Ten multiparous Holstein cows were used to determine the effects of negative energy balance (NEB) on the immune response to a Streptococcus uberis (strain O140J) mastitis challenge during midlactation. Before the study, milk from all quarters of each cow was bacteriologically negative, with a composite somatic cell count of
