One of the most intriguing defence strategies which aquatic organisms developed through evolution is multixenobiotic resistance (MXR). The key mediators of MXR activity are ATP-binding cassette (ABC) transport proteins. They provide resistance of aquatic organisms by binding xenobiotics and extruding them from cells in an energy-dependent manner. Since Cyprinid fish species are common target in...
A recent threat to European fish diversity was attributed to the association between an intracellular parasite, Sphaerothecum destruens, and a healthy freshwater fish carrier, the invasive Pseudorasbora parva originating from China. The pathogen was found to be responsible for the decline and local extinction of the European endangered cyprinid Leucaspius delineatus and high mortalities in stoc...
Stool samples from a total of 1,008 persons were examined for intestinal parasites during a comprehensive study on the epidemiology of small fluke infections in Laos. The prevalence of small fluke eggs in the stool was seen to peak at age 20 years, particularly in men from villages (90.4%). Three quarters of infections belong to the category of light infections and only 0.6% to the category of ...
The European Standard EN 14757 recommends gillnet mesh sizes that range from 5 to 55mm (knot-to-knot) for the standard monitoring of fish assemblages and suggests adding gillnets with larger mesh sizes if necessary. Our research showed that the recommended range of mesh sizes did not provide a representative picture of fish sizes for larger species that commonly occur in continental Europe. We ...
Reexamination of the male holotype of the rhabdochonid nematode Rhabdochona leucaspii Kritscher, 1979, originally described from the intestine of the cyprinid fish Leucaspius prosperi [= Ladigesocypris ghigii (Gianferrari)] from Rhodes Island, Greece, confirmed its morphological and biometrical identity with Rhabdochona denudata (Dujardin, 1845), a common and widespread parasite of cyprinids an...
Species from all major jawed vertebrate taxa possess linked polymorphic class I and II genes located in an MHC. The bony fish are exceptional with class I and II genes located on different linkage groups. Zebrafish (Danio rerio), common carp (Cyprinus carpio), and barbus (Barbus intermedius) represent highly divergent cyprinid genera. The genera Danio and Cyprinus diverged 50 million years ago,...
Gut microbiota play key roles in host nutrition and metabolism. However, little is known about the relationship between host genetics, gut microbiota and metabolic profiles. Here, we used high-throughput sequencing and gas chromatography/mass spectrometry approaches to characterize the microbiota composition and the metabolite profiles in the gut of five cyprinid fish species with three differe...
