  • a Thirty-nine pAA+ strains were isolated from children with diarrhea, 5 pAA+ strains were isolated from controls, and 19 pAA+ strains were isolated from adults with diarrhea.

  • b P < 0.05 for difference between strains from children and adults with diarrhea.

  • c P < 0.005 for difference between strains from children and adults with diarrhea.

  • d P < 0.025 for difference between strains from children with and without diarrhea.
