Malaria makes relapsing fever more serious

08.05.2009
Malaria and the Borrelia infection relapsing fever are diseases with similar symptoms that can occur simultaneously.

In such cases, the malaria is moderated while the relapsing fever becomes more serious. This is shown in a new doctoral dissertation by Jenny Lundqvist at Umeå University in Sweden.

Malaria is a common disease in tropical Africa, causing between 1.5 and 2.7 million deaths each year. As a rule, only the clinical symptoms are used for quick diagnosis in order to prescribe the proper treatment. However, this type of presumptive diagnosis is problematic, as there are other diseases that have the same symptoms, such as relapsing fever (an infection caused by bacteria of the Borrelia genus).

How the patient is affect by this was previously unknown, and, to study the phenomenon, an animal model was created for this type of double infection. It turned out that when both diseases occur at the same time the malaria is much milder whereas the Borrelia infection in turn is more serious, indeed, fatal. This is because the immune defense focuses on the malaria infection, which means that the relapsing fever can grow unhampered. Mice with double infection develop severe anemia and serious internal damage, above all in the spleen, which is important for the immune defense. Malaria can also revive a dormant Borrelia in the brain and cause the relapsing fever to flare up anew.

This new knowledge about double infection by malaria and relapsing fever will be important for the diagnosis and treatment of both diseases, especially in Africa.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
