Bacteria’s DNA fingerprint suggests it could be spreading via food distribution
This article discusses the spread of Clostridium difficile, a microbe that causes gut infections. C. difficile is an important topic of discussion because it appears to be transmitted through food, resistant in some people, seen in a lot of hospitalized patients, and it can be dangerous. To track the source of this bacterium, scientists have been using DNA fingerprinting. Dr. David Eyre, the researcher of this topic, has been promoting washing hands to prevent the spread however, he thinks it is beyond this because there are different strains appearing together in different countries.
This topic ties into a couple of our lectures. We’ve discussed resistance, the human microbiome, and washing hands (soap) as being a way to kill bacteria.
I find this topic important especially since Clostridium difficile appears to be widespread and affecting certain countries. DNA fingerprinting is a great method for finding the source of a spread and I think if scientists continue to practice this kind of research we could get to a place where we can stop a disease before it begins.
My question for you is: Will this be good enough? What other ways can we prevent the spread of an infection?
