title: Urinary tract infection with Corynebacterium aurimucosum after urethroplasty stricture of the urethra: a case report.
abstract: BACKGROUND
  Corynebacteria have an important place among the commensal flora of the skin and mucous membranes. Except for Corynebacterium diphtheriae, they were once considered contaminants of mucosa. Recent publications in medical bacteriology have highlighted the importance of several species, such as C. aurimucosum. To the best of our knowledge, we report the first isolation of this strain from urine.
  
  
  METHODS
  We report a case of a patient with a urinary tract infection with C. aurimucosum. We isolated this bacterium from a 52-year-old man of Wolof ethniticity (an ethnic group in Senegal, West Africa) at the regional hospital of Saint Louis, Senegal. Microscopic examination of his total urine sample showed coryneform Gram-positive bacilli associated with a high leukocyte reaction. After repeated isolation of the corynebacteria in three samples from the patient's urine, it was identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The strain was susceptible to antibiotics, except for penicillin and co-trimoxazole. The potential infectious role of these commensal species in several infections should be taken into consideration.
  
  
  CONCLUSIONS
  This case highlights the significant proportion of species in the genus Corynebacterium other than dyphteriae in the infectious process. The use of mass spectrometry for identification highlights the originality of this work and the importance of these new diagnostic tools that are unavailable in most health facilities of countries with limited resources. We share the results of our method of identification of the isolated bacteria. This case should prompt attention to these rare bacteria, which can cause severe infections.
