Antibiotic antibiotic therapy. The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics. Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. For example, antibacterial selection for strains having previously acquired antibacterial-resistance genes was demonstrated in 1943 by the Luria–Delbrück experiment. Antibiotics such as penicillin and erythromycin, which used to have a high efficacy against many bacterial species and strains, have become less effective, due to the increased resistance of many bacterial strains. Resistance may take the form
Antibiotic Action Antibiotic Action Antibiotic Action is a UK-based initiative that works to raise global awareness about antibiotic resistance, and is funded by the British Society for Antimicrobial Chemotherapy (BSAC), a UK registered charity. Antibiotic Action seeks to inform and educate people from various backgrounds, ranging from politicians to healthcare professionals to the public, about the need for discovery, research, and development of new treatments for bacterial infections to combat antibiotic resistance. It also aims to strengthen and enhance academic-industrial partnerships by bringing together communities that need antibiotics with academia, health-care professionals, and pharmaceutical companies to address the challenges facing antibiotic research,
