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 United States that systematically collects detailed data on antibiotic use in humans and animals. It is not clear which antibiotics are prescribed for which purpose and at what time. Furthermore, the world has no surveillance infrastructure to monitor emerging antibiotic resistance threats. Because of these issues, it is difficult to quantify antibiotic resistance, to regulate antibiotic prescribing practices, and to detect and respond to rising threats. At this time, the most well-documented impact on humans is foodborne gastrointestinal illness. In most cases, these illnesses are mild and do not require antibiotics; though if the infectious bacteria is drug-resistant, they have
