Wild type SPE Ac 11/119/11
  • a Animals were intravenously administered 5 μg of wild-type or mutant SPE A per kg. Four hours later, the rabbits were given 10 μg of S. enterica serovar Typhimurium endotoxin intravenously. Animals were monitored for 48 h for lethality.

  • b Miniosmotic pumps contained 500 μg of wild-type or mutant SPE A.

  • c Cumulated total control rabbits.
