Misuse or overuse of antibiotics leads to antibiotic resistance.1Once bacteria become resistant to an antibiotic, it can be difficult—and sometimes impossible—to kill them.3They can remain in your body for years and even pass on their antibiotic resistance to other bacteria.4 This article discus...
What is antibiotic resistance? Antibiotic resistance occurs when an antibiotic has lost its ability to effectively control or kill bacterial growth; in other words, the bacteria are "resistant" and continue to multiply in the presence of therapeutic levels of an antibiotic. Why do bacteria become ...
During the past 85 years of antibiotic use, we have learned a great deal about how these ‘miracle’ drugs work. We know the molecular structures and interactions of these drugs and their targets and the effects on the structure, physiology and replication of bacteria. Collectively, we know a...
Today, clinically important bacteria are characterized not only by single drug resistance but also by multiple antibiotic resistance—the legacy of past decades of antimicrobial use and misuse. Drug resistance presents an ever- increasing global public health threat that involves all major microbial ...

The emergence of antibiotic resistance is a product of human behavior. The more antibiotics are used, the more bacteria become resistant to them. For example, antibiotics are often prescribed for viral infections, in which they do not work. Livestock are treated with antibiotics to prevent infectio...
Antibiotic resistanceis the overuse or misuse of antibiotics. The bacteria that caused the initial UTI becomes resistant to the prescribed antibiotics. It makes recurrent UTIs harder to treat and more likely to return. A study byUC Davisshowed that antibiotics were 90% effective in treating simple...
How the Cold War contributed to antibiotic resistanceLearn more about how Cold War medical innovations led to antibiotic-resistant bacteria. See all videos for this article From 1953 to 1957 Cold War tensions relaxed somewhat, largely owing to the death of the longtime Soviet dictatorJoseph Stalin...
Causes of an Onion-Like Vaginal Odor Causes Bacterial vaginosis occurs when the level of "good" bacteria in the vagina suddenly drops. This allows "bad" bacteria to grow excessively. The main "good" bacteria, calledlactobacillus, makes the vagina slightly acidic so that "bad" bacteria can't ...
