These mechanisms, occurring alone, are able to increase azithromycin MIC to 0.5mg/L, and thus are not able to condition azithromycin resistance. The G1407 genogroup, in particular the ST1407 sequence type, is currently dominant in most European countries. Clinical Significance: However, if symptoms persist, the patient should be evaluated using N gonorrhoeae culture (with or without simultaneous NAAT), and any gonococci isolated should be tested for antimicrobial susceptibility.

They are very rare or non-existent in the currently isolated strains [24]. An example of new inhibitors of bacterial topoisomerase, that could be used in the treatment of gonorrhoea are fluoroquinolones: delafloxacin, sitafloxacin or two drugs in clinical investigations, zoliflodacin and gepotidacin. account history.

Multidrug-resistant, Lefebvre B, Martin I, Demczuk W, Deshaies L, Michaud S, Labb AC, et al. Methodology Transcription-Mediated Amplification (TMA) Sixty-four patterns of the PBP2 protein are described (85576 amino acid region). In addition to mutations in the PBP2 encoding genes, the increase in penicillin MIC may also be conditioned by mutations in the penC gene (alternative gene name: pilQ), encoding PilQ secretin [59]. There is also a problem with spectinomycin accessibility in many European countries and in North America. This combination was found in more than 40% of N. gonorrhoeae strains resistant to fluoroquinolones and conditioned ciprofloxacin MIC from 4 to 32mg/L [96].
