WebJan 11, 2024 · multiply by simple binary fission. The trophozoites secrete histolysin, which causes necrosis and destruction of the host’s tissue and helps the parasite derive nourishment from the dissolved dead tissues [13]. However, some non-invasive trophozoites remain in the lumen of the large intestine and multiply by binary fission. WebThe four nuclei then undergo mitotic division finally giving rise to 8 metacystic trophozoites. These metacystic trophozoites feed on the intestinal epithelium and develop into mature trophozoites. The feeding process involves the production of tissue dissolving secretions (histolysin) which are responsible for the intestinal ulcers. lyle and scott big and tall sale
