Haemophilus influenzae. Coloured scanning electron micrograph showing Haemophilus influenzae bacteria (rod-like and blue) lying on human nasal epithelium. It is a Gram-negative bacterium and is an important pathogen in children aged one to five years. It colonises the upper respiratory tract in virtually all humans within the first few months of life. It may spread locally and cause diseases of the lower respiratory tract such as bronchitis and pneumonia. The Haemophilus influenzae type b causes a wide range of diseases in children; these include meningitis, epiglottitis, blood poisoning and joint and bone infections.
