False colour scanning electron micrograph (SEM) of Haemophilus influenzae (Pfeiffer's bacillus),showing 2 individuals of the Gram negative,non- motile,non-sporing species of bacilli (rod-shaped bacteria). H. influenzae is exclusively a para of man,living in the 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 (inflammation of epiglottis,causing potential obstruction in airflow to lungs). Magnification: X 11,700 (35mm). Red bacteria on orange background | |
