Causes. Among the many strains of E. coli, only a few trigger diarrhea. One group of E. coli â which includes O157:H7 â produces a powerful toxin that damages the lining of the small intestine, which can cause bloody diarrhea.You develop an E. coli infection when you ingest this strain of bacteria.he most common way to acquire an E. coli infection is by eating contaminated food, such as: 1  Ground beef. 2  When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat. 3  Ground beef combines meat from many different animals, increasing the risk of contamination.
In biology, tissue is a cellular organizational level intermediate between cells and a complete organ. A tissue is an ensemble of similar cells from the same origin that together carry out a specific function.Organs are then formed by the functional grouping together of multiple tissues.The study of tissue is known as histology or, in connection with disease, histopathology. tissue is an ensemble of similar cells from the same origin that together carry out a specific function.
