− | ===Introduction===
| |
− | Haemonchus contortus is a nematode parasite from the family '''Trichostrongyloidea.''' It is found worldwide, and is an extremely important parasite of sheep and goats, particularly in tropical/ subtropical regions.
| |
− | | |
− | Within the UK, it is found most commonly in the South, where the climate tends to be a little warmer and drier. Some have shown complete resistance to current anthelemintics which is posing a real problem, making sheep and goat farming extremely difficult in some areas of the country.
