How does bacteria cause cell damage
WebToxins may damage the eukaryotic cell membrane by combining with some structural component, or otherwise alter its function. Many toxins combine with specific receptors on the surface membrane, frequently glycoproteins or gangliosides, and penetrate the cell to reach their intracellular target. A common mechanism of entry is absorptive endocytosis. WebSo we know that there are unbelievable numbers of bacteria inside of us, and some of them are good. So what about the bad ones?
