Double-carbapenemase-producing Enterobacteriaceae: complete genome sequencing of isolates from hospitals in Paraguay, 2021.
Article in Revista peruana de medicina experimental y salud publica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMotivation for the study. To generate knowledge about the current situation of antimicrobial resistance in Enterobacteriaceae using whole genome sequencing. Main findings. This study presents the first genome sequencing of double-carbapenemase-producing Enterobacteriaceae from patients with extended hospital stays in Paraguay. Of the seven double-carbapenemase-producing Enterobacteriaceae isolates, six were Klebsiella subsp pneumoniae. Implications. Our findings highlight the urgent need to strengthen measures to prevent and control healthcareassociated infections in order to prevent the spread of these highly resistant bacteria. OBJECTIVES.: To describe the whole genome sequencing of double-carbapenemase-producing Enterobacteriaceae isolates circulating in Paraguay. MATERIALS AND METHODS.: We conducted genomic studies on seven Enterobacteriaceae isolates, previously confirmed as double-carbapenemase producers by PCR, from patients with extended hospital stays and broad-spectrum antimicrobial treatment in seven hospitals in Paraguay. Genome sequencing included Unicycler assembly and multilocus sequence typing (MLST). RESULTS.: Of the seven Enterobacterales isolates producing dual carbapenemases, six were Klebsiella pneumoniae subsp. pneumoniae and one was Enterobacter cloacae subsp. cloacae. The co-production of bla KPC-2/bla NDM-1 and bla KPC-2/bla NDM-5 was confirmed in K. pneumoniae. We found co-production of bla NDM-1/bla OXA-163 in E. cloacae, along with other antimicrobial resistance genes of chromosomal and plasmid origin. The MLST sequence types of the K. pneumoniae isolates were ST11, ST15, ST133, ST273, and ST1303, and that of E. cloacae was ST976. Two of the six K. pneumoniae ST11 isolates, from two different hospitals in the capital, were genetically related and both carried bla KPC-2 and bla NDM-5. CONCLUSIONS.: We report the first genome sequencing of double-carbapenemase-producing Enterobacterales from patients with extended hospital stays in Paraguay. The analysis revealed diverse resistance profiles and clones, carriage of multiple carbapenemases, and other resistance genes of chromosomal and plasmid origin. These findings emphasize the need to strengthen hospital infection control and implement effective therapeutic interventions.
