The 1928 penicillin discovery by Alexander Fleming and its early development reshaped medicine. Florey and Chain's work, Nobel Prize recognition, and the birth of the antibiotic era are highlighted.
Bacterial resistance evolves by natural selection when antibiotics are misused, with innate and acquired resistance spreading via horizontal transmission and resistance genes, posing a health threat.
Monobactams have a single beta-lactam ring and no extra rings, reducing hypersensitivity and offering an alternative in penicillin allergy. They target gram-negative bacteria, including Pseudomonas.
Explore daptomycin, a lipopeptide active against vancomycin-resistant enterococci, given intravenously, with limitations in pulmonary infections and risks of myopathy, rhabdomyolysis, and CPK monitoring, especially with statins.
Explore tetracyclines like doxycycline and minocycline, their broad spectrum against MRSA, gram-positive, gram-negative, and atypical bacteria, acne, Lyme disease, and H. pylori, with safety interactions and contraindications.
Chloramphenicol has broad activity against gram-positive, gram-negative, atypical, and anaerobic bacteria, but its use is limited by serious adverse effects like bone marrow suppression and grey baby syndrome.
Over 90 years ago with the discovery of the first effective and safe antibiotic, everyone expected life is going to be easier, the microbes that once used to threaten us, Cause us lifelong terrible injuries and take the lives of the people we love are finally becoming simply beatable. So Antibiotics indeed saved our lives big time, But our enemies were not any less of smart, they fought us back and didn’t just surrender, and honestly thanks to us, we’ve helped.
The unwise & Unjustifiable use of antibiotics together with the rapid continues genetic mutations bacteria undergoes have led to evolution of resistant strains that continues to Mercilessly destroy our bodies.
Every year, more & more reported cases of infections caused by bacteria found to be resistant to every antibiotic we know are growing everywhere in the world. And more over, no new antibiotics are being developed, The growing question now is: are we heading for a post antibiotics era where common infections and minor injuries that have been treatable for decades are going kill us again?
That’s exactly why this course is being published, I believe more health care professionals have to have a solid understanding of Antibiotics, their chemistry and pharmacology, uses, side effects, and wise treatment regimens for different infections and conditions.
