Bacteremia Caused by Turicella otitidis in a Patient with Diffuse Large B-Cell Lymphoma by Dan Li, Wulin Shan, Chunyang Dai, Jinsong Kan, Ming Li, Meiling Yin

Background: Invasive Gram-positive bacilli infections are commonly encountered in immunocompromised patients. In this paper, we report a bacteremia caused by Turicella otitidis in a patient with diffuse large B-cell lymphoma.
Methods: Bacteria was identified by VITEK MALDI-TOF MS. Drug sensitivity was analyzed by disk diffusion method.
Results: MALDI-TOF MS data demonstrated that the infection bacteria was Turicella otitidis. Drug susceptibility data showed that Turicella otitidis was possibly sensitive to vancomycin, polymyxin B, and chloramphenicol. Body temperature of the patient dropped after administration of vancomycin. The data indicated that vancomycin could be used to treat the infections caused by Turicella otitidis.
Conclusions: MALDI-TOF MS can be used for the rapid and accurate identification of Turicella otitidis. Vancomycin can be used to treat the infection caused by Turicella otitidis. This study may provide a reference for the diagnosis and treatment of Turicella otitidis.
