Bacteria is one of the prokaryotic domains, the other being Archaea. Since it is a prokaryote, it has no nuclear membrane, no organelles except for ribosomes in the cytoplasm and all its genetic material (DNA) is coiled up strands. It is also single-cellular. The domain consists of bacterium, more than one being called bacteria. Bacteria is rod-shaped and can appear in chains. Bacteria is involved in infections, diseases, fermentation, nitrogen fixation or putrefaction.
Above is a picture of feet because bacteria, whether good or bad, is already on the skin in general. There's especially a lot of bacteria around the feet which explains why our feet smell bad after taking our sneakers off. Since the bacteria was in a moist, dark and warm area, it was able to send off its smell which is what gives our feet and socks the extremely bad odor.
