Abstract

Two myxozoan species were observed in the kidney of topsmelt, Atherinops affinis, during a survey of parasites of estuarine fishes in the Carpinteria Salt Marsh Reserve, California. Fish collected on three dates in 2012 and 2013 were sectioned and examined histologically. Large extrasporogonic stages occurred in the renal interstitium of several fish from the first two collections (5/8, 11/20, respectively), and, in some fish, these replaced over 80% of the kidney. In addition, presporogonic and polysporogonic stages occurred in the lumen of the renal tubules, collecting and mesonephric ducts. The latter contained subspherical spores with up to 4 polar capsules, consistent with the genus Chloromyxum. For the third collection (15 May 2013, n=30), we portioned kidneys for examination by histology, wet mount, and DNA extraction for small subunit ribosomal gene sequencing. Histology showed the large extrasporogonic forms in the kidney interstitium of 3 fish, and 2 other fish with subspherical myxospores in the lumen of the renal tubules with smooth valves and two spherical polar capsules consistent with the genus Sphaerospora. Chloromyxum-type myxospores were observed in the renal tubules of one fish by wet mount. Sequencing of the kidney tissue from this fish yielded a partial SSU rDNA sequence of 1769 bp. Phylogenetic reconstruction suggested this organism to be a novel species of Chloromyxum, most similar to Chloromyxum careni (84% similarity). In addition, subspherical myxospores with smooth valves and two spherical polar capsules consistent with the genus Sphaerospora were observed in wet mounts of 2 fish. Sequencing of the kidney tissue from 1 fish yielded a partial SSU rDNA sequence of 1937 bp. Phylogenetic reconstruction suggests this organism to be a novel species of Sphaerospora most closely related to Sphaerospora epinepheli (93%). We conclude that these organisms represent novel species of the genera Chloromyxum and Sphaerospora based on host, location, and SSU rDNA sequence. We further conclude that the formation of large, histozoic extrasprogonic stages in the renal interstitium represent developmental stages of the Chloromyxum species for the following reasons: 1. Large extrasporogonic stages stages were only observed in fish with Chloromyxum-type spores developing within the renal tubules, 2. DNA sequence consistent with the Chloromyxum sp. was only detected in fish with the large extrasporogonic stages and 3.Sphaerospora species have extrasporogonic forms, but they are considerably smaller and are comprised of much fewer cells.

Attention Score in Context

This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 April 2017.
All research outputs
#4,893,202
of 16,009,751 outputs
Outputs from Journal of Parasitology
#387
of 2,348 outputs
Outputs of similar age
#71,610
of 235,539 outputs
Outputs of similar age from Journal of Parasitology
#6
of 20 outputs
Altmetric has tracked 16,009,751 research outputs across all sources so far. This one has received more attention than most of these and is in the 68th percentile.
So far Altmetric has tracked 2,348 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one has done well, scoring higher than 83% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 235,539 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
We're also able to compare this research output to 20 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
