At the same time, we’ve stopped discovering new ones.Still, there’s hope that we can get ahead of the problem.But first, how did we get into this situation?The first widely used antibiotic was penicillin(青霉素),discovered in 1928 by Alexander Fleming.In his 1945 acceptance speech,...
Antibiotics are powerful germ-fighting tools when used carefully and safely. But up to half of all antibiotic use isn’t necessary. Overuse has led to antibacterial resistance. Bacteria adapt over time and become “super bacteria” or “superbugs.” They change so that antibiotics no longer work...
Antibiotics used to treatS. suisinfection are multiple, and they are from different classes, including β-lactams, aminoglycosides (usually combined with β-lactams), amphenicols, and fluoroquinolones. The pattern of antibiotic usage varies between countries, regions, and even farms, which largely infl...
A patient is prescribed 0.5 g of an antibiotic every 12 hours. The antibiotic liquid is labeled 250 mg/5 mL. a. How many mL should be used at each dose? b. How many mg of antibiotic are in each dose? c. How many ug (micromolar solution)...

However, differences in pathophysiology, immunology and PK between species still exist. Mathematical modeling, whereby preclinical data are integrated with human population PK, can facilitate translation of preclinical data to the patient's clinical situation. Moreover, PK/PD modeling and simulations can...

s structure. A structural biologist at the Weizmann Institute of Sciences, Fleishman used a computational approach to predict mutations that increase the protein’s stability. When Newman’s group applied the customized enzyme to populations ofP. aeruginosa, the antibiotic destroyed a larger proportion ...
Methylene Blue is a very popular antibiotic used to treat severe cases of fin damage. The chemical name of this medicine ismethylthioninium chloride. This medication is primarily used to treat conditions that arise due to fungal infection. Thus, for fin damage from bacterial infection, this medic...
University of Washington biologist Carl Bergstrom, PhD, who studies evolution and medicine, said in an interview. “The key point for me is that in antibiotic resistance, the changes happen in people who are on antibiotics,” he said, while antigenic escape by SARS-CoV-2 occurs in people who...
