The most common site for amoebiasis is:: (A) Sigmoid colon, (B) Transverse colon, (C) Caecum, (D) Liver
Answer is C. Amoebiasis: - MC site involved is caecum & ascending colon. - Caused by Entamoeba histolytica. - Dysentery develops when amoeba attach to colonic epithelium, induce apoptosis, invade crypts & burrow laterally into lamina propria. - This recruits neutrophils, causes tissue damage, & create a flask-shaped ulcer with narrow neck & broad base.
