Journal ArticleDOI
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
A Herpesvirus Associated with Mass Mortality of Juvenile and Adult Koi, a Strain of Common Carp
Ronald P. Hedrick,Oren Gilad,Susan Yun,J. V. Spangenberg,Gary D. Marty,R. W. Nordhausen,M. J. Kebus,Herve Bercovier,Avi Eldar +8 more
TL;DR: It is strongly suspect that this newly recognized koi herpesvirus (KHV) has the potential to be a significant cause of mortality among koi and presumably common carp.
Journal ArticleDOI
Concentrations of a Koi herpesvirus (KHV) in tissues of experimentally infected Cyprinus carpio koi as assessed by real-time TaqMan PCR.
Oren Gilad,Susan Yun,Francisco J. Zagmutt-Vergara,Christian M. Leutenegger,Herve Bercovier,Ronald P. Hedrick +5 more
TL;DR: Although there were no recognized patterns to viral DNA concentrations as found in different tissues over time, KHV genome copies for all tissues increased with time post virus exposure and with water temperature.
Journal ArticleDOI
Molecular characterization, sequence analysis, and taxonomic position of newly isolated fish iridoviruses.
TL;DR: It is demonstrated that the piscine iridoviruses examined here were members of the genus Ranavirus, and surveys of pathogenic "fish viruses" may need to include neighboring amphibian and reptilian populations, and PCR will be useful in the diagnosis of fish disease.
Journal ArticleDOI
Genome sequences of three koi herpesvirus isolates representing the expanding distribution of an emerging disease threatening koi and common carp worldwide
Takashi Aoki,Ikuo Hirono,Ken Kurokawa,Hideo Fukuda,Ronen Nahary,Avi Eldar,Andrew J. Davison,Thomas B. Waltzek,Herve Bercovier,Ronald P. Hedrick +9 more
TL;DR: The conclusion that at least some of these mutations occurred in vivo prompts the hypothesis that loss of gene functions might be associated with emergence of the disease and provides a basis for further investigations into the molecular epidemiology of the virus.
