| Abstract |
We report a case of bacteremia caused by Gordonia sputi that was difficult to detect on routine microbiologic examination. A six-year-old girl developed a fever while recuperating at home with an indwelling central venous catheter. Despite a positive signal in a blood culture system, Gram staining did not reveal the presence of microorganisms. Therefore, we determined that it was a false-positive signal. However, when the bottles were sub cultured and reloaded into the system, they again produced a positive signal. Based on the morphology of the colonies in the subculture and the results of various stains, we determined that the bacterium was a mildly acid-fast species. In addition, mass spectrometry and genetic analysis confirmed the G. sputi infection. G. sputi is a gram-positive, mildly acid-fast bacilli that is widely distributed in water and soil. Catheter-related infections with Gordonia sp. occur in immunocompromised patients. Therefore, estimation of the causative microorganism based on the patient history, colony morphology, and staining is important for prompt reporting. In addition, we must consider the presence of an organism when positive signals are detected in multiple bottle sets or times in the culture system. |
