FIG 7.
Rabbit antibodies to CP5-CRM or CP8-CRM reduce bacteremia induced by S. aureus Reynolds (CP5). Mice were passively immunized with 0.5 ml of preimmune serum or serum raised to CP5-CRM or CP8-CRM 24 h before challenge with 1 × 107 CFU S. aureus Reynolds (CP5). The data represent the results of quantitative blood cultures on individual animals, and the horizontal lines and numbers represent median numbers of CFU/ml blood for each group (n = 15). Bacteremia levels from mice given immune serum were compared by the Mann-Whitney test to those from mice given preimmune serum.
