The influence of protein supplementation on the immune response to Haemonchus contortus.
S. Strain,Michael J. Stear +1 more
TL;DR: A major protective mechanism in lambs against the abomasal parasite Ostertagia (Teladorsagia) circumcincta appears to be the immunoglubulin (Ig)A‐mediated suppression of worm growth and fecundity, and it is indicated that IgA may play a similar role in the control of another abomaal parasite Haemonchus contortus.

How lambs control infection with Ostertagia circumcincta.
TL;DR: The IgA mediated suppression of worm growth and fecundity appears to be the major mechanism of resistance to O. circumcincta in lambs.

The relationship between IgA activity against 4th-stage larvae and density-dependent effects on the number of 4th-stage larvae of Teladorsagia circumcincta in naturally infected sheep
TL;DR: There was a statistical interaction between the number of adults and IgA activity that moderated their combined effect and indicated that the distribution of 4th-stage larvae was more overdispersed at low levels of infection.

The recognition of molecules from fourth-stage larvae of Ostertagia circumcincta by IgA from infected sheep.
S. Strain,Michael J. Stear +1 more
TL;DR: Results indicate that the parasite‐specific IgA response, or something extremely closely associated with it, is the major immunological mechanism controlling worm length.

The relationship between the number and size of nematodes in the abomasum and the concentration of pepsinogen in ovine plasma
TL;DR: Six-month-old lambs that had been naturally infected with predominantly Teladorsagia (Ostertagia) circumcincta were tested for plasma pepsinogen concentrations and results imply that variation among lambs in the pathogenic effects of T. circuma depends upon the mean size of the worms as well as the number of worms present.
