A conserved metalloprotease mediates ecdysis in Caenorhabditis elegans [PDF]

, 2004
Molting is required for progression between larval stages in the life cycle of nematodes. We have identified four mutant alleles of a <i>Caenorhabditis elegans</i> metalloprotease gene, <i>nas-37</i>, that cause incomplete ...

Genomic introgression mapping of field-derived multiple-anthelmintic resistance in Teladorsagia circumcincta [PDF]

, 2017
Preventive chemotherapy has long been practiced against nematode parasites of livestock, leading to widespread drug resistance, and is increasingly being adopted for eradication of human parasitic nematodes even though it is similarly likely to lead to ...

Annotation of two large contiguous regions from the Haemonchus contortus genome using RNA-seq and comparative analysis with Caenorhabditis elegans [PDF]

, 2011
The genomes of numerous parasitic nematodes are currently being sequenced, but their complexity and size, together with high levels of intra-specific sequence variation and a lack of reference genomes, makes their assembly and annotation a challenging ...

Use of Diatomaceous Earth and Copper Oxide Wire Particles to Control Gastrointestinal Nematodes in Lambs [PDF]

, 2020
Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control ...

Effects of condensed tannins on goats experimentally infected with Haemonchus contortus. [PDF]

, 2003
Although the use of tanniferous plants or condensed tannins as an alternative to anthelmintics to control gastrointestinal nematodes has been largely documented in sheep, studies remain scarce in goats.
