Parasitology (137)10 2010
Abstract
We investigated prior versus late residency within hosts, meaning which parasite contacts the host first, to determine if the outcomes of intra-host competition are altered. We infected a single genotype of the waterflea Daphnia galeata with both the intestinal protozoan Caullerya mesnili and the ha...

Abstract
We report the results of pathological, microbiological and molecular investigations used to characterize unidentified skin lesions in palmate newts (Lissotriton helveticus) from Larzac, France. We confirm that the lesions are the result of infection with a novel dermocystidium-like parasite, which i...

Abstract
These results suggest that the deterministic aspects of the epidemic process of the parasite can be quantitatively demonstrated on a 51-d timescale or longer, whereas transmission on a daily timescale is uncertain....

Abstract
Chlorine and iodine solutions were effective at inactivating Ichthyophonus spores in vitro. Inactivation in sea water increased directly with halogen concentration and exposure duration, with significant differences (P < 0.05) from controls occurring at all chlorine concentrations and exposure durat...

Journal of Parasitology (94)5 2008
Abstract
In vitro viability of Ichthyophonus spp. spores in seawater and freshwater corresponded with the water type of the host from which the spores were isolated. Among Ichthyophonus spp. spores from both marine and freshwater fish hosts (Pacific herring, Clupea pallasii, and rainbow trout, Oncorhynchus m...

Abstract
A fragrant, spherical, osmotrophic eukaryote was isolated 27 times from the digestive tracts of marine invertebrates collected from the Northeast Pacific. The isolates were cultured from 7 animal collections over a 2-year period, most from the peanut worm, Phascolosoma agassizii. A small subunit rib...

Abstract
Parasitology (135)2 2008
Abstract
We identify and address the causative agents. Many of the pathogens recently implicated in amphibian mortality and morbidity have been fungal or members of a poorly understood group of fungus-like protists, the mesomycetozoans. One mesomycetozoan, Amphibiocystidium ranae, is known to infect several...

Abstract
Ichthyophonus-like organisms were found in two free-ranging adult spotted salamanders (Ambystoma maculatum) captured within two different vernal ponds in the Virginia Commonwealth University Rice Center for Environmental Life Sciences in Charles City County, Virginia. Histopathologic examination of...

Abstract
We developed an in vitro model to study the cellular and molecular mechanisms of granulomatous inflammation in response to invading pathogens. Ichthyophonus hoferi was used as a target for encapsulation by cultivated leukocytes from the kidney of the rainbow trout (Oncorhynchus mykiss). The encapsul...

Abstract
A protist tentatively designated "Pseudoperkinsus tapetis" belonging to the eukaryotic group Ichthyosporea (Mesomycetozoa) was previously isolated from carpet shell clams in Galicia (northwest Spain). In the present study, based on molecular data, a potential P. tapetis specimen was identified from...

Abstract
We surveyed the diversity of eukaryotic rDNA in raw sediment samples and in two enrichment cultures. More than half of all clones recovered from the raw sediment samples were of the basidiomycetous fungus Cryptococcus curvatus. Among other clones, phylotypes of eukaryotic parasites, such as Apicompl...

Journal of Parasitology (92)6 2006
Abstract
We measured Ichthyophonus sp. prevalence and a series of factors that could contribute to transmission in 16 newt populations during spring 2004. In contrast to our initial hypotheses of trophic transmission, several lines of evidence suggested a role for the amphibian leech (Placobdella picta) in I...

Abstract
Inference of evolutionary relationships between nematodes is severely hampered by their conserved morphology, the high frequency of homoplasy, and the scarcity of phylum-wide molecular data. To study the origin of nematode radiation and to unravel the phylogenetic relationships between distantly rel...

Abstract
Swimming stamina, measured as time-to-fatigue, was reduced by approximately two-thirds in rainbow trout experimentally infected with Ichthyophonus. Intensity of Ichthyophonus infection was most severe in cardiac muscle but multiple organs were infected to a lesser extent. The mean heart weight of in...

Abstract
Two genetically distinct populations of chinook salmon, Oncorhynchus tshawytscha (Walbaum), were simultaneously sampled at the confluence of the Yukon and Tanana rivers in 2003. Upper Yukon-Canadian fish had significantly higher infection prevalence as well as more severe infections (higher parasite...

Abstract
We developed and evaluated a polymerase chain reaction (PCR) test for I. hoferi using primers specific to the parasite's small subunit rDNA. The test has a minimum detection limit of approximately 10(-5) parasite spores per reaction and does not cross-react with the closely related salmon parasites...

Abstract
We determined 1,600 base pairs of DNA sequence in the 18S small ribosomal subunit from two geographically distinct isolates of Dermosporidium penneri. Maximum likelihood and parsimony analysis of these sequences place D. penneri in the order Dermocystida of the class Mesomycetozoea. The 18S rRNA seq...
