Loss of low-level antibiotic resistance in Neisseria gonorrhoeae due to env mutations.

abstract：:Kasugamycin-resistant mutants of Bacillus subtilis were isolated and classified into two groups, one of which had resistance to kasugamycin in in vitro protein synthesis and mapped in the ribosomal region. The other group had no resistance to kasugamycin in in vitro protein synthesis and had weak cross-resistance to g...
