title: First report of a Wautersiella falsenii isolated from the urine of an infant with pyelonephritis.
abstract: Here, we report the first isolation of Wautersiella falsenii from the urine of an infant with a complicated urinary tract infection. W. falsenii was correctly identified by matrix-assisted laser desorption ionisation time of flight mass spectrometry. The identification was confirmed by 16S polymerase chain reaction. Susceptibility test results of this isolate are reported. Ciprofloxacin treatment resulted in clinical and microbiological improvement.
