The answer is C, A, D. Recently many cases of infective diarrhoea have been shown to be due to organisms of the Campylobacter group.

Antibiotic associated diarrhoea (pseudomembranous colitis) is due to infection by Clostridium difficile and the effects of its toxin on the mucosa.

The vibrio toxin stimulates adenyl cyclase activity which alters fluid and electrolyte balance between mucosal cells and gut lumen.

Enlargement of Peyer's patches is a feature of typhoid (B). Stool examination is essential for the diagnostic of amoebic dysentery (E).
