First Case Report of Neisseria lactamica Causing Cavitary Lung Disease in an Adult Organ Transplant Recipient

Abstract

We describe a case of an adult organ recipient patient with a pulmonary cavitary lesion due to Neisseria lactamica, a harmless commensal organism that rarely causes human infection. To our knowledge, this is the first report of pulmonary disease caused by this organism and the second case of N. lactamica infection in an adult patient.
