Antibiotic last line of defence" antibiotic. Per "The ICU Book" "The first rule of antibiotics is try not to use them, and the second rule is try not to use too many of them." Inappropriate antibiotic treatment and overuse of antibiotics have contributed to the emergence of antibiotic-resistant bacteria. Self-prescribing of antibiotics is an example of misuse. Many antibiotics are frequently prescribed to treat symptoms or diseases that do not respond to antibiotics or that are likely to resolve without treatment. Also, incorrect or suboptimal antibiotics are prescribed for certain bacterial infections. The overuse of antibiotics, like penicillin and erythromycin, has
Antibiotic resistance in gonorrhea the "parC" gene which encodes for the topoisomerase IV. Topoisomerase IV acts similarly to DNA gyrase and is involved in unwinding DNA for replication. Ceftriaxone and cefixime are third generation cephalosporins and are often used as treatments for "N. gonorrhoeae infections". The cephalosporins are part of a larger beta-lactam family of antibiotics. The newly discovered H041 strain of "N. gonorrhoeae", originally isolated from a commercial sex worker in Japan, was shown to be resistant to this antibiotic. The possible mechanisms of resistance to this antibiotic are as follows: Tetracyclines are a class of antibiotics that inhibit protein synthesis by binding
