title: Severe pneumonia due to Nocardia otitidiscaviarum identified by mass spectroscopy in a cotton farmer: A case report and literature review.
abstract: BACKGROUND
  Nocardia species are aerobic saprophytic bacilli. Among Nocardia species, Nocardia otitidiscaviarum (N otitidiscaviarum) is rarely reported in pulmonary infection.
  
  
  METHODS
  We reported a case of N otitidiscaviarum pneumonia in a cotton farmer.
  
  
  METHODS
  N otitidiscaviarum pneumonia was identified by mass spectroscopy.
  
  
  METHODS
  Combined treatments (amikacin, imipenem and trimethoprim-sulfamethoxazole) were administered after identification of N otitidiscaviarum.
  
  
  RESULTS
  The patient eventually died from severe respiratory insufficiency in the hospital.
  
  
  CONCLUSIONS
  Early precise diagnosis and prompt combined therapy are of vital importance in severe Nocardia pulmonary infection.
