Recent Advances in Our Knowledge of the Myxozoa
Michael L. Kent,Karl B. Andree,Jerri L. Bartholomew,Mansour El-Matbouli,Sherwin S. Desser,Robert H. Devlin,Stephen W. Feist,Ronald P. Hedrick,Rudolf W. Hoffmann,Jaswinder Khattra,Sascha L. Hallett,Robert J. G. Lester,Matt Longshaw,Oswaldo Palenzeula,Mark E. Siddall,Chongxie Xiao +15 more
TL;DR: It is indicated that the Myxozoa are closely related to Cnidaria, and marine taxa at the genus level branch separately from genera that usually infect freshwater fishes; taxa cluster more by development and tissue location than by spore morphology.
Journal ArticleDOI
Ultrastructure and small-subunit ribosomal DNA sequence of Henneguya lesteri n. sp. (Myxosporea), a parasite of sand whiting Sillago analis (Sillaginidae) from the coast of Queensland, Australia.
Sascha L. Hallett,Ariel Diamant +1 more
TL;DR: Henneguya lesteri is the first marine species of HenneguYA to be characterized at the molecular level: 1966 bp of the small-subunit (18S) rDNA is determined, and results indicated that differences between this and the hitherto studied freshwater HenneGuya species are greater than differences among the freshwater HenNEguya species.
Journal ArticleDOI
Application of a real-time PCR assay to detect and quantify the myxozoan parasite Ceratomyxa shasta in river water samples.
TL;DR: The QPCR methodology was utilised to investigate the temporal and spatial distribution of C. shasta in the Klamath River, Oregon/ California and found the parasite was detected throughout the river, and 2 of 5 tributaries tested contributed parasites to the mainstem.
Journal ArticleDOI
Involvement of manayunkia speciosa (annelida: polychaeta: sabellidae) in the life cycle of parvicapsula minibicornis, a myxozoan parasite of pacific salmon
TL;DR: This coelomic myxozoan infection was detected in freshwater polychaetes, Manayunkia speciosa from the Klamath River, Oregon/California, a site enzootic for the myXozoan parasites Ceratomyxa shasta and Parvicapsula minibicornis.
Journal ArticleDOI
Density of the Waterborne Parasite Ceratomyxa shasta and Its Biological Effects on Salmon
Sascha L. Hallett,R. Adam Ray,Charlene N. Hurst,Richard A. Holt,Gerri R. Buckles,Stephen D. Atkinson,Jerri L. Bartholomew +6 more
TL;DR: Direct quantification of the density of host-specific parasite genotypes in water samples offers a management tool for predicting host population-level impacts of the myxozoan parasite C. shasta.
