Comparison with previously reported detection methods for tcdA and confirmation by ELISA for TcdA

Two pairs of classic PCR primers for gene tcdA (Kato et al. 1999; Lemee et al. 2004) were compared with our method using 33 C. difficile RT017 isolates and 30 other types of clinical isolates preserved in our laboratory (Table S3). For inconsistent results, ELISA was employed for clarification. Briefly, negative control (ATCC43593), positive control (ATCC-BBA1803), and tested C. difficile (N20) isolates (Table S3) were anaerobically cultured in BHI liquid medium at 37 °C for 24 h. After centrifugation, the supernatant was taken and filtered through a 0.45 μm filter, then incubated overnight at 4 °C in a 96-well plate. The plate was washed with PBST(Phosphate Buffered Saline + Tween) and blocked with 5% bovine serum albumin at 37 °C for 2 h. Polyclonal antibody (List Biological Laboratories, Toxin A IgY, 1:1000 dilution) was used for the first hybridization, and horseradish peroxidase (HRP-conjugated goat anti-chicken IgY (Invitrogen, 1:5000 dilution) served as the secondary antibody. …

Induction and assessment of EAE

8-week-old male C57BL/6 mice were injected subcutaneously in the dorsal flanks with 3 mg/ml MOG35-55 peptide (300 μg per mouse) in CFA containing 5 mg/ml heat-killed Mycobacterium tuberculosis (500 μg per mouse) on day 0. Mice were injected with Pertussis toxin (150 ng per mouse, list labs) on days 0 and day 2 through the retroorbital vein. In Tivantinib prevention trails, Tivantinib was intraperitoneally injected into mice (10 mg/kg) beginning at day 0 to day 22 every two days. …
