Call for urgent action to improve CDI management

CDI Europe, the European Hospital and Healthcare Federation (HOPE) and MEP Karin Kadenbach hosted an event at the European Parliament to highlight the urgent action needed to address the current issues relating to the management of healthcare-acquired infections (HAIs) and Clostridium difficile infection (CDI).

Diagnosing gastrointestinal infections

The human gut literally teems with microorganisms from at least 1,000 different species that are increasingly considered to be a valuable resource for the prediction, aetiology and prognosis of disease. Due to continual contact with the environment, primarily via food, the gut is susceptible to infection when a virus, parasite or bacterium enters and disrupts normal gut microbiota (or flora).

POCT accelerates diagnosis of STDs

Trichomonias, with an estimated 187 million cases, and Chlamydia with around 100 million, are the most prevalent sexually transmitted diseases (STDs), according to the World Health Organisation (WHO). There are approximately 36 million cases each of gonorrhoea and syphilis. HIV1/2 cases are around 34 million. Report: Cynthia Keen

Cutting the risks of injury and contamination

Austrian firm Greiner Bio-One is presenting products for the pre-analysis and diagnostics industry at this year’s Medica. Vacuette safety products have been developed to minimise this risk of injuries from contaminated puncture devices – a significant safety hazard to healthcare workers, the firm underlines.

Molecular diagnoses will become routine

Molecular diagnostics is one of the most important technological advances in clinical diagnostics, seeing the €3.6 billion market grow 10% in constant currency (CC) in 2010 and predicted continual growth well above the diagnostic industry rates. The recipe for success in this field lies in three critical components: core technology, automation and menu. During our interview with Marc Meyer, the…

System identifies more pathogens and antimicrobial resistances than any other

By integrating all necessary pre-analytical and analytical steps into one solution, the recently CE-marked Unyvero system, which is now commercially available in Europe, provides pathogen identification and antibiotic resistance marker information without needing expert staff and a sophisticated infrastructure, its manufacturer Curetis reports. Of even greater interest is its range of targets.

A new strain of MRSA discovered

While researching bovine mastitis (an S. aureus infection that occurs in the cows’ udders), researchers led by Dr Mark Holmes at the University of Cambridge, UK, identified a new strain of methicillin-resistant Staphylococcus aureus (MRSA) which occurs both in human and dairy cow populations.

The 3rd Annual General Meeting of the Austrian Society for Laboratory Medicine and Clinical Chemistry

Different tests bring different results, and results of the same types of test vary from laboratory to laboratory. "In the case of test procedures for autoimmune diseases there are incredible discrepancies," confirmed Professor Manfred Herold, head of the Laboratory for Rheumatism at the University Clinic for Internal Medicine One, Innsbruck. The reason: "There are no standards for…

MRSA

Effective screening can kill several birds with one stone

The MRSA problem has been ignored almost stoically in many European countries for the past 20 years. Thus the number of resistant Staphylococci cases exploded from 1% in 1990 around 25% in 2010. However, the recognition that an infection can result in additional hospital costs of up to €10,000 has led to a change in thinking. The Netherlands, for example, declared war on MRSA with ‘search and…

C. difficile - Molecular scientists design a very quick cheap test

A small team of researchers at Barts and London School of Medicine and Dentistry, in London, has developed a rapid, cheap and effective kit to test for the presence of Clostridium difficile. And, they report that the new kit costs as little as 50 pence to £1 per test and can deliver results in under an hour, compared to commercial kits that cost up to £25 and in some cases take significantly…

New weapons enter the un-ending war against MRSA

A decade ago the battle against hospital-acquired MRSA (methicillin-resistant Staphylococcus aureus bacterial strain) infections appeared to be lost, or at least without end. However, today, we see very important science-to-business achievements in this field. Report: Rostislav Kuklik

The value and development of PCR tests

Whereas, in the past, the diagnoses of infectious diseases focused on antibody detection, more recently laboratories aim to identify the agent itself, using the invaluable PCR (polymerase chain reaction) test. We asked Prof Beatus Ofenloch-Hähnle, head of Reagent and System Development Immunology, at Roche Professional Diagnostics, and Benjamin Lilienfeld, Global Product Manager for Infectious…

40 years of MEDICA

When we organised the first Diagnostic Week in Karlsruhe, in 1969, no one could have known that this event would one day turn into the annual highlight in the world of medicine, reflected Dr Wolfgang Albath, laboratory medicine pioneer and one of the founding fathers of MEDICA the world`s largest medical trade show. Initially planned as a moving exhibition, the show has been based in…

LightCycler MRSA Advanced Test cheats time

How the PCR-Test works The MRSA bacterium contains an additional 'mobile gene cassette' (SCCmec cassette) in its genetic makeup, which contains the so-called mecA gene. All beta-Lactam antibiotics such as Methicillin are therefore no longer effective. The LightCycler MRSA Advanced Test facilitates the detection of all five known SCCmec types within 85 to 100 minutes. This test principle is based…

Revolutionary invention

When Leo Baekeland invented the world's first true man-made plastic in 1907, his diary entry stated that he believed that "this invention will prove important in the future." This was definitely an understatement, since man-made plastics have revolutionised life for us all, especially in the field of drug discovery with major advances in PCR and QPCR techniques undertaken using plastic…
