The present study was conducted to detect the differences in glycohistochemical features in the epididymal duct of the dromedary camel and the water buffalo. Epididymal sections (caput, corpus and cauda) from both species were stained with fluorescein isothiocyanate (FITC) conjugated lectins. Binding sites for five lectins (DBA, GSA-1, HPA, PNA and WGA) have been found in both species. The binding sites of different lectins showed significant variations in the pattern of distribution in both a species. This included both species-specific and region-specific order. Additionally, only three (GSA-1, PNA and WGA) out the five lectins studied exhibited binding sites in all epididymal regions in both species. The other two lectins (DBA and HPA) followed the same order recorded for the other three (GSA-1, PNA and WGA) in buffalo, but failed to show any binding sites in cauda epididymis in camel. In conclusion, the variable regional and species-specific distribution features of lectins revealed that both species have diverse glycomic characteristics that may be related to their different reproductive patterns. However, the glycome-associated functional capacities remain obscured and need further profound investigations.
