FIG. 3.

Wild-type V. cholerae O395 (classical biotype) recovery from segments of the small bowel of a suckling mouse. The mouse was intragastrically inoculated with 3 × 10⁶ CFU, and CFU were recovered from 1-cm segments proceeding from the pylorus (x-axis origin) toward the cecum 10 h after infection. The numbers of CFU recovered from three of the segments are shown above their bars in parentheses.
