Stimulated pepsinogen secretion from dispersed abomasal glands exposed to Ostertagia species secretion
Eckersall, P. D.
Carbachol and secretions from Ostertagia species parasites significantly (P less than 0.001) stimulated isolated preparations of dispersed gastric glands from bovine and ovine abomasal mucosa to secrete pepsinogen. Atropine reduced the response to both secretagogues. Live adult and larval stages of Ostertagia ostertagi and O circumcincta and homogenates of these parasites did not significantly (P greater than 0.05) increase pepsinogen production from bovine or ovine gland preparations.
