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 influence of age on the variation among sheep in susceptibility to natural nematode infection
TL;DR: A longitudinal study of faecal nematode egg counts was made in naturally infected Scottish Blackface sheep over two grazing seasons to 75 weeks of age, finding lambs with relatively low faecic egg counts after 3 months of age are likely to retain their advantage in the following year.

The influence of relative resistance and urea-supplementation on deliberate infection with Teladorsagia circumcincta during winter.

TL;DR: A combination of relatively resistant sheep and nutritional supplementation appears most efficient at controlling infection with Teladorsagia circumcincta.

Fructosamine concentration and resistance to natural, predominantly Teladorsagia circumcincta infection
Michael J. Stear,Peter David Eckersall,Peter A. Graham,Quintin McKellar,S. Mitchell,Stephen Bishop +5 more
TL;DR: Fructosamine concentrations are potentially useful indicators of the severity of nematode infection and may predict magnitude of subsequent infection in naturally infected lambs.

The genetic control of IgA activity against Teladorsagia circumcincta and its association with parasite resistance in naturally infected sheep
S. Strain,Stephen Bishop,Neil Henderson,A. Kerr,Quintin McKellar,S. Mitchell,Michael J. Stear +6 more
TL;DR: Under conditions of natural parasite challenge, plasma IgA activity may help to identify lambs resistant to T. circumcincta with shorter adult nematodes.
