Bring me more genomes

"If the history of public health has until now been embodied by the map—as in British physician John Snow’s famous map, which allowed him to curb the London cholera outbreak of 1854 and to found, in doing so, the modern field of epidemiology—Snitkin was embarking on a new kind of epidemiology: one founded on the phylogenetic tree." Writing for Wired, Carl Zimmer describes how Evan Snitkin and Julie Segre used genome sequencing to halt a bacterial outbreak at the National Institute of Health's Clinical Center. (via The Feature)

That was fascinating — and a little terrifying at the amount of effort the NIH had to bring to bear to squash a bacterial outbreak confined to a single hospital.

The most amazing part of this was that they were able to get plumbers at NIH in building 10 to show up and quickly do plumbing.

A "friend of mine" remembers having a fairly large leak in a steam pipe in lab that was just left for weeks. That "friend" put up signs offering free steam baths and just kept working.

So just looking at the chart of dots (and not knowing what the circles and colors represent - if they represent anything, or are just something Wired came up with) how did patient 1 manage to be the source of three other infections, all of which had different polymorphisms between themselves but none had the four represented by red dots in patient 1? Doesn't that kind of suggest a stepping stone of some sort between 1 and the other 3?

Or am I overthinking an example infographic is a piece of scientific reporting?

Patient 1 was a host to more than one strain of KPC. Patient 3 was infected by the strain from patient 1's throat, which is not represented by the top line of the chart. The first KPC strain sequenced from patient 1 is shown at the top of chart (the second strain is last).

Great read, thanks for posting.

Great story.

Great story. I have one question that maybe the biotech-savvy people here could answer. It's great that they can sequence all the different strains. Why can't they do anything with this knowledge, to come up with a drug or something that kills the bacteria? Is it the amount of testing that would have to be done before such a drug could be used?

That is a great story. Carl Zimmer is one of the better science writers.

Pedant's note: National Institute of Health's Clinical Center

A lot of people get this wrong. It's the National Institutes of Health. There are many.

Oh, and great post.
