Broad-spectrum antibiotic focusing on evidence-based approaches to minimize resistance. In humans: In veterinary medicine, co-amoxiclav, (in small animals); penicillin & streptomycin and oxytetracycline (in farm animals); penicillin and potentiated sulfonamides (in horses). Broad-spectrum antibiotic The term broad-spectrum antibiotic can refer to an antibiotic that acts on the two major bacterial groups, gram-positive and gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria. These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy) or when infection with multiple groups of bacteria is suspected. This is in contrast to
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
