Pseudomonas aeruginosa bacteria. Coloured scanning electron micrograph (SEM) of Pseudomonas aeruginosa bacteria. The bacteria were found on ciliated human nasal epithelium. These Gram- negative, rod-shaped bacteria move using hair- like flagellae. P. aeruginosa is common in the human intestine, but can cause serious wound, skin and urinary tract infections. It can also multiply in the warm, moist conditions found in baby incub- ators and ventilating machines and so be inhaled in large numbers. Such infections of the respirat- ory tract are usually harmless, but can result in dangerous pneumonia. Magnification unknown.
