1 · What the graph read from it

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.

2 · The registry

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

backgroundEnterococcus faecium and Enterococcus faecalis are opportunistic pathogens that form an increasing concern for hospital-acquired infections due to their natural and acquired antimicrobial resistance (AMR). Although phage therapy has gained global interest as a response to emerging AMR, Enterococcus remains an understudied target for phage therapy. In this context, we aimed to isolate Enterococcus-specific phages and study their in vitro infection efficacy when combined into cocktails, in the presence of antibiotics and human serum and against bacterial biofilms.

resultsWe isolated one E. faecium-phage fHoEfm07, that did not resemble any known phage genera and four E. faecalis-phages belonging to Saphexavirus (fHoEfa01 and fHoEfa06) and Efquatrovirus (fHoEfa03 and fHoEfa04) genera. The phages from the genus Saphexavirus and fHoEfm07 were suitable for therapeutic applications based on their genome characterization; however, the phages belonging to the Efquatrovirus genus contained a potential AMR-related gene. In vitro studies indicated that interactions between phages, antibiotics, and human serum depended on the specific phage-host pairing or antibiotic concentration. Moreover, only phage fHoEfa03 reduced the biofilm masses after 3 h and 24 h phage treatment.

conclusionsThis study provides valuable insights into the potential of Enterococcus phages in conditions mimicking phage therapy. The characterization of novel phages, assessment of their therapeutic suitability, and exploration of synergistic treatment strategies contribute to the foundational knowledge required to advance phage therapy.
