Abstract

Transfer of conjugative transposon Tn1545 from Enterococcus faecalis to Listeria monocytogenes was studied in vitro and in vivo. Tn1545 transferred following filter mating at a frequency of 2.5 x 10(-7) transconjugants per donor colony. A 20-fold increase in transfer frequency was observed when matings were performed in the presence of a subinhibitory concentration of tetracycline. The frequency of in vivo transfer of Tn1545, expressed as the number of transconjugants per donor cell extracted from the intestines of the gnotobiotic mice after 35 days of experiment, was 1.1 x 10(-8). Presence of a low concentration of tetracycline in the drinking water increased this frequency 10-fold.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
