Table 1.
Genotype a | Route of Inoculation | Organ b | Median CI c | Number of mice | P value d |
---|---|---|---|---|---|
tatC | oral | small intestine | 0.0065 | 11 | <0.0005 |
oral | spleen | 0.0077 | 16 | <0.0005 | |
i.p. | spleen | 0.0045 | 5 | <0.0005 |
Strains used were JS135 and JS1195 for oral infections, and 14028 and JS1194 for i.p. infections.
The entire small intestine was dissected and homogenized.
The competitive index (CI) was calculated as described in the experimental procedures.
The student’s t test was used to compare the output and the inoculums.
