Mini journal club: staged phage attack of a humanizes microbiome of mouse

Doing another mini journal club here.  Just got notified of this paper through some automated Google Scholar searches: Gnotobiotic mouse model of phage–bacterial host dynamics in the human gut

Full citation: Reyes, A., Wu, M., McNulty, N. P., Rohwer, F. L., & Gordon, J. I. (2013). Gnotobiotic mouse model of phage–bacterial host dynamics in the human gut. Proceedings of the National Academy of Sciences, 201319470.

The paper seems pretty fascinating at first glance. Basically they built on the Jeff Gordon germ free mouse model and introduced a defined set of cultured microbes that came from humans.  And then they stages a phage attack on the system and monitored the response of the community to the phage attack.

Figure 1 from Reyes et al.

They (of course) also did a control - in this case with heat killed phage.  And they compared what happened to the live phage.  I love this concept as they are able to control the microbial community and then test dynamics of how specific phage affect that community inside a living host.  Very cool.
