Borrelia infection from a tick bite just as possible in a city centre park

03.02.2003


The chances of getting a Borrelia infection from a tick bite are no different in a city centre park than they are out in the archipelago. This is one of the recent discoveries of Professor Matti Viljanen and his research team who are looking into how the Borrelia bacteria deceives and manipulates the human immune defence system. The research project under the supervision of Professor Viljanen is part of the Academy of Finland’s Microbes and Man Research Programme.



One in three ticks in the parks in Helsinki, Finland, carry the Borrelia bacteria. Professor Viljanen and his team have also shown that ticks and Borrelia can be transmitted across continents in migratory birds. In birds, the Borrelia bacteria may cause an asymptomatic latent infection. During migration, variations in the bird’s hormone levels will activate the bacteria and cause it to grow in the bird’s blood. This will ensure that the bacteria is transmitted into the ticks living off the bird and improve its prospects of conquering new territory.

The Borrelia bacteria can deceive and manipulate the immune defence system in various different ways. It can mask itself using human proteins and in this way avoid the attacks of the white blood cells that are responsible for first-phase defence. It is also capable of altering the balance of the immune response to its own advantage.


The project is interested to know how the Borrelia bacteria deceives and manipulates the immune defence system at different stages. A further concern is with the question of how the bacteria advances in tissue and how it penetrates the walls of blood vessels. One area of special interest is the activation of a latent infection. The researchers will also be trying to find drugs that can help to restore the balance of the immune system and to cure chronic, rheumatic symptoms. The new information generated will help to produce more effective means for the prevention and treatment of Borrelia infections.

Professor Viljanen from Turku University, Finland, shares responsibility for running the programme with Professor Sven Bergström from Umeå University, Sweden: the Microbes and Man Research Programme is a joint Finnish-Swedish venture

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
