Antibiotic resistance happens when an antibiotic loses its ability to effectively control or kill bacteria. The bacteria become "resistant" and continue to grow because the antibiotic being administered has no ability to kill them. The World Health Organization, the U.S. Centers for Disease Control ...
What makes bacteria antibiotic resistant?Bacterial IntelligenceMany antibiotics are very specific as to the species of bacteria it wants to target and kill.

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...
What is bacterial vaginosis? Antibiotic resistance This colorized image (a scanning-electron micrograph) shows four spherical methicillin-resistant Staphylococcus aureus (MRSA) bacteria (purple) in the process of being “ingested” by a human neutrophil white blood cell (blue).

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 ...
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...

It's kind of scary to think of a world filled with antibiotic resistant bacteria. I guess we just have to hope that there are people out there who are able to come up with new antibiotics as fast as the old ones stop working.
