Complete genomic sequence of the Vibrio alginolyticus bacteriophage Vp670 and characterization of the lysis-related genes, cwlQ and holA.

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
backgroundBiocontrol of bacterial pathogens by bacteriophages (phages) represents a promising strategy. Vibrio alginolyticus, a gram-negative bacterium, is a notorious pathogen responsible for the loss of economically important farmed marine animals. To date, few V. alginolyticus phages have been successfully isolated, and only three complete genome sequences of them have been released. The limited available phage resources and poor genomic data hamper research on V. alginolyticus phages and their applications for the biocontrol of V. alginolyticus.
resultsWe isolated a phage, Vp670, against the V. alginolyticus strain E06333 and obtained its full genomic sequence. It contains 43,121 nucleotides with a GC content of 43.4%, and codes for 49 predicted open reading frames. Observation by electron microscope combined with phylogenetic analysis of DNA polymerase indicates that Vp670 belongs to the subfamily Autographivirinae in the family Podoviridae. orf3 (designated holA) and orf8 (designated cwlQ) are predicted to encode a holin (HolA) and an endolysin (CwlQ), respectively. Expression of holA alone or coexpression of holA and cwlQ from within arrested the growth of Escherichia coli and V. alginolyticus while the expression of cwlQ alone had no effect on the growth of them. Further observation by transmission electron microscopy revealed that the expression of holA vanished the outer membrane and caused the release of cellular contents of V. alginolyticus and the coexpression of holA and cwlQ directly burst the cells and caused a more drastic release of cellular contents. Expression of cwlQ alone in V. alginolyticus did not cause cytomorphological changes.
conclusionsPhage Vp670 is a V. alginolyticus phage belonging to the family of Podoviridae. The genome of Vp670 contains a two-component lysis module, which is comprised of holA and cwlQ. holA is predicted to encode for the holin protein, HolA, and cwlQ is predicted to encode for the endolysin protein, CwlQ. Both holA and cwlQ likely play important roles during the release of phage progeny.
