*BLASTN available from http://blast.ncbi.nlm.nih.gov. Expect-value cutoff 10–40.
†Diarrheic fecal sample collected while patient was ill. Total sequences 96,941; total (100%) BLAST matches 11,777.
‡Nondiarrheic fecal sample collected 3 mo after patient had recovered. Total sequences 106,327; total (100%) BLAST matches 8,397.
