RT Journal Article SR Electronic T1 Three cases of meningococcal pneumonia. JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 927 OP 929 DO 10.1136/thx.52.10.927 VO 52 IS 10 A1 E M Jones A1 N M Brown A1 J E Harvey A1 D S Reeves A1 A P MacGowan YR 1997 UL http://thorax.bmj.com/content/52/10/927.abstract AB Three cases of pneumonia due to Neisseria meningitidis are described. In all three cases the organism was isolated only from blood cultures, but in the presence of good clinical and radiological evidence of pneumonia. The isolates belonged to three different serogroups: B type 2b, C, and Y. The cases illustrate the fact that N meningitidis can cause pneumonia and that culture of blood plays an important part in the diagnosis. Clinically there is nothing to differentiate meningococcal pneumonia from other causes of community acquired pneumonia. Predisposing factors include aspiration, immunosuppression, influenza, and adenovirus infections. When diagnosed, pneumonia due to N meningitidis should be notified and prophylaxis given as for meningitis or septicaemia.
