title: [Acute community acquired pneumopathy caused by Nocardia asteroides in a 93-year-old female patient].
abstract: BACKGROUND
  Lower respiratory tract infection (LRTI) by Nocardia species is most often considered as an opportunistic infection occurring mainly in middle-aged adults.
  
  
  METHODS
  A 93-year old woman without any significant comorbidity other than a mild asthma, presenting with a non-resolving pneumonia, was successfully treated for a community-acquired LRTI by Nocardia asteroides.
  
  
  CONCLUSIONS
  LRTI by Nocardia asteroides is a rare occurrence. Although more frequent in immuno-compromised patients (50 to 85% of cases reported), Nocardia asteroides infection also occurs in immuno-competent individuals. Very few reports describe LRTI infection by Nocardia sp. in the very old, and almost exclusively in patients with major co-morbidities or variable degrees of immuno-suppression.
