Effect of SAP deficiency on the survival of C57BL/6 mice during
bacterial infection. (a) E. coli O111:B4,
108 organisms injected i.v. (b) E.
coli J5, 109 organisms injected i.v. Each result
shown in a and b is typical of at least
two identical experiments with each organism. (c)
E. coli J5, 109 organisms injected i.v. at
time 0; isolated human SAP, 10 mg per mouse, was injected i.p. at −2 h
and 16 h. P values (log rank test) represent
significant differences in survival between SAP−/− and
SAP+/+ or SAP-reconstituted SAP−/− mice.
