AI Article Synopsis
- - A 2-month-old girl experienced bacteremia from a rare pathogen after showing symptoms like diarrhea, poor oral intake, and vomiting; she was initially diagnosed with acute enterocolitis.
- - Blood cultures identified Gram-negative cocci, later confirmed as a specific strain through advanced genetic analysis methods, which was challenging with standard tests.
- - The infant was treated successfully with cefotaxime and diagnosed later with a non-IgE-mediated gastrointestinal food allergy, highlighting the need for detailed studies to understand the pathogenicity of this rare pathogen in humans.
Article Abstract
is rare pathogen, and its pathogenicity to humans has been unknown. We describe an infant with bacteremia caused by . The patient was a 2-month-old girl presented with diarrhea, poor oral intake, and vomiting. The patient was tentatively diagnosed with acute enterocolitis. After admission, the patient developed a fever and blood culture yielded Gram-negative cocci, first determined to be by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. However, genetic analysis of 16S rRNA allowed its identification as (GenBank accession number is OQ547240). Other housekeeping genes such as , and also identified the isolated strain as . The patient was successfully treated with cefotaxime without sequelae. Later, the patient was diagnosed as non-IgE-mediated gastrointestinal food allergy. Our experience indicated that is a potential human pathogen that can cause invasive infections even in infants and children. Identification of is difficult with routine conventional tests, and detailed studies including genetic analyses are necessary to clarify the pathogenicity of in humans.

Department of Hepatobiliary Surgery, Panzhihua Central Hospital, Sichuan, China.
This study aims to explore the pathogenic potential of as a rare pathogen in immunocompetent individuals and to analyze how mental health status may influence susceptibility to infection. We report a case of bacteremia in a 31-year-old immunocompetent female who developed infection during an episode of severe depression. Although the patient exhibited self-harm tendencies, a thorough physical examination did not reveal any external wounds or signs of injury.

Article Synopsis
- Bloodstream infections need quick bacterial identification for effective treatment, with traditional methods being slow.
- The study compared direct identification using MALDI-TOF MS with the post-culture method, finding that while direct identification had a lower success rate (64.8%), it provided results in under an hour.
- Despite its limitations, the direct method could significantly enhance diagnosis speed, making it a potentially valuable tool in conjunction with established methods.
[Real-time rectal swab Xpert Carba-R assay for early warning of CRO bloodstream infection in patients undergoing hematopoietic stem cell transplant: a clinical feasibility study].

This study aimed to analyze the homology between carbapenem-resistant organisms (CRO) intestinal colonization strains and bloodstream infection (BSI) strains in patients undergoing hematopoietic stem cell transplantation (HSCT), confirming the clinical use of the real-time rectal swab Xpert Carba-R assay, and investigate its feasibility in early warning of BSI. Drug-resistant strains obtained from rectal swabs and blood culture samples of patients undergoing the same HSCT from January 2021 to December 2021 were collected and analyzed. The homology of the CRO intestinal colonization and BSI strains was confirmed using strain identification, antimicrobial resistance phenotyping, whole genome sequencing (WGS), multilocus sequence typing (MLST), and carbapenemase type identification.

This study aimed to analyze the clinical and molecular characteristics of carbapenem-resistant Enterobacteriaceae (CRE) bloodstream infection (BSI) in patients with hematological diseases and to explore prognostic risk factors. This retrospective study included patients with hematologic diseases with CRE BSI at the Institute of Hematology and Blood Diseases Hospital from January 2015 to December 2022. The clinical features, carbapenemase test results, antimicrobial treatments, and outcomes were analyzed.
