Development of a vaccine against haemonchus contortus.
Haemonchus contortus is an economically important nematode parasite of sheep and the occurrence worldwide of strains resistant to anthelmintic chemicals has emphasized the need to develop a vaccine against it. Here, Ed Munn describes the approach to this problem adopted in his laboratory. The principle developed should be applicable to other gastrointestinal parasites.
