| Abstract: | The infective stage of the cattle lungworm, Dictyocaulus viviparus, was able to migrate in agar gel when activated by bile. The number of larvae which penetrated the upper surface of a 2 mm thick agar layer was counted and found to be independent from the agar concentration. Larvae which had migrated out of the agar remained on the surface and did not re-enter. The agar migration process was temperature dependent. Influence of time as well as dependency of agar thickness was investigated. The significance of these findings is discussed. |
