Risk Factors of Blood Culture Positivity and Mortality in Bloodstream Infections: A Population‐Based Study of Patients With B‐Cell Malignancies

European Journal of Haematology, Volume 117, Issue 4, Page 1061-1071, October 2026.
ABSTRACT Background Bloodstream infections remain a major cause of mortality among cancer patients. Pathogen surveillance and risk stratification tools are key to improved management. This study describes trends in causative pathogens and explores risk factors for positive blood cultures (PBCs) and post‐infection mortality in cancer patients.

Comparison of virulence factors between ESBL and non-ESBL producing Klebsiella pneumoniae isolates

Iranian Journal of Microbiology
Background and Objectives: Klebsiella pneumoniae is an opportunistic pathogen responsible for causing nosocomial and community-acquired infections. Its pathogenicity is associated with a variety of virulence factors and antibiotic resistance. The aim of the present study was to compare virulence attributes between ESBL and non-ESBL producing isolates.

Extended-Spectrum Beta-Lactamases

Canadian Journal of Infectious Diseases and Medical Microbiology, 2006
The definition of extended-spectrum beta-lactamases (ESBLs) has expanded rapidly, in terms of both the number and the variety of enzymes. Bacteria bearing plasmidic ESBLs are spreading widely throughout the world.

Targeted mechanisms and novel therapeutic strategies against extended-spectrum beta-lactamases: From precise detection to intelligent management of bacterial resistance

Journal of Current Biomedical Reports
Extended-spectrum beta-lactamases (ESBLs) are enzymes that resist beta-lactam antibiotics, including penicillins, cephalosporins, and carbapenems, and are produced by a variety of bacteria, including Escherichia coli and Klebsiella pneumoniae.
