Salmonella bacterium dividing. Coloured scanning electron micrograph (SEM) of of a Salmonella bacterium dividing. The two new daughter cells are seen at upper right and lower left, still joined by a thin connection (centre). Flagella, thin thread-like structures used by the bacteria to move, are also seen. Salmonella bacteria can cause food poisoning when they are eaten in contaminated food such as raw eggs. Given the right conditions, they can multiply rapidly. Symptoms include abdominal pain, nausea, diarrhoea and vomiting.
