Gastrointestinal pathogenic loads following murine fecal microbiota transplantation of C. jejuni infected secondary abiotic mice. Secondary abiotic mice were infected with C. jejuni on days 0 and 1 by gavage. Starting a week later, infected mice were subjected to peroral fecal microbiota transplantation (FMT) from murine donors (open circles) on three consecutive days or received vehicle (mock; closed circles). On day 21 post-infection (i.e., 14 days post FMT), C. jejuni loads were determined in luminal samples taken from stomach, duodenum, ileum, and colon by culture and expressed as colony forming units per gram (CFU/g). Medians, numbers of pathogen-positive mice out of the total number of analyzed animals (in parentheses) and significance levels (p-values) determined by the Mann-Whitney U test are given. Data were pooled from three independent experiments.
