Researchers Discover How Bacteria Resist Antibiotics in Hospitals; Spotting Infected Patients, Disinfecting Hospitals Key to Curbing Spread of Resistant Bacteria, Experts SayReinberg, Steven
A laboratory study unravels ways antidepressants and other nonantibiotic drugs can contribute to drug resistance
How do antibiotics affect bacterial cell walls?Antibiotics:Antibiotics are active substances that act against bacteria. Such substances are major agents that help to combat bacterial infections in individuals. The most common route of administration is oral. Once in the system, it starts its action ...
If that isn't bad enough, theinformationtransferred also allows the receiving bacteria to pass on the same information to others, meaning that the ability to resistantibioticsand produce toxins rapidly spreads from one bacterium to another. It's a frightening thought. Scientists at Monash University...
How do bacteria resist human antimicrobial peptides? The efficacy of cationic antimicrobial peptides, 'natural antibiotics' of the innate immune system, is limited by a variety of sophisticated microbial mech... A Peschel - 《Trends in Microbiology》...
Some bacteria can naturally resist certain kinds of antibiotics. Others can become resistant if their genes change or they get drug-resistant genes from other bacteria. The longer and more often antibiotics are used, the less effective they are against those bacteria. ...

(抗生素) first became available,farmers used them freely.Now scientists know that the overuse of antibiotics can cultivate drug-resistant bacteria that are dangerous to human health.Among debates over what kinds of restrictions should be put in place.figuring out how antibiotic-r...
Biofilms form when groups of bacteria cover themselves in a sticky mixture of sugars, protein, and DNA. This extracellular matrix glues bacteria to surfaces and serves as a slimy shield, protecting cells in the interior from predators and antibiotics. Conventional drugs become ensnared in the matrix...
bacterial cells in crowded, oxygen-deprived environments access oxygen for energy production, ensuring survival of the cell. The finding could explain how some bacteria, such asPseudomonas aeruginosa(P. aeruginosa), are able to thrive in oxygen-poor environments like biofilms and resist antibiotics. ...
