Introduction: spp. are a public health concern, yet there is still no effective vaccine or medicine available.
Methods: Here, we developed a -specific antibody and found that it targeted a menaquinol cytochrome reductase complex QcrC.
Background: and Shiga toxin (Stx)-producing (STEC) are common causes of food poisoning. We previously demonstrated the efficacy of Stx2B-C-CPE, a fusion protein of the C-terminal region of enterotoxin (C-CPE) and Shiga toxin 2 B subunit (Stx2B), as a bivalent vaccine against and STEC infections.
Methods: Here, we applied an expression system and Triton X-114 phase separation to prepare tag- and endotoxin-free Stx2B-C-CPE for use in vaccine formulations.
