Functional Genomics of Antibiotic Susceptibility in Enterococcus faecalis From Infective Endocarditis.
Article in The Journal of infectious diseases, 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
Enterococcus faecalis is an opportunistic pathogen that causes infective endocarditis. Despite in vitro synergy of the recommended combination ampicillin-ceftriaxone (AC), E faecalis infective endocarditis (EFIE) mortality remains high. We characterized 119 isolates from patients with EFIE in our health system from 2018 to 2023 genomically and phenotypically. Three genetic lineages (ST6, ST40, and ST179) accounted for 41% of all infections. ST6 isolates were less susceptible to ceftriaxone and AC in dual-antibiotic checkerboard assays, but also exhibited decreased survival in dual-antibiotic killing assays using humanized AC exposures. ST6 isolates encoded a known genetic disruption affecting pbp4 as well as mutation of a putative hydrolase called phnP. Functional studies confirmed that both alterations contributed to altered AC susceptibility. Finally, we found that ampicillin plus daptomycin showed robust growth inhibition and killing against EFIE isolates with decreased AC susceptibility. These findings enhance our understanding of EFIE and may guide better therapeutic strategies.
