Video Explanation of Basic Mechanisms of Antibiotic Resistance in Bacteria

Posted on Jan 26, 2012 | 0 comments

Here’s a short video that does a good job of explaining how antibiotic resistance is created and then transferred between species of bacteria. As you watch the video remember that almost 80% of antibiotics consumed in North America are given to animals in agriculture and most of them are used at sub-therapeutic doses (doses low enough to only kill part of the population). Additionally, everything we touch is covered in bacteria. Our bodies are covered in bacteria. Our intestines are full of bacteria. There is no escaping them. Thankfully, the vast majority of bacteria are not disease causing. Many are a critical part of the functioning of our digestive system. However, because of the unique bacteria to bacteria DNA transfer mechanisms, resistance that is created in one species on the farm can be transferred to a non-disease causing species. Transported to somewhere else and then the DNA for resistance transferred to a pathogenic species.
