Acute Cystitis Caused by Commensal Neisseria oralis: A Case Report and Review of the Literature.

BACKGROUND

Neisseria are usually harmless inhabitants of otherwise asymptomatic persons' upper respiratory mucosal surfaces.

METHOD: It is, therefore, expected that a disturbance in the physiology leads to nongonococcal, non-meningococcal Neisseria becoming pathogenic.

RESULT: We report the case of a diabetic man who initially presented with nonspecific symptoms and was later found to have cystitis caused by N. oralis.

CONCLUSION

We also review the pertinent literature and discuss available evidence on pathophysiological mechanisms of infection with such commensal bacteria.
