False-colour transmission electron micrograph of the bacteria Campylobacter jejuni, causative agent of food poisoning in humans. These Gram-negative bacteria, curved or spiral in shape, have flagellae (whip- like tails) at either pole of the cell giving them a darting mobility. C. jejuni is a common cause of gastroenteritis in humans, especially children and young adults. Contaminated poultry, meat and milk are sources of infection. Symptoms include fever and acute abdominal pain, followed by watery and often bloody diarrhoea. Recovery usually is rapid. Magnification: x5,700 at 6x7cm size. Mag was converted wrongly. RV.1 10 01.
