Abstract

A 77-year-old man, initially diagnosed with pneumonia presented with fever and was administered continuous amino acid preparations and meropenem. Bacillus cereus was isolated from two separate sets of blood cultures, leading to a diagnosis of catheter-related bloodstream infection. Despite treatment with teicoplanin (TEIC) and additional antibiotics, B. cereus was continuously yielded from blood cultures for approximately four weeks. Ultimately, the patient was successfully treated with a combination of TEIC and clindamycin for six weeks, along with gentamicin for two weeks. This case report further reviews 17 cases of persistent B. cereus bacteremia. These cases provide valuable insights into the management of challenging cases of B. cereus bacteremia.

延长蜡样芽孢杆菌菌血症1例报告及文献复习

一名77岁男子，最初诊断为肺炎，出现发烧，并给予连续氨基酸制剂和美罗培南。蜡样芽孢杆菌从两组不同的血液培养中分离出来，导致导管相关血流感染的诊断。尽管使用teicoplanin （TEIC）和其他抗生素治疗，蜡样芽孢杆菌在大约四周的血培养中持续产生。最终，患者成功地接受了TEIC和克林霉素联合治疗6周，庆大霉素联合治疗2周。本病例报告进一步回顾了17例持续性蜡样芽孢杆菌菌血症。这些病例为蜡样芽孢杆菌菌血症的管理提供了有价值的见解。

期刊介绍： The Journal of Infection and Chemotherapy (JIC) — official journal of the Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases — welcomes original papers, laboratory or clinical, as well as case reports, notes, committee reports, surveillance and guidelines from all parts of the world on all aspects of chemotherapy, covering the pathogenesis, diagnosis, treatment, and control of infection, including treatment with anticancer drugs. Experimental studies on animal models and pharmacokinetics, and reports on epidemiology and clinical trials are particularly welcome.
