Genomic insights into antibiotic-resistant non-typhoidal Salmonella isolates from outpatients in Minhang District in Shanghai.
Article in Communications medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
backgroundSalmonella enterica (S. enterica) causes tens of thousands of cases of diarrheal disease worldwide each year. However, our understanding of the genome and transmission dynamics of S. enterica in Minhang District in Shanghai, China is still insufficient. This study is aimed to better understand the population structure, antibiotic resistance patterns, and evolution dynamics of local strains.
methodsWe sequenced 458 S. enterica strains from outpatients at Minhang District Central Hospital in Shanghai, China, from 2012 to 2021. Bioinformatics analyses on antibiotic resistance genes, virulence factors, mobile genetic elements, pathogenic islands, and phylogenetic relationships were performed.
resultsHere we show that two dominant serovars are S. Enteritidis and S. Typhimurium isolated from outpatients in Minhang District in Shanghai, China. A total of 40 serovars and 53 sequence types (STs) are identified, two S. Montevideo strains isolated in 2013 belong to a newly identified ST10844, which is firstly identified in Minhang District in Shanghai, China. More than half of the isolates show resistance to fluoroquinolones and beta-lactams. Notably, 259 (56.6%) of the 458 isolates exhibit a multidrug-resistant pattern. Third-generation cephalosporin resistance gene bla
conclusionsThese results suggest local expansion and evolution in Salmonella occurred in Shanghai, China, and the underlying emergence of the undefined multidrug-resistant clone. Our findings enlarge the knowledge of local epidemics of Salmonella, especially S. Enteritidis and S. Typhimurium in Shanghai, and provide a piece of useful baseline information for future whole-genome sequencing surveillance.
