===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.
