis of Isolates of the PKX Myxosporean and Their Relationship to Members of the Genus Sphaerospora
TL;DR: With these primers, a portion of the SSU rDNA of PKX was amplified and sequenced from the kidneys of infected salmonids from British Columbia, Washington, California, Newfoundland, and England, indicating that PKX isolates from dif...

Comparative studies of PKX and Sphaerospora spp. from salmonids using lectin and monoclonal antibody staining techniques.
TL;DR: The results of the lectin and monoclonal staining of PKX and Sphaerospora oncorhynchi indicated that further work was required to prove or disprove the hypothesis that PKZ and S, oncorHynchi are the same organism.

Light and electron microscope observations on extrasporogonic and sporogonic stages of a myxosporean parasite of the genus Sphaerospora Thelohan, 1892 from Atlantic salmon, Salmo solar L., in Scotland
TL;DR: In this article, the development of both extrasporogonic and sporogonic stages was studied by light and transmission electron microscopy, and they were found to be disporous and occurred later in the kidney tubules.
