Highly drug-resistant Vibrio cholerae harbouring blaPER-7 isolated from travellers returning to England.
Article in The Journal of antimicrobial chemotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesThe current, seventh cholera pandemic (7PET) is notably different from the previous six, owing to its rapid global spread and increased transmission of antimicrobial resistance. The global emergence of MDR Vibrio cholerae is a public health concern. We aimed to interrogate WGS data from V. cholerae isolates referred to the UK Health Security Agency (formerly Public Health England, PHE) for the presence of blaPER-7 encoding resistance to the extended-spectrum cephalosporins.
methodsWe reviewed 161 genomes of V. cholerae isolated between 2019 and 2024 from travellers returning to the UK, screening this dataset for resistance to the extended-spectrum cephalosporins encoded by blaPER-7.
resultsWe identified 3/51 V. cholerae O1 ST69 isolates and 1/110 non-O1 isolate belonging to ST555, harbouring blaPER-7 alongside mph(A), encoding azithromycin resistance. Long-read sequencing confirmed that both these genes were on a YemVchMDR1 element, that also possessed an MDR island carrying genes encoding resistance to aminoglycosides, sulphonamides and florfenicol. This element was located on an IncC plasmid in the ST69 O1 isolates but had inserted into the chromosome of the non-O1 isolate.
conclusionsPublic health institutions have the ability and responsibility to monitor the burden and spread of highly drug-resistant V. cholerae via passive surveillance, informing clinical guidance, empirical treatment and travel advice.
