Survival of mice infected with YPIII or the ifp- and invC-deficient mutants. Cells (2 × 109) of Y. pseudotuberculosis wild-type strain YPIII or the ifp (YP97) and invC (YP98) mutant strains were orally introduced into 7-week-old BALB/c mice. The survival of BALB/c mice was monitored for up to 14 days. Data were analyzed by the log-rank (Mantel-Cox) test. Asterisks indicate results that differed significantly from those for YPIII (P < 0.05).
