Abstract

The nucleotide sequence of the tetracycline resistance gene encoded by the self-transferable plasmid pIP1433 in Campylobacter coli BM2509 has been determined. The resistance gene, tetO, was located in an open reading frame of 1917 bp corresponding to a protein with a calculated Mr of 72 290. The transcriptional and translational signals have been identified. The tetO gene exhibits 76% sequence identity with tetM from Streptococcus and the deduced amino acid sequences are 77% homologous. The substitutions are scattered throughout indicating that the two genes have diverged from a common ancestor. We suggest that tetracycline resistance in Campylobacter is due to acquisition of a gene originating in a Gram-positive bacterium. The distribution of tetO in hundred strains of C. jejuni and C. coli resistant to tetracycline (MIC ≥ 32 μg/ml) and to minocycline (MIC ≥ 4 μg/ml) was studied by dot blot hybridization under high stringency conditions using a 1.4-kb intragenic probe. Homology with tetO was detected in 98 strains isolated from humans and animals in various geographical areas. None of the strains hybridized with tetM under the same conditions. These data indicate that tetO is widespread among Campylobacter spp. probably due to conjugative plasmids.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Tet(O), like other RPPs, seems to have originated in Streptomyces rimosus, which harbors otrA, an RPP determinant.

    “However, Tet(O), like the other RPPs, seems to have originated in the natural producer of oxytetracycline, Streptomyces rimosus , which harbors otrA , an RPP determinant (16, 44, 49).”

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.
