Exceptional endemicity of Aotearoa New Zealand biota shows how taxa dispersal traits, but not phylogeny, correlate with global species richness

open access: yesJournal of the Royal Society of New Zealand, Volume 54, Issue 1, Page 144-159, February 2024.
ABSTRACT Species’ with more limited dispersal and consequently less gene flow are more likely to form new spatially segregated species and thus contribute disproportionally to endemic biota and global species richness. Aotearoa New Zealand has exceptional endemicity, with 52% of its 54,000 named species endemic, including 32%, 39% and 68% for ...

Large‐scale eDNA monitoring of multiple aquatic pathogens as a tool to provide risk maps for wildlife diseases

open access: yesEnvironmental DNA, Volume 6, Issue 1, January–February 2024.
Environmental DNA techniques can be applied for the simultaneous detection of multiple aquatic wildlife pathogen species. In this study we conducted an eDNA‐based survey monitoring several pathogens of concern in Switzerland. We identify advantages and limitations of eDNA‐based pathogen monitoring versus more conventional methods.

Monogenean Sparicotyle chrysophrii: The major pathogen of the Mediterranean gilthead seabream aquaculture

open access: yesReviews in Aquaculture, Volume 16, Issue 1, Page 287-308, January 2024.
Sparicotylosis has been present in Mediterranean aquaculture of the gilthead seabream for the past 25 years, yet disease management and treatments are not effective. This is further jeopardised by global warming and resistance of Sparicotyle chrysophrii to available anthelminthic compounds.

Molecular data implicate bryozoans as hosts for PKX (Phylum Myxozoa) and identify a clade of bryozoan parasites within the Myxozoa

open access: yesParasitology, 1999
Proliferative kidney disease (PKD), a condition associated with high mortality in salmonid fish, represents an abnormal immune response to the presence of an enigmatic myxozoan, which has been designated simply as PKX organism because its generic and specific status are obscure. Phylogenetic analyses of partial sequences of the 18S rDNA of PKX and of

New Japanese Record of Henneguya postexilis (Cnidaria: Myxobolidae) from Gills of Alien Channel Catfish Ictalurus punctatus (Siluriformes: Ictaluridae) in Japan

open access: yesSpecies Diversity
Henneguya postexilis Minchew, 1977 (Cnidaria: Myxobolidae) is described as a novel record for Japan. It was found in the gills of non-native Ictalurus punctatus (Rafinesque, 1818) (Siluriformes: Ictaluridae), which were collected from the Omoi River, a ...

Ultrastructural localisation of carbohydrates in four myxosporean parasites

open access: yesParasite, 2000
The existence and localisation of carbohydrates in four myxosporean parasites was investigated at transmission electron microscope, using lectin histochemistry techniques. The Myxosporea studied showed different lectin binding patterns.

Dietary vegetable oils do not alter the intestine transcriptome of gilthead sea bream (Sparus aurata), but modulate the transcriptomic response to infection with Enteromyxum leei

open access: yesBMC Genomics, 2012
Background Studies conducted with gilthead sea bream (Sparus aurata L.) have determined the maximum dietary replacement of fish meal and oil without compromising growth or product quality.

Effect of oral administration of Kudoa septempunctata genotype ST3 in adult BALB/c mice

open access: yesParasite, 2015
Kudoa septempunctata (Myxozoa: Multivalvulida) infects the muscles of olive flounder (Paralichthys olivaceus, Paralichthyidae) in the form of spores. To investigate the effect of K. septempunctata spores in mammals, adult BALB/c mice were fed with spores
