Abstract : Jarett et al. working with an immune globulin preparation derived from hyper-immune serum, have successfully immunized five lo-week-old calves against Dictyocaulus viviparus infection. A difference between the immunized and control calves, both infected with 4, 000 D. moiparus larvae, became apparent on the 17th day after infection when the respiratory rate of the controls was considerably higher than that of the immunized calves. On the 25th and 29th days after infection faecal larval counts showed 50-500 and 100-900 larvae per gramme respectively in the control calves and none or very few in the immunized group. The average numbers of lungworms collected post mortem were 786 in the controls and 37.4 in the immunized calves. Complement fixation tests revealed the presence of circulating antibodies in both groups although the level in the control groups never increased to the equivalent of the minimum level reached in the immunized groups. There was no evidence that a cellular response enhancing the pneumonic effect took place in the lungs of immunized animals. s.w. |
