Abstract
The present study was undertaken to establish the long-term effect of a single dose of carbendazim in
the tubular region of the infundibulum of Japanese quail using scanning (SEM) and transmission (TEM)
electron microscopy. At a dose of 400mg/kg bodyweight, carbendazim in sunflower oil base was
administered orally to mature Japanese quails. The control group received the oil base only. The effects
of carbendazim on ultrastructural features of infundibulum were examined in spatial temporal periods
post-exposure. At SEM level, loos of cilia were observed from 5 days post-exposure. At TEM level,
pyknosis, karyorrhexis, swollen mitochondria, dilated RER cisternae, increased number of lysosomes and
vacuoles were observed from 24 hours post-exposure. Compound cilia and loos of striated rootlets were
also observed. Thickening and duplication of the basal lamina were identified from 12 days post-
exposure. These results suggest oviductal regression due to carbendazim toxicity and signs of epithelial
recovery at later stages post-exposure.
