[1] Microbiology: Gutless worm’s inmates get an identity check

DOI: 10.1038/nature05912

Researchers have analysed the genetic makeup of an entire community of bacteria that live inside an unusual marine worm. Their findings, to be published online this week by Nature, illuminate the pros and cons of this symbiotic relationship and provide a basis for understanding the natural bacterial communities that co-occur within other more complex hosts.

Edward M. Rubin and colleagues used shotgun sequencing and metabolic pathway reconstruction to learn more about the symbiotic microbial community that lives under the skin of the marine worm, Olavius algarvensis. They found four different bacteria that not only provide nutrition for their host, but also remove and recycle the worm’s waste products. This helps explain how the worm lives without mouth-, gut- and kidney-like organs.

[2] Quantum teleportation with increased capacity

DOI: 10.1038/nphys417

The successful teleportation of the combined quantum state of two photons is reported in the October issue of Nature Physics. This is the first time this has been achieved for a composite system, and the approach could enable new ways to harness quantum effects for communication and computation purposes.

A quantum-mechanical system is characterized by a set of properties that can exist in certain possible states. For example, one property of a photon is polarization, whose state can be horizontal, vertical or a mixture of the two. Quantum teleportation transfers the state — in this case of the polarization — of one object to another, which can be an arbitrary distance away; teleportation does not transfer energy or matter.

Teleportation of quantum states involving more than one particle, as now shown by Qiang Zhang and colleagues, is required for a number of protocols for large-scale quantum communication and computation. These promise secure information exchange and the ability to solve certain tasks faster than any classical computer. The authors’ experiment lasted several days, but with further improvements the scheme might become of more practical value.

[3] Overcoming bacterial virulence

DOI: 10.1038/ni1386

An effective way to vaccinate against infection by the plague bacterium Yersinia pestis in mice is reported in a study to be published in the October issue of Nature Immunology. This organism has been a scourge of humans for hundreds of years.

Egil Lien and colleagues have taken advantage of the fact that bacteria like Y. pestis ‘wear a coat’ of protein and fatty sugars. The ‘coats’ of some bacteria normally stimulate mammalian immune cells well, whereas others, such as those of Y. pestis, do not, allowing them to evade or suppress the innate immune response of the host. Lien and colleagues have engineered a Y. pestis strain with a coat that stimulates immune cells in mice, and show that mice can survive infection with this engineered strain. The surviving mice also appear to be protected from subsequent infection with normal, otherwise deadly, Y. pestis. The results suggest that ‘immune stealth’ may be critical for normal Y. pestis to cause serious infection.

The authors propose that their work, which demonstrates that sufficient stimulation of innate immune responses can control infection by a highly virulent pathogen, has broad implications for understanding bacterial virulence in Y. pestis, and also for potential strategies for vaccine production.
