New tick-borne disease threatens primarily immune suppressed persons

27.05.2014

A newly discovered tick-borne bacterium known as "Candidatus Neoehrlichia mikurensis" has been implicated in six cases of disease in Sweden. A new international study led by the Sahlgrenska Academy has shown that this bacterium is primarily a risk for people who are already sick and who are receiving immunosuppressive drugs.

The Candidatus Neoehrlichia mikurensis bacterium, known in the medical world by its short name Neoehrlichia, was discovered and described for the first time in a scientific article in 2010.

The bacterium, which is spread by rodents and ticks mainly in Asia and Europe, including Sweden, has been found in 19 cases worldwide, six of them in Sweden.

Eleven cases closely examined

Scientists and doctors from Germany, Switzerland, The Czech Republic and Sweden have examined 11 of these cases more closely, in an international research project led by the Sahlgrenska Academy. The study has shown that it is primarily people who are already sick who run the greatest risk of becoming infected by the bacterium.

"Those who run the greatest risk are generally over the age of 50 years, suffer either from a haematological disease or a rheumatic disease, and are currently undergoing immunosuppressive treatment with, for example, chemotherapy or cortisone," says Christine Wennerås, scientist at the Sahlgrenska Academy.

Difficult to detect

No figures are available for how common the tick-borne infection, neoehrlichiosis is in humans. This is mainly due to the infection being difficult to detect.

"The bacterium cannot be grown in culture, and this means that it is not picked up in routine diagnostic procedures. Furthermore, the symptoms are deceptive: several patients, for example, have been affected by blood clots in the leg or the blood vessels in the head, and this has not been coupled to an infectious cause. Other typical symptom such as fever, muscle pain and joint pain can be caused also by the patient's underlying disease," says Christine Wennerås.

"We know very little about how the infection affects otherwise healthy people who are not taking immunosuppressive drugs."

Once neoehrlichiosis has been diagnosed, the patients recover completely after treatment with antibiotics.

The study Infections with the tick-borne bacterium "Candidatus Neoehrlichia mikurensis" mimic non-infectious conditions in patients with B cell malignancies or autoimmune diseases has been e-published ahead of print on March 18, and will appear in Clinical Infectious Diseases.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
