Infection with Clostridioides difficile significantly reduced incidence of collagen-induced arthritis in DBA/1J × B10.Q mice. (A) Macroscopic pictures of healthy (upper row) and arthritic paws (middle row) and corresponding scoring schemes (lower row) are shown. Middle row from left to right: an arthritis score of 1 (one inflamed digit), 15 (five inflamed digits, inflamed tarsal and metatarsal joints), 1 (one inflamed digit), and 11 (one inflamed digit, inflamed tarsal and metatarsal joints) respectively. (B) inverted Kaplan-Meier plot shows incidences of collagen-induced arthritis after mice were boosted on experimental day 49. Asterisks denote an extremely significant difference between the groups at the various time points as calculated via log rank (Mantel-Cox) test. The resulting p-value was 0.000363.
