Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, Volume 57, Issue 9, Page 1554-1564, September 2026.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

First Description of an RND-Type Multidrug Efflux Pump in Achromobacter xylosoxidans, AxyABM [PDF]

Antimicrobial Agents and Chemotherapy, 2011
ABSTRACT Achromobacter xylosoxidans is an emerging pathogen in cystic fibrosis patients. The multidrug resistance of these bacteria remains poorly understood. We have characterized in a clinical strain the first resistance-nodulation-cell division (RND)-type multidrug efflux pump in this species: AxyABM.

Reducing bacterial antibiotic resistance by targeting bacterial metabolic pathways and disrupting RND efflux pump activity

Iberoamerican Journal of Medicine, 2022
Antibiotic resistance is a significant issue for the medical community, worldwide. Many bacteria develop drug resistance by utilizing multidrug resistant or MDR efflux pumps that can export antibiotics from bacterial cells.

Genomic Insights Into the Multimetal Resilience and Biofilm‐Templated Nanorod Biosynthesis of Stenotrophomonas bentonitica BII‐R7: Bioremediation and Green Nanotechnology Implications

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Biofilm extracellular polymeric substances (EPS) in Stenotrophomonas bentonitica BII‐R7 direct the formation of crystalline trigonal selenium nanorods. Comparative genomics identifies a unique genetic toolkit underpinning EPS composition and metal resilience, positioning this strain as a platform for bioremediation and green nanomaterial synthesis ...

Elucidation of the structure and molecular mechanism of the tripartite multidrug efflux pumps in the Gram-negative pathogens: Vibrio cholerae and Neisseria gonorrhoeae [PDF]

, 2006
In bacteria, multidrug efflux systems have been identified as significant determinants of resistance recently. These resistance pumps are widely distributed in bacterial species and many pathogenic bacteria posses them, which play an important role in ...

ROLE OF RND-EFFLUX PUMP IN LEVOFLOXACIN RESISTANCE AMONG ACINETOBACTER BAUMANNII

IRAQI JOURNAL OF AGRICULTURAL SCIENCES, 2022
In this study out of 130 different clinical specimens, 70 Acinetobacter baumannii were collected from hospitalized patients. Then; all the isolates were characterized using biochemical tests and confirmed by using the Vitek II compact system. All isolates of Acinetobacter baumannii were subjected to the disc diffusion method to determine it's a ...

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump.

PLoS ONE, 2020
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.
