Antimicrobial resistance and molecular characterization of ESBL-producing Enterobacterales from Parirenyatwa Hospital wastewater in Harare.
Article in JAC-antimicrobial resistance, 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
Background: The hospital environment is a proven hotspot for antimicrobial-resistant bacteria, which may be released through hospital wastewater into the environment and municipal wastewater. The aim of this study was to monitor the occurrence of and perform molecular characterization of MDR ESBL Enterobacterales isolated from Parirenyatwa Hospital wastewater, Harare, Zimbabwe. Methods: This was a cross-sectional study. Enterobacterales from sixty-four 500 mL samples of hospital wastewater from three drainage sites of Parirenyatwa Hospital were isolated. A modified double disc synergy test was used to confirm ESBL Enterobacterales before genotyping with multiplex PCR. Results: The majority of isolates came from the main hospital drainage site. All the isolated Enterobacterales showed MDR. Of the 33 Enterobacterales isolated from hospital wastewater, 8 (24%) were ESBL-producing: 5/8 (63%) Conclusions: MDR ESBL-producing Enterobacterales were identified from Parirenyatwa Hospital wastewater. The MARI greater than 0.2 indicated that these isolates were from a high-risk source of contamination.
