Their product is a commercial analysis kit, sold under the brand name “Bruce-ladder,” and was developed in collaboration with Ingenasa, a Madrid-based business dedicated to applied biotechnology in the areas of animal and human health and food safety.
Bruce-ladder permits the identification and differentiation of the microorganism via the amplification of sequences of specific genes using the PCR (polymerase chain reaction) technique. In order to develop this product, these microbiologists of the School of Sciences analyzed the complete sequences of the genomes of various distinct species of Brucella, which permitted them to design a system capable of differentiating them in a single test, and in less than 24 hours.
The novelty of this techniques derives from the fact that is able to distinguish all the known species of Brucella, including vaccine lines and the isolated species present in marine mammals.
A more rapid and safe analysis
"Up to now, differentiation of Brucella was only performed in central laboratories, by means of complicated biochemical and serological techniques, handling the bacteria themselves, which involved a risk for the laboratory personnel. Now, with this new molecular test, the bacteria samples can be analyzed in a simpler and more rapid manner, without having to handle the bacteria directly", as the microbiologists of the University of Navarra explained. The kit has been tested by various leading laboratories in France, Belgium and Portugal, and has been approved by the National Brucellosis Reference Center, in Granada.
Brucellosis is an infectious disease which affects both livestock and persons. According to the World Health Organization, brucellosis is part of a group of diseases, which also includes rabies and anthrax, which are considered “forgotten” diseases, and are strongly related to poverty. The incidence of brucellosis is very high in Africa, Asia, the Middle East and Latin America, and it is a factor in the lack of economic progress and development in these areas of the world. This new kit will aid in its diagnosis, and will permit epidemiological studies which will help to control and eventually eradicate the disease.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
