Investigation of CRISPR-Independent Phage Resistance Mechanisms Reveals a Role for FtsH in Phage Adsorption to Streptococcus thermophilus.
Article in Journal of bacteriology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Prokaryotes are under constant pressure from phage infection and thus have evolved multiple means of defense or evasion. While CRISPR-Cas constitutes a robust immune system and appears to be the predominant means of survival for Streptococcus thermophilus when facing lytic phage infection, other forms of phage resistance coexist in this species. Here, we show that S. thermophilus strains with deleted CRISPR-Cas loci can still give rise to phage-resistant clones following lytic phage challenge. Notably, non-CRISPR phage-resistant survivors had multiple mutations which would truncate or recode a membrane-anchored host protease, FtsH. Phage adsorption was dramatically reduced in FtsH mutants, implicating this protein in phage attachment. Phages were isolated which could bypass FtsH-based resistance through mutations predicted to alter tape measure protein translation. Together, these results identify key components in phage propagation that are subject to mutation in the molecular arms race between phage and host cell.
