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
Antibiotic use in livestock for not collecting enough information and data on antibiotic use in factory farms. From this, the GAO concluded that the FDA does not have enough information to create effective policy changes regarding antibiotic use. In response, the FDA insisted that more research was being conducted and voluntary efforts within the industry would solve the problem of antibiotic resistance. Few policies exist that limit antibiotic use on factory farms, and some proposed legislation in the US has failed to be adopted. In 2007, two federal bills (S. 549 and H.R. 962) aimed to phase out nontherapeutic antibiotics in U.S. food animal
