Evaluation of plasmid content and tetracycline resistance conjugative transfer in Enterococcus italicus strains of dairy origin.
Article in Current microbiology, 2009. 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
Five Enterococcus italicus strains harbouring tet genes responsible for the tetracycline resistance were subjected to plasmid profile determination studies. For four strains tested the profiles showed between three and six plasmid bands, the size of which ranged between 1.6 and 18.5 kb. Southern hybridization experiments associated tetS and tetK genes with chromosomal DNA in all strains and tetM gene with plasmids of around the same size (18.5 kb) in two of the tested strains. The ability of the new species to transfer tetM gene was studied by transfer experiments with the tetracycline-susceptible recipient strains E. faecalis JH2-2 and OG1RF; mobilization experiments were performed with E. faecalis JH 2-2 harbouring the conjugative plasmid pIP501as helper plasmid. The results obtained show that the new enterococcal species was able to acquire antibiotic resistance by conjugation, but not to transfer its plasmids to other bacteria. Further PCR and hybridization experiments carried out to assess the presence of mobilization sequences also suggest that the tetM plasmid from E. italicus is a non-mobilizable plasmid.
