MgrB variants in colistin-susceptible and colistin-resistant Klebsiella pneumoniae ST258

Journal of Microbiology, Immunology and Infection, 2017
Resistance determinants of a colistin susceptible and five colistin resistant Klebsiella pneumoniae ST258 from a Hungarian outbreak were investigated. A novel MgrB variant in colistin susceptible strain was found. Elevated phoP and arn gene expressions and wild-type PmrB in all colistin resistant K. pneumoniae were detected. All strains lacked mcr-1.

Clinical Use of Colistin Induces Cross-Resistance to Host Antimicrobials in Acinetobacter baumannii

mBio, 2013
The alarming rise in antibiotic resistance has led to an increase in patient mortality and health care costs. This problem is compounded by the absence of new antibiotics close to regulatory approval.

Whole Genome Characterization of Klebsiella Strains in European Hedgehogs and Human Nosocomial Settings Identified Shared Sequence Types, Antimicrobial Resistance Genes and Plasmids

Zoonoses and Public Health, EarlyView.
ABSTRACT Introduction Klebsiella pneumoniae is a pathogen associated with healthcare‐acquired infections and antimicrobial resistance (AMR) to beta‐lactams and carbapenems. Although wild animals are not typically exposed to antibiotics, they can harbour resistant strains. The European hedgehog (Erinaceus europaeus) is increasingly found in urban areas,

Colistin-resistant Pseudomonas aeruginosa clinical strains with defective biofilm formation

GMS Hygiene and Infection Control, 2019
Aim: Colistin is the only effective antibiotic in some cases of resistance to all tested antibiotics, even carbapenem. On the other hand, biofilm formation is one of the antibiotic resistance mechanisms in this bacterium.

Prevalence and Characteristics of Salmonella spp. by Production Stage in Integrated Broiler Operations in Korea

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Vertically integrated broiler production systems may facilitate the dissemination of Salmonella throughout the production chain. This study demonstrates that Salmonella persists and spreads across all stages of integrated broiler production, highlighting the need for rigorous biosecurity, hygiene and continuous monitoring throughout the entire ...

Evaluation of a Product Intended for Microbiological Control in Animal Production, and Its Combination With Halquinol

Animal Research and One Health, Volume 4, Issue 3, Page 302-313, August 2026.
Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of

Successful Rapid Desensitization to Ceftazidime/Avibactam in a Patient With Cystic Fibrosis and Multidrug‐Resistant Pseudomonas aeruginosa Pneumonia: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Ceftazidime/avibactam (CAZ‐AVI) is an important therapeutic option for multidrug‐resistant (MDR) Pseudomonas aeruginosa infections; however, hypersensitivity reactions may preclude its use and create significant therapeutic challenges. We report a 21‐year‐old woman with cystic fibrosis and recurrent MDR P.

Mutations in the pmrB gene constitute the major mechanism underlying chromosomally encoded colistin resistance in clinical Escherichia coli

Journal of Global Antimicrobial Resistance
Objectives: The mechanisms underlying chromosomally encoded colistin resistance in Escherichia coli remain insufficiently investigated. In this study, we investigated the contribution of various pmrB mutations from E.

Combination of Oral Doxycycline and Rifampin for Pan‐Drug Resistant Klebsiella pneumoniae Infection: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Pan‐drug resistant Klebsiella pneumoniae is a major therapeutic challenge, particularly when standard last‐line agents are unavailable or contraindicated. We report a 45‐year‐old man with multifocal osteomyelitis and persistent purulent wound discharge despite broad‐spectrum antibiotics, repeated debridement, and two sequential amputations ...
