Hookworm genomics: dusk or dawn?

Hookworms are parasites, closely related to the model nematode Caenorhabditis elegans, that are a major economic and health burden worldwide. Primarily three hookworm species (Necator americanus, Ancylostoma duodenale, and Ancylostoma ceylanicum) infect humans. Another 100 hookworm species from 19 genera infect primates, ruminants, and carnivores.

First insight into strongylid nematode diversity and anthelmintic treatment effectiveness in beef cattle in the Czech Republic explored by HTS metagenomics.

Parasitic diseases and mitigation of their effects play an important role in the health management of grazing livestock worldwide, with gastrointestinal strongylid nematodes being of prominent importance. These helminths typically occur in complex communities, often composed of species from numerous strongylid genera. Detecting the full diversity of strongylid species in non-invasively collected faecal samples is nearly impossible using conventional methods.

ORFans in Mitochondrial Genomes of Marine Polychaete Polydora.

Most characterized metazoan mitochondrial genomes are compact and encode a small set of proteins that are essential for oxidative phosphorylation, as well as rRNA and tRNA for their expression. However, in rare cases, invertebrate taxa have additional open reading frames (ORFs) in their mtDNA sequences. Here, we sequenced and analyzed the mitochondrial genome of a polychaete worm, Polydora cf.
