A.  aCorrelations between numbers of enteric nematode parasites in grazing lambs.h[electronic resource]  c1984  aAbstract: An examination was made of correlations between counts of the enteric nematodes Haemonchus, Ostertagia, Trichostrongylus and Nematodirus from 104 lambs killed over a 3-week period in 1 year. Logarithmically transformed numbers of all genera were positively correlated, which supports the hypothesis that host-mediated common factors influence numbers of all these genera. It was found that the correlations between genera parasitising the same gastrointestinal organ were significantly stronger than the correlations between genera parasitising different gastrointestinal organs, suggesting the existence of regulatory common factors that are organ-mediated. Self-cure and cross-protection may be examples of such organ-mediated factors.  aAnimal parasitic nematodes  aNematoda  aOstertagia  aParasitology  aSheep  aTrichostrongylus  aHaemonchus Contortus  aOvino  aParasitologia  aNematodeo gastrintestinal  tInternation Journal for Parasitologygv.14, n.6, p.587-589, 1984.
