From: Local immunization impacts the response of dairy cows to Escherichia coli mastitis

Experimental scheme. Three groups of six cows were immunized before calving by using three different immunization schedules. About two months after calving, all cows were challenged by inoculation of E. coli strain P4 into one quarter. Milk and blood samplings were carried out at the indicated times post-inoculation to monitor the infection and the immune response.
