(1) There are no pus cells in the stool, thereby ruling out a bacterial diarrhea like shigella dysentery.(2) Direct inoculation of culture plates at the bedside is the most efficient means of isolating shigella from the dysentery patients.(3) One reason is that some microbes - in particular, a bacterium called shigella - appear to form a sticky u2018biofilm,u2019 like dental plaque, that is difficult to remove.(4) The researchers found that shigella , the bacteria causing dysentery uses a Type III secretion system to inject proteins into human cells.(5) Illnesses caused by salmonella, shigella , E. coli, and vibrio bacteria can cause severe diarrhea and vomiting, both of which would lead to further dehydration.
