Transfer and persistence of bovine immunoglobulins in lambs fed a colostrum replacer.

Background: Colostrum-derived antibodies are crucial for the protection of newborn lambs from infectious diseases. Several colostrum replacer products that contain bovine antibodies are on the market. We investigated the absorption and persistence of bovine antibodies from a powdered colostrum replacer in newborn lambs.

Congenital ureteric diverticula in children and adults: classification, radiological and clinical features.

To date, about 100 cases of a blind-ending branch of a bifid ureter have been reported. We present 13 clinically, radiologically and histologically evaluated cases of congenital ureteric diverticulum. We believe this anomaly is not as rare as hitherto believed and suggest the term congenital ureteric diverticulum for a blind-ending branch of a bifid ureter.
