Genomic characterization of multidrug-resistant Klebsiella pneumoniae clinical isolates from India.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Klebsiella pneumoniae is an emerging global threat driven by rising antimicrobial resistance and the spread of hypervirulent lineages. To investigate its evolving genomic landscape in India, we characterized two clinical K. pneumoniae isolates, NG_299 and NG_300, obtained from a tertiary care hospital in Pune and analyzed them in the context of Indian and global isolate collections. Comprehensive phenotypic and genomic analyses were performed using antimicrobial susceptibility testing, Illumina NovaSeq whole-genome sequencing and PCR-based confirmation of resistance and virulence markers. Both isolates exhibited multidrug resistance, remaining susceptible to only a limited subset of tested antibiotics. NG_299 (ST231) was susceptible to amikacin, colistin, and trimethoprim/sulfamethoxazole, whereas NG_300 (ST20) was found to be susceptible only to colistin and trimethoprim/sulfamethoxazole. Genomic profiling revealed thirty-two resistance determinants in NG_299 and fifty-two in NG_300, both of which produce extended-spectrum β-lactamases. Carbapenem resistance was linked to metallo-β-lactamase activity and the presence of AmpC was confirmed by antimicrobial susceptibility testing and PCR in NG_300. Pan-genome resistome analysis of global isolates identified conserved core genes (CRP, PhoP, rpoB) and a sparse occurrence of AMR genes (NDM, CTX-M, KPC, OXA, mcr) associated with horizontal gene transfer. Notably, NDM and CTX-M were present in both study isolates, with OXA variants detected in NG_299. Distinct missense mutations within shared resistance genes highlighted independent evolutionary trajectories. Both isolates carried virulence factors associated with adhesion, biofilm formation, iron acquisition, and secretion systems, including siderophores. Plasmid analysis identified IncF replicons in both isolates and blaNDM-5 on an IncFII plasmid in NG_299. These findings document the circulation of multidrug-resistant K. pneumoniae in Pune and underscore the urgent need for strengthened genomic surveillance.
