A team of international researchers has discovered a new Ebola-like virus – Lloviu virus -- in bats from northern Spain. Lloviu virus is the first known filovirus native to Europe, they report in a study published in the journal PLOS Pathogens on Octobr 20th.
The study was a collaboration among scientists at the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health, the Instituto de Salud Carlos III (ISCIII) in Spain, Roche Life Sciences, Centro de Investigación Príncipe Felipe, Grupo Asturiano para el Estudio y Conservación de los Murciélagos, Consejo Suerior de Investigaciones Científicas and the Complutense University in Spain.
Filoviruses, which include well-known viruses like Ebola and Marburg, are among the deadliest pathogens in humans and non-human primates, and are generally found in East Africa and the Philippines. The findings thus expand the natural geographical distribution of filoviruses.
"The study is an opportunity to advance the knowledge of filoviruses' natural cycle," said Ana Negredo, one of the first authors of the study.
Scientists at ISCIII analyzed lung, liver, spleen, throat, brain and rectal samples from 34 bats found in caves in Asturias and Cantabria, Spain, following bat die-offs in France, Spain and Portugal in 2002 affecting mainly one bat species.
They screened these samples for a wide range of viruses using the polymerase chain reaction, a molecular technique that allows scientists to amplify genetic material, and. detected a filovirus. Filoviruses include ebolaviruses and marburgviruses, two viruses associated with severe disease in humans and other primates..
CII scientists used high-throughput sequencing to characterize the virus' genome. When they compared it to other well-known filovirus genomes, they found that Lloviu virus represents a class of viruses distantly related to all ebolaviruses and that it may have diverged from ebolaviruses about 68,000 years ago.
"The detection of this novel filovirus in Spain is intriguing because it is completely outside of its previously described range. We need to ascertain whether other filoviruses native to Europe exist, and more importantly, if and how it causes disease," said Gustavo Palacios, the other first author of the study.
Filoviruses typically do not make bats sick, but because the team of researchers only detected Lloviu virus in bats that had died and whose tissues showed signs of an immune response, they think Lloviu may be a cause for concern. They also did not detect Lloviu virus in samples of almost 1,300 healthy bats.
Bats have important roles in plant pollination, spreading plant seeds and controlling insect populations, and pathogens that attack bat populations could have dramatic ecological and health-related consequences.
"The Lloviu virus discovery highlights how much we still need to learn about the world of emerging infectious diseases and the importance of global collaboration and the One Health initiative in addressing the challenge," said CII Director Dr. Ian Lipkin.
This research was funded by the Defense Threat Reduction Agency, USAID PREDICT, the RICET Network on Tropical Diseases and the Ministerio de Educación y Ciencia in Spain.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
