Abstract

Highlights: Bovine intestinal epithelial cells (BIECs) were characterized for lectin binding. Immortalized BIECs showed changes in the binding profiles of many lectins. Salmonella Dublin and S. Mbandaka showed strong invasion in BIEC-c4 cells. BIEC-c4 cells were permissive to bovine rotavirus but lacked virus replication. LPS stimulation of BIECs upregulated IL-6, IL-8, and IL-10 gene expression. Abstract: In this study, primary and immortalized bovine intestinal epithelial cells (BIECs) were characterized for the expression of surface carbohydrate moieties. Primary BIEC-c4 cells showed staining greater than 90 % for 16 lectins but less than 50 % staining for four lectins. Immortalized BIECs showed significantly different lectin binding profile for few lectins compared to BIEC-c4 cells. BIEC-c4 cells were studied for infectivity to E. coli, Salmonella enterica, bovine rotavirus, bovine coronavirus, and bovine viral diarrhea virus. Bovine strain E. coli B41 adhered to BIEC-c4 cells and Salmonella strains S. Dublin and S. Mbandaka showed strong cell invasion. BIEC-c4 cells were susceptible to bovine rotavirus. LPS stimulation upregulated IL-10, IL-8, and IL-6 expression and Poly I:C upregulated TLR 8 and TLR 9 expression. This study provides important knowledge on the glycoconjugate expression profile of primary and immortalized BIECs and infectivity and immune responses of primary BIECs to bacterial and viral pathogens or ligands.
