a
Samples were collected on different days postinfection from each group. Group 4 (Ech_0660-infected animals) contained zero positives, Ech_0379-infected animals (group 3) had a few positives (19%), and the wild-type-infected group had 59% positives. The Ech_0284 mutant-infected group had 61% blood positives, similar to the wild-type-infected group.
b
The minus and plus signs refer to samples tested negative or positive by culture recovery and/or nested PCR, respectively.
