Antibiotic resistance in gonorrhea Antibiotic resistance in gonorrhea The Gonorrhea bacterium Neisseria gonorrhoeae has developed antibiotic resistance to many antibiotics. The bacteria was first identified in 1879, although some Biblical scholars believe that references to the disease can be found as early as Parshat Metzora of the Old Testament. In the 1940s effective treatment with penicillin became available, but by the 1970s resistant strains predominated. Resistance to penicillin has developed through two mechanisms: chromasomally mediated resistance (CMRNG) and penicillinase-mediated resistance (PPNG). CMRNG involves step wise mutation of penA, which codes for the penicillin-binding protein (PBP-2); mtr, which encodes an efflux pump that removes penicillin
Antibiotic resistance in gonorrhea ability of the antibiotic to get into, or stay in the bacterial cell. High level resistance of "N. gonorrhoeae" to tetracyclines was first reported in 1986 with the discovering of the "tetM" determinant. The mechanism of resistance is still unknown. "N. gonorrhoeae" has also shown resistance to the aminoglycoside class of antibiotics. These antibiotics bind to the 16s rRNA of the 30S subunit of the bacterial ribosome, thereby stopping transcription of the bacterial genome. Resistance appears to be acquired through porin-related mechanisms, much like the cephalosporin resistance mechanism. This mechanism would result in the access of the antibiotic to the
