FIG. 8.

Effects of intramammary infection with E. coli or S. aureus on levels of sCD14 and LBP. Concentrations of sCD14 (A) and LBP (B) in milk obtained from quarters infused with either saline, E. coli, or S. aureus, as well as levels of LBP in plasma (C) obtained from these infected cows, were assayed by ELISA. Mean (± standard error) concentrations of both proteins are shown. * and #, significantly increased in milk (A and B) or plasma (C) obtained from E. coli- or S. aureus-infected cows, respectively, relative to time zero (P < 0.05).
