Skin Swap and Contact Sports

Ever wonder how many germs transfer between people on contact? Ever wonder if contact would change the distribution of microbes on your body? A recent paper reveals just that.

Wired magazine states:

After each bout, though, the samples told a different story: the teams’ microbiomes converged, having more species in common. For example, before Emerald City played Silicon Valley, members of the two teams shared 28.2% of their bacterial communities. After the bout, the overlap was up to 32.7%, the team reports today in PeerJ.

The article states:

In these culture-based studies, handshaking, as well as hand-contact with other parts of the body and room surfaces, have been identified as strong vectors of health care service infections, such as with methicillin-resistant Staphylococcus aureus (MRSA) and Klebsiella spp.(Casewell & Phillips, 1977; Davis et al., 2012; Pittet et al., 2006). Given that human contact with surfaces, and especially the skin surfaces of others, has been shown to transfer individual microbial taxa, activities which involve human to human contact could be hypothesized to result in the sharing of skin microbial communities.

How does this make you feel?

Diversity and Variation .. the key to evolution

The genome of the Rock Dove -aka Pigeon, flying rat, etc.- (Columba livia) has been sequenced. In this article, you can see the great diversity of this invasive species that originated in Eurasia and brought over as a food item.

Fancy breeds of pigeon were developed over time since they also served as pets to humans. As with other pets, multiple breeds were developed that preferentially display different variations of traits. Sequencing genomes of other organisms is useful for us to understand the common toolkit that all life forms on this planet share and the effects of carrying specific variations of genes.

The article states:

But Dr Mike Shapiro says the pigeon may lead us to some very useful information about ourselves.

“Just about all animals use the same toolkit of genes to build their bodies and to control similar processes during development,” the University of Utah, Salt Lake City, researcher explained.

“By understanding how these processes work in other animals, we can in turn learn more about normal and abnormal variation in humans as well. If you take the gene we identified, this EphB2 gene – this is a gene that has also been implicated in particular types of cancers. It may also have a role in the progression of Alzheimer’s disease,” he told BBC News.
