False-colour transmission electron micrograph (TEM) of Haemophilus influenzae (Pfeiffer's bacillus),a Gram negative,non-motile,non- sporing species of bacilli (rod-shaped bacteria). H. influenzae is exclusively a parasite of man,living in the upper respiratory tract of healthy individuals. Most sub-species are non-capsulate bacteria,but there are 6 types of capsulated strains (types a to f),of which type b is responsible for numerous incidences of bacterial meningitis in young infants. Other type b diseases include epiglottitis,a potential cause of fatal obstruction in the airways. Magnification: x16,000 at 35mm size,x32,000 at 6x7cm size | |
