Widespread antibiotic use in human medicine and livestock production has helped fuel the growth of antibiotic-resistant bacteria (aka superbugs). Additionally, in the developing world, antibiotics are often sold without prescription and the lack of clean water and good sanitation helps superbugs spread ...
As predicted almost 70 years ago by the man who discovered the first antibiotic, drug resistance is upon us. How do antibiotics work? Although there are a number of different types of antibiotic they all work in one of two ways: A bactericidal antibiotic kills the bacteria. Penicillin is a...
Manuel Razo-Mejia:When I expose bacteria to antibiotics, they’re going to become resistant, which is very bad because we haven’t discovered a new antibiotic in the last 30 years. Growing up back in Mexico, you did...
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. The word antibiotic means “against life.” Any drug that kills germs in your body is technically an antibiotic, but most people...

The global emergence of multidrug-resistant Gram-negative bacteria is a growing threat to antibiotic therapy. The chromosomally encoded drug efflux mechanisms that are ubiquitous in these bacteria greatly contribute to antibiotic resista... Li, Xian-Zhi,P Plésiat,H Nikaido - 《Clinical Microbiology ...

Antibiotics are used to treat infections caused by bacteria. Bacteria are microscopic organisms, some of which may cause illness. The word bacteria is the plural of bacterium. Such illnesses as syphilis, tuberculosis, salmonella, and some forms of meningitis are caused by bacteria. Some bacteria ...
What makes bacteria antibiotic resistant?Bacterial IntelligenceMany antibiotics are very specific as to the species of bacteria it wants to target and kill. When developing resistance, this particular bacteria can change parts of itself so it is unrecognizable to the very antibiotic designed to destroy...
