Figure 8. Passive immunization (anti-rAce Ig versus PI Ig) in rat endocarditis model.

Figure 8

In the panel on the left, empty circles and empty triangles represent OG1RF inocula for pre-immune (PI) Ig treated and affinity purified specific anti-rAce Ig treated rats, respectively. In the panel on the right, solid circles and solid triangles represent OG1RF recovered from rat vegetations 24 h post infection. Horizontal bars represent the geometric means. Significantly fewer rats were infected by OG1RF in rAce Ig (2 mg/kg) (2/10) versus PI Ig (2 mg/kg) (5/6) treated rats (P = 0.0001 by Fisher's exact test). Rats (PI Ig treated) showed a mean ± SD increase of 3.8±1.4 log10 OG1RF CFU/gm from vegetations versus anti-rAce Ig treated rats (P = 0.0146 by unpaired t test).
