Prevention of alterations in the transport of nutrients in pyelonephritic rats by immunization with pili.
The uptake of D-glucose, L-aspartate, L-lysine and L-proline was studied in renal brush border membrane vesicles prepared from control, infected and actively immunized-infected rats. The uptake of D-glucose, L-lysine and L-proline was decreased significantly (p less than 0.05) during the course of infection in the infected animals. However, the uptake of L-aspartate was increased significantly (p less than 0.05) in early stages and decreased significantly (p less than 0.05) in later stages of infection in the infected animals. When the animals were actively immunized with pili, still there were changes in the uptake of D-glucose and L-aspartate, but the changes appeared later and less pronounced. No change in the uptake of L-lysine and L-proline was observed in the immunized-infected animals. The findings demonstrated that active immunization with pili prevents alterations in the uptake of nutrients in pyelonephritic rats.
