| Abstract |
A 91-year-old female was admitted due to fever and dyspnea. She was diagnosed with septic shock, disseminated intravascular coagulation and acute pyelonephritis. Gram-positive bacilli were isolated from her urine culture and two sets of blood cultures obtained on admission. The isolated bacterial colonies showed catalase-negative, facultative anaerobic and coryneform bacteria, but not beta-hemolysis. They were recognized as Arcanobacterium pyogenes by BBL Crystal GP (Becton, Dickinson).
They showed beta-glucrunidase-negative and lactose-negative, although A. pyogenese usually doesn't. We asked the department of microbiology, Saga University to identify them. Finally they were identified as Trueperella bernardiae with MALDI Biotyper (BRUKER) and 16S rRNA gene sequence analyses. We report herein on a rare case of acute pyelonephritis with bacteremia caused by T. bernardiae. |
