Antibiotic resistance in gonorrhea mechanism for beta-lactam resistance. There have been over 200 beta-lactamases described and some of them are antibiotic specific. TEM-1 is a penicillinase specific for penicillins. This enzyme will bind to the beta-lactam ring which is a structural characteristic for beta-lactams and hydrolyze the ring. This renders the antibiotic inactive. The spread of the penicillinase resistance was much faster compared to the chromosomal-mediated resistance mechanisms. The plasmids containing TEM-1 could be passed from bacterium to bacterium via conjugation Quinolones are a class of synthetic antibiotics that inhibit DNA replication, recombination, and repair by interacting with the bacterial DNA gyrase and/or topoisomerase
Quinolone antibiotic 4-quinolones, are gemifloxacin (Factive) and trovafloxacin (Trovan) (removed from clinical use). In development. Quinolones have been widely used in animal husbandry, and several agents have veterinary-specific applications. Quinolone antibiotic A quinolone antibiotic is any member of a large group of broad-spectrum bactericides that share a bicyclic core structure related to the compound 4-quinolone. They are used in human and veterinary medicine to treat bacterial infections, as well as in animal husbandry. Nearly all quinolone antibiotics in use are fluoroquinolones, which contain a fluorine atom in their chemical structure and are effective against both Gram-negative and Gram-positive bacteria. One example is
