Penicillinase plasmid Australia type in Neisseria gonorrhoeae isolated in Poland
Bibliographic record
Abstract
Abstract Purpose Neisseria gonorrhoeae is an etiological agent of gonorrhea which remains a major public health problem the mechanisms that determine resistance to drugs of the beta-lactam class, which are recommended for the treatment of gonorrhea, are currently the most important problem in its treatment. Chromosomal mutations are responsible for resistance to ceftriaxone and cefepime. The possibility of mutations in the gene encoding beta-lactamase ( bla TEM ) in the penicillinase plasmid may also turn out to be a serious threat. Methods The occurrence of resistance encoded on penicillinase plasmid has been investigated. For this purpose, the susceptibility of bacteria was determined and the gene for resistance to beta-lactams as well as the plasmids themselves was typed. Results Of the 333 strains tested, 21 (6.3%) had the beta-lactamase gene and produced penicillinase. Two of the beta-lactamase: TEM-1 and TEM-135 occurred among the tested strains of N. gonorrhoeae . Most of the known penicillinase plasmid types of N. gonorrhoeae were demonstrated: the Asian, the African, the Toronto/Rio plasmids and Australian variants. Conclusions In the first 3 years, TEM-1 beta-lactamases dominated in N. gonorrhoeae , which were replaced by TEM-135 in the following years of the study. Not all molecular methods are capable of varying the types of penicillinase plasmids. A particularly noteworthy observation is the fact that the Australia-type of penicillinase plasmid (3270 bp) was identified for the first time in Europe, and the second time in the world.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
