WebDec 9, 2024 · Symptoms of cholera infection can include: Diarrhea. Cholera-related diarrhea comes on suddenly and can quickly cause dangerous fluid loss — as much as a quart (about 1 liter) an hour. Diarrhea due to cholera often has a pale, milky appearance that resembles water in which rice has been rinsed. Nausea and vomiting. WebCholera toxin A-subunit is an adenosine diphosphate (ADP)-ribosyl transferase, which accesses the cell cytosol to ADP-ribosylate the regulatory G protein (G Sα) ( de Haan et al., 1998) constitutively to activate adenylate cyclase, to generate cyclic adenosine monophosphate (cAMP) for protein kinase A-mediated activation of the cystic fibrosis … charcoal suit navy tieCholera toxin (also known as choleragen and sometimes abbreviated to CTX, Ctx or CT) is an AB5 multimeric protein complex secreted by the bacterium Vibrio cholerae. CTX is responsible for the massive, watery diarrhea characteristic of cholera infection. It is a member of the heat-labile enterotoxin family. harrington 198
