AI Article Synopsis
- Bacteremia caused by a rare opportunistic agent accounts for 0.5-2% of positive blood cultures and is particularly dangerous for immunocompromised patients.
- A 74-year-old woman with an abdominal infection and recurrent ovarian tumor underwent successful treatment after being diagnosed with this infection, confirmed through blood cultures and advanced identification techniques.
- This case marks the first report of such bacteremia in China and highlights the importance of recognizing these infections, as well as the use of MALDI-TOF MS for identification in clinical settings.
Article Abstract
Background: Bacteremia caused by is an extremely rare infection that accounts for 0.5-2% of all positive blood cultures. is an opportunistic agent that is highly lethal in immunocompromised or epithelial barrier disruption hosts.
Case Presentation: A 74-year-old woman was admitted to our hospital with a high fever. The patient was diagnosed with an abdominal infection after a bowel invasion and recurrence of an ovarian tumor after surgery. Blood sample culturing yielded transparent, smooth, moist, slightly raised colonies without a hemolytic ring. was identified by gram staining and MALDI-TOF MS. 16S rRNA gene sequencing confirmed a sequence homologous to in the GenBank database. Drug susceptibility testing showed that was sensitive to cefoxitin, clindamycin, imipenem, meropenem, metronidazole, and vancomycin. After treatment, the patient's body temperature was normal and she was discharged from the hospital.
Conclusion: This is the first case report of bacteremia caused by in China and also the first report of identifying in clinical specimens by MALDI-TOF MS. This case study could increase the awareness of these infections in China.

is a predominant cause of post-operative surgical site infections and persistent bacteremia. Here, we describe a patient who experienced three episodes of infection over a period of 4 months following a total knee arthroplasty. The initial bloodstream isolate (SAB-0429) was a clonal complex 5 (CC5) and methicillin-resistant (MRSA), whereas two subsequent isolates (SAB-0485 and SAB-0495) were CC5 isolates but methicillin-sensitive .

A 70-year-old man developed intermittent fever with chills, severe anorexia, generalized weakness, and mild exertional difficulty in breathing following posterior chamber intraocular lens replacement surgery for a mature white cataract in the left eye. Laboratory tests revealed persistent negative blood cultures, normocytic and normochromic anemia, neutrophilia, and elevated inflammatory markers despite multiple courses of antibiotics. All other investigations conducted to identify the cause of prolonged fever, including transthoracic echocardiography, were negative.

Background: The optimal pharmacokinetic and pharmacodynamic (PK/PD) parameters of vancomycin that can improve outcomes in enterococcal infections remain controversial. To clarify the therapeutic target for this antibiotic, this study aimed to determine vancomycin PK/PD parameters associated with efficacy in the early (during 72 h) or later (after 72 h) phase of treatment and nephrotoxicity in enterococcal bloodstream infection patients.
Methods: This multicenter retrospective study reviewed medical records of patients with enterococcal bloodstream infections treated with intravenous vancomycin infusion for at least 72 h between January 2016 and March 2024 at Phramongkutklao Hospital or Nopparatrajathanee Hospital in Bangkok, and Rachaburi Hospital in Rachaburi Province, Thailand.

Enterococcus faecalis is responsible for numerous serious infections, and treatment options often include ampicillin combined with an aminoglycoside or dual beta-lactam therapy with ampicillin and a third-generation cephalosporin. The mechanism of dual beta-lactam therapy relies on the saturation of penicillin-binding proteins (PBPs). Ceftobiprole exhibits high affinity binding to nearly all E.
