Disinfect water its important but is it enough?

Millions of Americans get sick and antibiotics are not a solution for the infections and many of these individuals die. The disinfectants used to kill bacteria or at least to prevent it from growing does not remove the genes that encode for the specific traits that make the bacteria resistant to antibiotics. Even though it is not proven that this is occurring at the moment, researchers want to be aware. A group of people from the University of Washington realized an experiment involving current water and waste water. It consisted in figuring out whether disinfecting water have an effect in antibiotic resistance genes in bacterial DNA. The results showed that qPCR analyses substituents for ARG deactivation. This result could be a rough prediction of actual deactivation levels. In order to provide more information about how this applies to ARGs and other bacterial species, additional work needs to be done. DNA itself is not harmful but it needs to be taken into consideration the effects it could have once it spreads in the environment such as having unwanted traits.

Bacteria are getting hard to kill with antibiotics

Many of us believe that when are buying a water bottle from the store, we are consuming clean water. This is definitely not true in all the cases, as mentioned above different disinfectants can be used to kill bacteria. This does not mean that this water is free from genes that protect bacteria from antibiotics.
