Studies on the Serological Response in Sheep to Naturally Acquired Gastro-intestinal Nematodes: II. Responses in a Low Ground Flock

  • E. J. L. Soulsby (a1)
Extract

An inverse relationship has been demonstrated between egg counts and antibody titres. This relationship is also evident on a seasonal basis in the “spring rise”.

The “spring rise” is preceded by a decrease in the immune status of the sheep and is terminated by a self cure mechanism which establishes a period of protection.

The significance of these findings is discussed with regard to the onset and development of the “spring rise”.
