| Abstract |
The case, 7 year-old children, was hospitalized for purposes of scrutinizing the abdominal mass in April 2006. Wilms'tumor was diagnosed by the pathological examination. The tumors were metastasized to some organs including the lungs, and the patient initiated chemotherapy. In March 2007, the blood culture test detected Gram-positive bacteria. The morphology of the bacteria with gram staining looked bacillar in the blood culture bottle, while the bacteria showed a coccoid form following the subculture with sheep blood agar media. Since these varieties of the bacterial morphology with the gram staining made the identification of bacteria difficult, we asked the external institution to identify the bacteria. Successfully the bacteria were identified as R. equi by the genetic testing. Although the bacteria were detected at the occasional fever of the patient after the initiation of antibiotic therapy, the bacteria were no longer detected after January 2008. Carbapenems and macrolides were administered to the patient, the bacteria were not detected at the blood culture. In case of the difficult identification of the bacteria by own institution, it is indispensable to request the identification of bacteria, to the external institutions, so that patients receive treatment with the appropriate antibiotics. Thus, this case makes us realize the significance of appropriate antibiotic therapy based on the identification of the pathogenic bacteria, again. |
