Construction of luciferase reporter bacteriophage A511::luxAB for rapid and sensitive detection of viable Listeria cells.
Article in Applied and environmental microbiology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 69 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
Specific transfer and expression of bacterial luciferase genes via bacteriophages provides an efficient way to detect and assay viable host cells. Listeria bacteriophage A511 is a genus-specific, virulent myovirus which infects 95% of Listeria monocytogenes serovar 1/2 and 4 cells. We constructed recombinant derivative A511::luxAB, which carries the gene for a fused Vibrio harveyi LuxAB protein inserted immediately downstream of the major capsid protein gene (cps). Efficient transcription is initiated by the powerful cps promoter at 15 to 20 min postinfection. Site-specific introduction of the luciferase gene into the phage genome was achieved by homologous recombination in infected cells between a plasmid carrying A511 DNA flanking luxAB and phage DNA. Recombinants occurred in the lysate at a frequency of 5 x 10(-4) and were readily identified by the bioluminescent phenotype conferred on newly infected host cells. A511::luxAB can be used to directly detect Listeria cells. Following infection and a 2-h incubation period, numbers as low as 5 x 10(2) to 10(3) cells per ml were detected by using a single-tube luminometer. Extreme sensitivity was achieved by including an enrichment step prior to the lux phage assay; under these conditions less than 1 cell of L. monocytogenes Scott A per g of artificially contaminated salad was clearly identified. The assay is simple, rapid, inexpensive, and easy to perform. Our findings indicate that A511::luxAB is useful for routine screening of foods and environmental samples for Listeria cells.
