Abstract

Sparling, Philip F. (Communicable Disease Center, Atlanta, Ga.). Genetic transformation of Neisseria gonorrhoeae to streptomycin resistance. J. Bacteriol. 92:1364-1371. 1966.-Eight strains of Neisseria gonorrhoeae were transformed to streptomycin resistance by deoxyribonucleic acid (DNA) extracted from a streptomycin-resistant strain of N. gonorrhoeae. In all strains, competence was greatest in the naturally occurring, virulent clonal types 1 and 2, which gave transformation frequencies up to 1%. Clonal types 3 and 4, which arise on laboratory transfer and are avirulent, gave maximal transformation frequencies of 0.00005%. Competence was maximal in lag and early log phases of growth, but was maintained throughout the growth cycle. A complex broth was required for the physiological expression of competence. The kinetics of DNA uptake, dose-response curve of DNA versus transformants, time required for phenotypic expression, and other features were similar to those in other bacterial transformation systems.

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.
