title: Aerococcus urinae, a cause of cystitis with malodorous urine in a child: clinical and microbiological challenges.
abstract: Introduction.An infection of the lower urinary tract associated with an extremely unpleasant odour due toAerococcus urinaein an otherwise healthy 5-year-old boy is described herein.Case presentation.Interestingly, imaging examination revealed the presence of a bladder diverticulum. Routine microbiological examination based on Gram staining, colony morphology and catalase reactivity suggested that the responsible pathogen could belong either to staphylococci, α-haemolytic streptococci or enterococci, which are more common urine isolates. Of note is that the VITEK 2 automated system could not identify the micro-organism. Susceptibility testing showed full sensitivity to β-lactam antibiotics and resistance to trimethoprim/sulfamethoxazole. The isolate was subjected to 16S rRNA gene sequence analysis because of its unusual characteristics. It was identified asA. urinaeand the sequence was deposited in GenBank under the accession number KU207150.Conclusion.A. urinaeshould be considered as a causative agent of urinary-tract infection associated with malodorous urine.
