When it comes to automation, clinical microbiology has for many years lagged behind other laboratory disciplines. Robotics and computer processing revolutionized chemistry and hematology instruments decades ago. Meanwhile, clinical microbiologists continue to open specimen containers by hand and grow bacteria using methods familiar to microbiology’s founding fathers from the 19th century.
Virology is fast emerging as a key discipline within modern healthcare against a backdrop of a shifting global demographic and the impact of climate change.
The increasing numbers of bacteria resistant to the newer generations of antibiotics is a public health problem on a global scale. Bacteria have an extraordinary capacity for adaptation, mutating permanently to overcome the action of our increasingly impotent antimicrobial armamentarium. A situation further aggravated by the use of the powerful ‘large spectrum’ antibiotics, creating further…

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).

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 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…
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…

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…
