The development of Haemonchus contortus, a nematode parasite of the ovine abomasum, in the laboratory rabbit.

abstract：:The gastrointestinal nematode Heligmosomoides polygyrus bakeri shows enhanced survival in mice with colitis. As the antibody response plays an important role in antiparasitic immunity, antibodies against male and female L4 H. polygyrus were examined in mice with and without colitis.
