Staphylococcal Phages Adapt to New Hosts by Extensive Attachment Site Variability.
Article in mBio, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Bacterial pathogens commonly carry prophages that express virulence factors, and human strains of Staphylococcus aureus carry Sa3int phages, which promote immune evasion. Recently, however, these phages have been found in livestock-associated, methicillin-resistant S. aureus (LA-MRSA). This is surprising, as LA-MRSA strains contain a mutated primary bacterial integration site, which likely explains why the rare integration events that do occur mostly happen at alternative locations. Using deep sequencing, we show that after initial integration at secondary sites, Sa3int phages adapt through nucleotide changes in their attachment sequences to increase homology with alternative bacterial attachment sites. Importantly, this homology significantly enhances integrations in new rounds of infections. We propose that promiscuity of the phage-encoded tyrosine recombinase is responsible for establishment of Sa3int phages in LA-MRSA. Our results demonstrate that phages can adopt extensive population heterogeneity, leading to establishment in strains lacking bona fide integration sites. Ultimately, their presence may increase virulence and zoonotic potential of pathogens with major implications for human health.
