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 ...

Alternative Approaches and Plant‐Based Remedies for Livestock Health Management Among the Batswana of Southern Africa: A Review

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT Due to limited access to, and the high cost of conventional veterinary services, Batswana communities often rely on ethnoveterinary practices for livestock health management. This review provides an in‐depth analysis on the ethnoveterinary uses, biological properties and safety assessment of plants utilised in livestock husbandry. A systematic

Evolution of Ivermectin Resistance in the Nematode Model Caenorhabditis elegans: Critical Influence of Population Size and Altered Emodepside Efficacy

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT The emergence and spread of anthelmintic resistance represent a major challenge for treating parasitic nematodes, threatening mass‐drug administration control programs in humans and zoonotic hosts. Currently, experimental evidence to understand the influence of management (e.g., treatment dose and frequency) and parasite‐associated factors (e ...

Why is it important to correctly identify Haemonchus species? Por que é importante a identificação correta das espécies de Haemonchus?

Revista Brasileira de Parasitologia Veterinária, 2011
Parasitic gastroenteritis caused by Haemonchus spp. is a major cause of economic losses in the livestock industry because it impairs weight gain and increases mortality in cattle and small ruminants, especially in tropical and subtropical areas.

Large‐scale reproductive loss in sheep due to Border disease virus infection, New South Wales, Australia

Australian Veterinary Journal, Volume 104, Issue 3, Page 137-149, March 2026.
Border disease viruses (BDV) and bovine viral diarrhoea viruses (BVDV) are members of the Pestivirus genus in the family Flaviviridae. While BVDV is one of the most significant endemic viral infections of cattle in Australia, BDV infection is generally considered to be uncommon in Australian sheep.
