Lactobacillus delbrueckii urinary tract infection in a male patient: a case report.
Introduction: Lactobacilli are Gram-positive rods, commensals of the normal human flora. Generally, these lactic acid-producing bacteria are considered contaminants, however over the last years their clinical relevance is reevaluated. Lactobacillus delbrueckii is very rarely isolated and only a few cases of L. delbrueckii urinary tract infections (UTIs) have been reported, mainly in females.
Case report: We report the case of a L. delbrueckii UTI in an 82-year-old male suffering from benign prostate hyperplasia with repeated episodes of acute urinary retention over the last month before presenting to our hospital. The catheter urine culture grew >105 CFUs/mL of pure L. delbrueckii on Columbia CNA blood agar and on Trypticase soy agar. Identification was achieved by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS), using VITEK MS (bioMérieux, France). The patient was successfully treated with cefixime for ten days. A follow-up urine culture performed 7 days after antibiotic discontinuation was sterile.
Conclusions: To our knowledge the present is the second case of L. delbrueckii urinary tract infection in a male patient. Further cases are required to confirm the clinical significance of these unusual pathogens and their involvement in human urinary tract infections.
