Comparative Transcriptome Analysis of Shiga Toxin-Producing Escherichia coli O157:H7 on Bovine Rectoanal Junction Cells and Human Colonic Epithelial Cells during Initial Adherence.

ABSTRACT: Shiga toxin-producing Escherichia coli (STEC) are notorious foodborne pathogens, capable of causing severe diarrhea and life-threatening complications in humans. Cattle, acting as both primary reservoirs and asymptomatic carriers of STEC, predominantly harbor the pathogen in their rectoanal junction (RAJ), facilitating its transmission to humans through contaminated food sources. Despite the central role of cattle in STEC transmission, the molecular mechanisms governing STEC's adaptation in the RAJ of the asymptomatic reservoir host and its subsequent infection of human colonic epithelial cells, resulting in diarrhea, remain largely unexplored. This study aims to uncover these complicated dynamics by focusing on the STEC O157:H7 serotype within two distinct host environments, bovine
