You’re most likely aware of antibiotic resistance, unless you’ve completely avoided television and periodicals for the last few years. It’s been in the news quite often, as it appears to be a growing problem that has physicians, scientists, and hospitals concerned. As the term implies, antibiotic resistance refers to bacteria that somehow manage to escape harm from antibiotics that worked against them in the past.
What are bacteria?
Bacteria have been around for billions of years and are the oldest life forms on the planet. Although bacteria are microscopic one-cell organisms, if combined, they would have more mass than all the animals and plants on Earth put together. That’s pretty mind boggling! What they lack in size, they make up for in sheer number. It’s estimated that there are some five nonillion sharing the globe with us. By the way, a nonillion is the number 1 followed by thirty zeros, according to a mathematics website.
Antibiotics and harmful bacteria
Many bacteria are good, but it’s usually the bad ones that we pay attention to. When we get a bacterial infection, we’re often prescribed an antibiotic. Antibiotics work by either killing the bacteria, stopping their growth, or both.
How does antibiotic resistance happen?
Antibiotic resistance sometimes happens when a person with a bacterial infection doesn’t take their antibiotics as directed. When and if the antibiotics are discontinued before the bacteria are no longer a threat, the strongest cells survive to wreak more havoc. Also, after being exposed to certain antibiotics for a long time, bacteria can sometimes adapt for survival. When that happens, we get antibiotic resistance.
