Gordonia spp. bacteremia rarely occurs in children, and no treatment guidelines have been established. Herein, we describe 2 cases of Gordonia sp. bacteremia in a short period of time in the pediatric ward of Kurume University Hospital. Both cases involved hematologic oncological diseases and the use of central venous catheters. Suspecting an outbreak caused by the same bacterium type, 16S rRNA gene sequencing was
performed for isolates obtained from each patient. The results of the 16S rRNA gene sequencing revealed that the bacterium responsible for the first case was G. sputi and in the second case the causative bacterium was G. polyisoprenivorans. Therefore, the prospect of an outbreak was ruled out. Molecular biological investigation is important for the verification of invasive infections caused by rare bacteria.
