An outbreak of lymphogranuloma venereum has been detected following reports of the disease in Europe. “From October 2004 to the end of April 2007, 492 cases of lymphogranuloma venereum were diagnosed in the UK. These cases were predominantly in men who have sex with men and many of the patients were also infected with other STIs, particularly with HIV,” says Professor Catherine Ison from the Health Protection Agency Centre for Infections in London.
Until recently doctors saw very few cases of lymphogranuloma venereum in the UK, Europe and other developed countries. The disease is caused by certain strains of the bacterium Chlamydia trachomatis and required new diagnostic tests, that had previously not been available in the UK, before the outbreak could be detected.
Bacteria evolve all the time, and the new sexually transmitted bacterial diseases including this new variant of Chlamydia trachomatis are presenting fresh challenges in diagnosis to medical support teams.
“Microbiologists want to be more proactive in helping patients with STIs,” says Professor Ison. “We have made advances in diagnosis by using molecular tests such as the nucleic acid amplification tests (NAATs) which give us a more accurate results, faster turnaround times and can be used with non-invasive samples. These tests can be used for screening in specialised sexual health care clinics and in primary care. However they need to be carefully validated before use.”
“While the advances in technology have enabled progress in many areas, the new tests should only be used by experts who understand their advantages and disadvantages and can interpret the test results properly”, says Professor Ison. “We are very concerned that some of the new tests are being offered for sale over the internet, for home use, when they should really only be used in clinics”.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment...
Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
