Effects of engineered Bacillus subtilis on diarrhea incidence of weaned piglets at 15 d after challenge with enteropathogenic Escherichia coli

Phase	Diarrhea incidence¹⁾ (%)

	Untreated control	Wild-type Bacillus subtilis	Engineered Bacillus subtilis	Chlortetracycline
Day 1–15	31.7^c	26.1^b	20^a	18.3^a
Day 16–30	38.9^c	33.3^b	28.3^a	27.2^a

¹⁾

Diarrhea incidence = Days of diarrhea piglets/12 (pigs)×15 d.
