    1. Dermocystid infection and associated skin lesions in free-living palmate newts (Lissotriton helveticus) from Southern France
      Milagros González-Hernández, Mathieu Denoël, ... Karina Acevedo-Whitehouse

      Parasitol Int 59(3):7 (2010) PMID 20450984

      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...
    2. Prior residency does not always pay off--co-infections in Daphnia.
      Jennifer N Lohr, Mingbo Yin, and Justyna Wolinska

      Parasitology 137(10):1493-500 (2010) PMID 20444300

      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...
    3. Microscopic eukaryotes living in a dying lake (Lake Koronia, Greece).
      Savvas Genitsaris, Konstantinos Ar Kormas, and Maria Moustaka-Gouni

      FEMS Microbiol Ecol 69(1):75-83 (2009) PMID 19453739

      The morphological and phylogenetic diversity of the microscopic eukaryotes of the Lake Koronia water column was investigated during a mass kill of birds and fish in August-September 2004. The dominant morphospecies corresponded to the known toxin-producing species Prymnesium parvum,...
    4. Transmission of the parasite Ichthyophonus hoferi in cultured rainbow trout and comparison of epidemic models.
      Masashi M Yokota, Seiichi S Watanabe, ... Takahiko T Usui

      J Aquat Anim Health 20(4):207-14 (2008) PMID 19306610

      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....
    5. Inactivation of Ichthyophonus spores using sodium hypochlorite and polyvinyl pyrrolidone iodine.
      P K PK Hershberger, C A CA Pacheco, and J L JL Gregg

      J Fish Dis 31(11):853-8 (2008) PMID 19238746

      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...
    6. Differential survival of Ichthyophonus isolates indicates parasite adaptation to its host environment.
      P K PK Hershberger, C A CA Pacheco, ... S E SE LaPatra

      Parasitol Res 94(5):1055-9 (2008) PMID 18576846

      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...
    7. Multiple Isolations of a Culturable, Motile Ichthyosporean (Mesomycetozoa, Opisthokonta), Creolimax fragrantissima n. gen., n. sp., from Mar...
      Wyth L WL Marshall, Gail G Celio, ... Mary L ML Berbee

      Protist 159(3):19 (2008) PMID 18539526

      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...
    8. Potential for cross-contamination of in vitro explant cultures initiated from Ichthyophonus-infected rainbow trout, Oncorhynchus mykiss (Wal...
      S S LaPatra, R R Kocan, and P P Hershberger

      J Fish Dis 31(4):317-20 (2008) PMID 18353024

    9. Widespread infection of the Eastern red-spotted newt (Notophthalmus viridescens) by a new species of Amphibiocystidium, a genus of fungus-li...
      T R Raffel, T Bommarito, ... L A Shackelton

      Parasitology 135(2):203-15 (2008) PMID 17931460

      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...
    10. In vitro leukocyte-encapsulation model in rainbow trout (Oncorhynchus mykiss)
      Osamu O Kurata, Madoka M Nakabayashi, and Kishio K Hatai

      Dev Comp Immunol 32(6):9 (2008) PMID 18093653

      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...
