Summary:
A gene editing technique called a Gene Drive which is based on the well known CRISPR technique has been shown to be able to completely eliminate a mosquito population in the lab.
Connections:
We have been learning about the various techniques used through history to prevent diseases, from antibiotics to vaccines, this represents another potential tool capable of having a similar impact.
Critical Analysis:
The prevention of deadly diseases has been and continues to be one of the greatest goals of the study of microbiology and malaria is currently one of the most deadly infections still at large in the world with 219 million cases of malaria in 2017, up from 217 million cases in 2016 despite incredible continued efforts to prevent its’ spread. A commonly targeted element of the disease is the delivery method, mosquitoes. However while previous efforts have failed to slow the spread, this technique has demonstrated the potential to not just slow them but to precisely and completely eliminate an entire species.
Question:
What other populations can this be applied to? For instance, would it be appropriate to eliminate the populations of rats devastating island bird populations?

says:the scary part about taking out population is that you are never 100 % sure what will take there place.

says:Well hopefully when it comes to malaria the answer will be “nothing”.
Elora S Swan
says:This is actually really cool, there are so many places that have such bad spread of sickness due to mosquitos. Malaria is one of the worst. I have seen bad cases of Malaria, and hopefully taking out the mosquito population would not have too bad of an affect on the environment.
