Genomic characteristics of antimicrobial resistance and virulence factors of carbapenem-resistant Stutzerimonas nitrititolerans isolated from the clinical specimen.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStutzerimonas nitrititolerans (S. nitrititolerans) is a rare human pathogenic bacterium and has been inadequately explored at the genomic level. Here, we report the first case of carbapenem-resistant S. nitrititolerans isolated from the peritoneal dialysis fluid of a patient with chronic renal failure. This study analyzed the genomic features, antimicrobial resistance, and virulence factors of the isolated strain through whole genome sequencing (WGS).
methodsThe bacterial isolate from the peritoneal dialysis fluid was named PDI170223, and preliminary identification was conducted through Matrix-assisted laser desorption ionization/time of flight mass spectrometry (MALDI-TOF MS). WGS of the strain PDI170223 was performed using the Illumina platform, and a phylogenetic tree was constructed based on the 16S rRNA gene sequences. Antimicrobial susceptibility test (AST) was conducted using the TDR-200B2 automatic bacteria identification/drug sensitivity tester.
resultsS. nitrititolerans may emerge as a human pathogen due to its numerous virulence genes, including those encoding toxins, and those involved in flagellum and biofilm formation. The AST results revealed that the strain is multidrug- and carbapenem-resistant. The antimicrobial resistance genes of S. nitrititolerans are complex and diverse, including efflux pump genes and β⁃lactam resistance genes.
conclusionThe analysis of virulence factors and antimicrobial resistance of S. nitrititolerans provides clinical insight into the pathogenicity and potential risks of this bacterium. It is crucial to explore the mechanisms through which S. nitrititolerans causes diseases and maintains its antimicrobial resistance, thereby contributing to development of effective treatment and prevention strategies.
