Ascaridomorph nematodes threaten the health of humans and other animals worldwide. Despite their medical, veterinary and economic importance, the identification of species lineages and establishing their phylogenetic relationships have proved difficult in some cases. Many working hypotheses regarding the phylogeny of ascaridomorphs have been based on single-locus data, most typically nuclear ri...

Three new diterpene esters with a myrsinol-type skeleton have been isolated from Euphorbia decipiens BOISS. & BUHSE. The structure elucidation of the isolated compounds was based primarily on two-dimensional (2D)-NMR techniques including correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC), heteronuclear multiple bond correlation (HMBC) and nuclear Overhauser effect ...

Distribution and abundance of common parasitic nematodes in marine fishes is not well documented many geographic regions. Understanding the influence large-scale environmental changes on infection rates fish by requires quantitative assessments parasite for multiple host species. We collected samples two species cod eight rockfish (total 232 specimens) from waters near Kodiak Island, Alaska, US...

A new species of genus Flaviata Lu & Qin, Flaviata longa sp. nov. is described from Yunnan (southwest China). An identification key for males of all known species in this genus is provided. Photographs and illustrations of adults and male genitalia of the new species are also given. New synonymies for two species in the leafhopper subgenus Empoasca (Matsumurasca) Anufriev of Empoascini are prop...

BACKGROUND Anisakis and Pseudoterranova are the main genera involved in human infections caused by nematodes of the Anisakidae family. Species identification is complicated due to the lack of differential morphological characteristics at the larval stage, thus requiring molecular differentiation. Pseudoterranova larvae ingested through raw fish are spontaneously eliminated in most cases, but me...
