Figure 3. Lactobacillus rhamnosus consumption shaped the composition of intestinal microbiota during F4⁺ETEC infection.

(A) Coliforms, (B) Lactobacilli, (C) Bifidobateria, (D) Enterococci and (E) Bacteroides. The contents from the stomach, mid-jejunum, distal ileum, caecum and mid-colon were collected at day 15 after weaning (1 week after F4⁺ETEC challenge) for microbial cultures. Results are presented as log₁₀ CFU/g contents, and all counts were performed in triplicate. Data are presented as means ± SEM (n = 5 per group). *P<0.05; **P<0.01.
