| Abstract |
Previous reports have suggested that urinary tract infections caused by pneumococci are related to urinary tract malformations. The detection rate of pneumococci in urine samples in our hospital has been 4/5,390 (0.07%) over the past 7 years and 6 months. However, only one true urinary tract infection was diagnosed, and the others were determined to be contaminants. The true infection was diagnosed in a 2-year-old girl with a cloacal malformation, percutaneous vaginostomy, and bilateral hydronephrosis. She underwent a left ureteral stent exchange under general anesthesia. The following day, she was admitted to our hospital because of fever and was diagnosed with left pyelonephritis based on the results of enhanced abdominal computed tomography and evidence of pyuria. The urinary gram stain revealed gram positive cocci in chains, which were subsequently identified as Streptococcus pneumoniae serotype 34, a non-vaccine serotype, and ST 7388 by multi-locus sequence typing analysis. There were 103 CFU/mL in the urine culture. However, we have not determined the serotypes specific to urinary tract infections in this study. When pneumococci are identified in urine specimens, it is necessary to distinguish contaminants from infectious bacteria. However, if urinary tract anomalies exist, it is possible that pneumococci are the causative bacteria of infection. |
