Bacteremia by colistin-resistant Acinetobacter baumannii isolate: a case report.

J Med Case Rep

Bacterial Molecular Genetics Laboratory, Universidad El Bosque, Bogotá DC, Colombia.

Published: May 2019

Background: Carbapenem-resistant Acinetobacter baumannii infections are a major public health problem worldwide, requiring the use of "old" antibiotics such as polymyxin B and E (colistin). However, there is concern regarding the emergence of isolates resistant to these antibiotics.

Case Presentation: We report a case of a 64-year-old mestizo man hospitalized in an intensive care unit of a health institution in Colombia with identification and clinical and molecular typing of a colistin- and carbapenem-resistant A. baumannii isolate with mechanisms of resistance to colistin not previously reported, causing bacteremia.

Conclusions: We have identified a strain of A. baumannii with mechanisms of resistance to colistin not previously reported in a patient with bacteremia who required treatment with multiple antibiotic schemes and had an adequate response.

Clinical evaluation of a multiplex droplet digital PCR for diagnosing suspected bloodstream infections: a prospective study.

Front Cell Infect Microbiol

January 2025

Department of Clinical Laboratory, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.

Background: Though droplet digital PCR (ddPCR) has emerged as a promising tool for early pathogen detection in bloodstream infections (BSIs), more studies are needed to support its clinical application widely due to different ddPCR platforms with discrepant diagnostic performance. Additionally, there is still a lack of clinical data to reveal the association between pathogen loads detected by ddPCR and corresponding BSIs.

Methods: In this prospective study, 173 patients with suspected BSIs were enrolled.

Electronic address:

Endolysins have drawn considerable attention as viable modalities for antibiotic use. The most significant obstacle for Gram-negative targeting endolysins is the presence of the outer membrane barrier. A heterologously expressed endolysin encoded by bacteriophage PBPA90 infecting Pseudomonas aeruginosa exhibited intrinsic antibacterial activity against P.
