Cholera Bacteria

This image shows the cholera bacteria Vibrio cholerae serotype 01. Even without staining, it is possible to clearly see the distinctive curved form of each cholera bacterium as well as the single flagella at the end of the body. It is possible that the reason why the bacterium at the bottom of the image appears darker than the one in the center is that the bacterium at the bottom was damaged in the air-drying process.
