Effect of Dictyocaulus filaria infection on the osmotic fragility of sheep erythrocytes.
The osmotic fragility of erythrocytes in lambs experimentally infected with Dictyocaulus filaria was studied weekly for 71 weeks. In acute infection, the erythrocytic fragility increased from the third week of infection onwards, reached its peak by the eleventh week and declined thereafter. However, in the chronic immune-carrier stage, this increase in the fragility did not return to normal until the end of the experiment. This enhanced fragility showed a positive correlation with the faecal larval count, worm burden and the extent of lung damage in lambs.
