  • a Map positions are indicated in centisomes (23, 63). pSLT is the S. typhimuriumvirulence plasmid (85).

  • b Determined by the method described in references 24 and 25.

  • c LD50s were determined for intragastrically infected mice; fold attenuation refers to the ratio of the LD50 of the respective mutant strain to the LD50 of wild-type S. typhimurium. Experiments were done previously (24, 158, 240).

  • d ND, not determined.
