Abstract

One-day-old turkeys were inoculated per os with material shown previously to induce stunting syndrome (SS). Weight gain and feed efficiency of inoculated poults from 1 to 13 days of age were impaired (P less than 0.01) compared with uninoculated poults. Examination of the jejunal mucosa by scanning and transmission electron microscopy showed the presence of long-segmented filamentous organisms (LSFOs) in poults that had been inoculated with SS. These organisms were not seen in jejuna of uninoculated poults. Further research is needed to characterize LSFOs and to determine their involvement, if any, in the adverse effects associated with SS.
