G. aExperimental infections of lambs with Trichostrongylus axei; investigations using abomasal cannulae. c1969 aAbstract : Various physiological measurements were made on 3 iambs into which abomasal cannulae had been inserted. One lamb which received 150, 000 Trichostrongylus axei larvae showed signs of acute disease and carried 96, 600 worms at autopsy. From the 14th day of infection abomasal pH rose steadily and function was upset from the 21st day when pH increased to above 6.0. Accompanying this there was an increase in the sodium content of the abomasal fluid and decrease in both potassium content and dry matter. These changes were accompanied by a moderate diarrhoea, a rapid loss in body-weight, a marked terminal haemoconcentration and a decrease in serum albumin levels. The pepsin concentration of the abomasal fluid increased between the 3rd and 4th week and then decreased, whilst the serum pepsinogen level increased during the 4th week and stayed high. In the other 2 lambs chronic infections were set up and similar changes occurred but in general the degree of change was less.
