Abstract:
The chromosomally mediated penicillin and tetracycline resistance associated genes include penA, ponA, penB, penC, mtr and tet in Neisseria gonorrhoeae. The mosaic-like structure of penicillin-binding protein 2 gene (penA) is associated with reduced susceptibility to cephalosporin. Double gyrA mutations plus a parC mutation play an important role in the development of high-level fluoroquinolone resistance in N. gonorrhoeae. A single-step mutation in spe gene leads to the high-level spectinomycin resistance. The mutations at multiple loci are associated with multidrug-resistant phenotype. | |||||||||||||||||||||||||||||||||||||||||||||||||||
