Nematode Parasites of Rockfish (Sebastes spp.) and Cod (Gadus spp.) from Waters near Kodiak Island Alaska, USA

Diversity, 2021
Distribution and abundance of common parasitic nematodes in marine fishes is not well documented in many geographic regions. Understanding the influence of large-scale environmental changes on infection rates of fish by nematodes requires quantitative ...

Ocean acidification has a strong effect on communities living on plastic in mesocosms

Limnology and Oceanography Letters, Volume 8, Issue 4, Page 675-684, August 2023., 2023
Abstract We conducted a mesocosm experiment to examine how ocean acidification (OA) affects communities of prokaryotes and eukaryotes growing on single‐use drinking bottles in subtropical eutrophic waters of the East China Sea. Based on 16S rDNA gene sequencing, simulated high CO2 significantly altered the prokaryotic community, with the relative ...

Gnathostoma spinigerum Mitochondrial Genome Sequence: a Novel Gene Arrangement and its Phylogenetic Position within the Class Chromadorea [PDF]

Scientific Reports, 2015
AbstractHuman gnathostomiasis is an emerging food-borne parasitic disease caused by nematodes in the genus Gnathostoma. In spite of their significance as pathogens, these parasites remain poorly understood at the molecular level. In the present study, we sequenced the mitochondrial (mt) genome of G. spinigerum, which infects a range of definitive hosts
