[Electromyographic analysis of motor perturbations linked with gastrointestinal strongyloidiasis]

The effects of experimental infection of lambs with third stage Trichostrongylus larvae are described. Preceding diarrhea, disturbances in the motility of the reticulum, abomasum and jejunum were observed by electromyography. Disappearance of the migrating myoelectric complexes occurred about 24 h before diarrhea and was accompanied by a decrease in both the frequency of reticular contractions and of contractions propagated through the antro-duodenal junction. The significance of these findings is discussed and compared with natural infestation in the field.
