Very interesting who is frequening the New York subway system (and I assume the findings wouldn't be very different elsewhere...

What surprised me most was not the sheer number of microorganisms found in New York's
subway system and public parks but the discovery that 48% of the DNA recovered from
urban surfaces doesn't match any known organism.

The post that was quoted here has been removedThe research group took swaps from different surfaces in the New York subway system and tried to identify everything that lived in that swaps.
They were able to find out that a lot of pathogenic bacteria live there. For example the Pest bacterium.
They also found that they didn't know the DNA from about half the cells. This is quite common in those swaps. There was an interesting paper on the bacterial fauna in human armpits...but I digress. Attempts to cultivate the new found lifeforms were not succesful.

48% od the DNA found is not from any recognisable known earth type creature
People theorize you were sent from Kolob because your parents didn't want you. Now you go around wearing tights and calling yourself Pooperman. Your favorite is elephant dung.

We are immersed in an ocean of micro-organisms, and even within our own bodies, there are more bacterial cells than human cells (by a factor of 10:1). Micro-organisms surround us and live inside us. Evolutionarily speaking, humans are not the supreme achievement they think themselves to be--bacteria are winning hands down. We are parasites on them: they can live without us but we cannot live without them.

If enough DNA changes hands in one generation, think about how much different the DNA will look like in a thousand generations which is not that much time in the world of Bacteria.

The post that was quoted here has been removedThis is the summary offered by the authors of the report:
The panoply of microorganisms and other species
present in our environment influence human health
and disease, especially in cities, but have not been
profiled with metagenomics at a city-wide scale. We
sequenced DNA from surfaces across the entire
New York City (NYC) subway system, the Gowanus
Canal, and public parks. Nearly half of the DNA
(48 percent) does not match any known organism;
identified organisms spanned 1,688 bacterial, viral,
archaeal, and eukaryotic taxa, which were enriched
for harmless genera associated with skin (e.g.,Acinetobacter).
Predicted ancestry of human DNA left on subway surfaces
can recapitulate U.S. Census demographic
data, and bacterial signatures can reveal a station’s
history, such as marine-associated bacteria in a
hurricane-flooded station. Some evidence of pathogens
was found (Bacillus anthracis), but a lack of reported
cases in NYC suggests that the pathogens represent
a normal, urban microbiome. This baseline metagenomic
map of NYC could help long-term disease surveillance,
bioterrorism threat mitigation, and health
management in the built environment of cities.
