Molecular and Morphological Characterization of Myxozoan Actinospore Types from a Commercial Catfish Pond in the Mississippi Delta
The morphological and molecular data generated from this study will assist in the identification of myxospore counterparts for these actinospore stages and aid in the elucidation of unknown myxozoan life cycles in closed production systems.
Characterization of the Life Cycle of a Fish Eye Fluke, Austrodiplostomum ostrowskiae (Digenea: Diplostomidae), with Notes on Two Other Diplostomids Infecting Biomphalaria havanensis (Mollusca:…

Molecularly link the cercaria, metacercari, and adult stage of the life cycle of A. ostrowskiae from the brain and eyes of several freshwater fish to identify the snail host for this parasite.
18S rRNA gene sequencing identifies a novel species of Henneguya parasitizing the gills of the channel catfish (Ictaluridae)
Based on the unique combination of pseudocyst and myxospore morphology, tissue location, host, and SSU rRNA gene sequence data, this isolate is reported to be a previously unreported species, Henneguya bulbosus sp.

Culture of hybrid catfish may be an effective management strategy to minimize the burden of PGD in farm-raised Channel Catfish and their hybrids.
Monoculture of ♀ channel ( Ictalurus punctatus ) × ♂ blue ( I. furcatus ) hybrid catfish mitigates proliferative gill disease caused by Henneguya ictaluri (Cnidaria: Myxobolidae) in…

Assessment of parasite loads in fish harvested at the termination of the study revealed H. ictaluri DNA in channel catfish to be an order of magnitude higher than hybrid catfish, which support previous work suggesting that the production of hybridCatfish may reduce PGD incidence in U.S. catfish aquaculture.

Members of the genus Clinostomum Leidy, 1856, colloquially known as yellow grubs, are cosmopolitan parasites of piscivorous birds, freshwater snails, fish and amphibians, and are endemic on most commercial catfish operations in North America.
Austrodiplostomum sp., Bolbophorus sp. (Digenea: Diplostomidae), and Clinostomum marginatum (Digenea: Clinostomidae) metacercariae in inland silverside Menidia beryllina from catfish aquaculture…
Three trematode species were characterized morphologically and molecularly by sequencing of the cytochrome c oxidase subunit 1 gene (CO1) and metacercariae were observed in both the eyes and brain of infected channel catfish, supporting molecular data that suggests the cercaria and metACercaria are both stages of a previously unidentified Austrodiplostomum sp.
Henneguya laseeae n. sp. from flathead catfish (Pylodictis olivaris) in the upper Mississippi River
A novel species of Henneguya was isolated from flathead catfish captured in the upper Mississippi River near Lansing (Allamakee County), IA, and La Crosse (La Crosse County), WI using critical morphological features, histology, and 18S ribosomal RNA gene sequence.
Myxobolus lepomis n. sp. (Cnidaria: Myxobolidae), a gill myxozoan infecting Lepomis marginatus Holbrook and Lepomis miniatus Jordan (Perciformes: Centrarchidae), in the Big Thicket National Preserve,…
These isolates are proposed as morphologically distinct, genetically conspecific representatives of M. lepomis n.
New data on Neodiplostomum americanum Chandler and Rausch, 1947 (Digenea: Diplostomidae), in the Great Horned Owl Bubo virginianus Gmelin, 1788 and the Eastern Screech Owl Megascops asio Linnaeus,…
Preliminary phylogenetic analysis of the genus based on cytochrome c oxidase subunit 1 gene sequence data supports the placement of N. americanum within a discrete phylogroup of the family Diplostomidae.
