Understanding the species and their challenges to animal health and livestock species for informed development of new, specific treatment strategies.

species are parasitic organisms of vertebrates with a worldwide distribution. They have an important impact globally upon human and animal health, and livestock productivity. The life cycle of these species is complex and difficult to disrupt to improve human health, animal health, food security and economic growth.

Anatomy and Pathology of the Texel Sheep Larynx.

Laryngeal chondritis, or "Texel throat", is a disease affecting the upper respiratory tract of sheep with breeds like the Texel appearing to be predisposed. Previous work suggests the conformation of these breeds of sheep may be predisposing these animals to laryngeal disease. This study evaluated the anatomy of the Texel sheep larynx and describes incidental pathology.
