HAEMOPHILUS INFLUENZAE TYPE B SEPTICAEMIA

In the period November 1967 to September 1968 Haemophilus influenzae type b was isolated from the blood of 11 young children. Only three of these presented with meningitis ; others had septic arthritis, oesteomyelitis, subcutaneous abscesses, cellulitis, respiratory infections, and undifferentiated pyrexia. During the preceding five years H. influenzae type b was isolated from the blood cultures of 15 patients, and all but two of these were cases of meningitis. Blood culture has proved of value in establishing the role of H. influenzae type b in a broad spectrum of acute infections, and the suggestion is made that meningitis may represent only a minority of cases of haemophilus septicaemia. Because H. influenzae is resistant to some antibiotics bacteriological diagnosis of such cases is important if the correct treatment is to be given. © 1969, British Medical Journal Publishing Group.
