Using 3D printing technique to create biofilms

Researchers at the University of Rochester, and Delft University of Technology in the Netherlands recently developed a 3D printing technique to engineer and study biofilms—three-dimensional communities of microorganisms, such as bacteria, that adhere to surfaces. The research provides important information for creating synthetic materials and in developing drugs to fight the negative effects of…

Article • Where are the infectiologists?

‘The hygiene plan is nothing but a fig leaf’

Nosocomial infections cause more deaths than traffic accidents – a stunning discovery made in a recent German study. Worse: infectious diseases long thought eradicated in Europe, such as measles, tuberculosis (TB) and, more recently, syphilis, are also implicated. The increasing number of patients places an additional financial burden on healthcare. But – and this might be the good news –…

Systems biology of antibiotics

Bacteria have fascinating properties. They adapt excellently to their respective environment, and they existed long before humans. Their toughness has led to the fact that bacteria have successfully spread all over the world for three billion years – even in places where humans could not survive, for example in the hottest springs and in the coldest places on earth. However, they were only…

Antibacterial chemicals in consumer products backfire

Grocery store aisles are stocked with products that promise to kill bacteria. People snap up those items to protect themselves from the germs that make them sick. However, new research from Washington University in St. Louis finds that a chemical that is supposed to kill bacteria is actually making them stronger and more capable of surviving antibiotic treatment. The study, available online in…

WHO: High levels of antibiotic resistance found worldwide

WHO’s first release of surveillance data on antibiotic resistance reveals high levels of resistance to a number of serious bacterial infections in both high- and low-income countries. WHO’s new Global Antimicrobial Surveillance System (GLASS) reveals widespread occurrence of antibiotic resistance among 500 000 people with suspected bacterial infections across 22 countries.

Interview • Multiresistant pathogens

'Antibiotics don’t generate large profits'

During our European Hospital interview with specialist in microbiology, virology and infection epidemiology Beniam Ghebremedhin MD, from the University Hospital Wuppertal, spoke about the impact of migration on infections, and ways to tackle the problem of multiresistant pathogens. ‘There is a lack of specialists in infectious diseases, for direct patient care on hospital wards as well as in…

A strain of multidrug-resistant Escherichia coli is on the rise

Antibiotic resistant bacteria lead to infections that are difficult to treat, particularly in hospitals. Multidrug-resistant Escherichia coli bacteria which have developed special enzymes that render antibiotics ineffective frequently cause such infections. DZIF scientists from Gießen University examined these bacteria more precisely and discovered a strain of Escherichia coli that has been…

Hand washing: in hot or cold water?

‘The literature on hand washing, while extensive, often contains conflicting data, and key variables are only superficially studied, or not studied at all. Some hand washing recommendations are made without scientific support, and agreement between recommendations is limited,’ explained Professor Donald W Schaffner at Rutgers University, New Jersey, USA, who has led a team of researchers to…

Carbapenem resistant strains

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…

Last resort antibiotic under treat

Data presented at the European Congress of Clinical Microbiology and Infectious Diseases diseases has highlighted how a recently-discovered mechanism could mean one of the last-resort antibiotics is under threat. Evidence put before ECCMID suggested the genetic mechanism allowing bacteria to develop and transfer resistance to colistin has been present in several countries around the world –…

Antibiotic resistance mechanism continues to spread

Researchers presented findings on the prevalence of the mcr-1 gene, a transferable genetic mechanism of antimicrobial-resistance to colistin - the last resort antibiotic in a number of circumstances. At a session dedicated to late-breaking abstracts on colistin resistance, researchers presented evidence on the prevalence of the gene in bacteria (including Enterobacteriaceae such as Escherichia…

Well organised against EHEC

In late May, a particularly aggressive and new strain of enterohaemorrhagic Escherichia coli (EHEC) posed an enormous challenge for northern German hospitals. In Hamburg, the focus of the epidemic, more than 1,000 people fell ill, about 180 of them seriously, after getting into contact with the bacterium. Report: Meike Lerner

Healthy gut flora could prevent obesity

Poor gut flora is believed to trigger obesity. In the same way, healthy gut flora could reduce the risk. This has shown to be the case in tests on rats. Daily intake of a lactic acid bacteria, which has been given the name Lactobacillus plantarum HEAL19, appears to be able to prevent obesity and reduce the body’s low-level inflammation.

ESBL: A greater danger than MRSA?

In hospitals, MRSA is considered Public Enemy Nr 1, and the increase in nosocomial infections, worldwide, has drawn universal attention to this ‘superbug’. However, Staphylococcus aureus is not alone – other pathogens are proving their resistance to antibiotics, in the last decade, gram-negative enterobacteria, which form the enzyme extended-spectrum beta-lactimases (ESBL), have joined the…

Insulin without patent protection

A new method to produce insulin cheaply has been developed by researchers at the Helmholtz-Centre for Infection Research (HZI) in Braunschweig, in a German-Indo collaboration. The group’s results are published in the open access online research magazine Microbial Cell Factories. The data is freely accessible by anyone and is not subject to patent law.

Surgical site infections

Post-operative wound infection occurs after an estimated 17% of surgical operations – sometimes with devastating consequences for the patient. The list of preventive measures is manifold and long. However, one strategy is increasingly moving into the spotlight: the use of antibacterial coated sutures. Ethicon Products is at the cutting edge in this field. Sandra Rasche, head of this Business…

New ingredient in paints kills superbugs

Scientists found out that particles of titanium dioxide, which is e.g. contained in the white lines at tennis courts, can kill bacteria and destroy dirt when activated by fluorescent light. Added in paints, the nanotitanium can kill superbugs on all surfaces in hospitals.

Bacteria die on stainless steel

To establish which materials allow pathogens to survived best, micro-organisms such as bacteria living in wet and dry environments, pathogenic fungi and the bacterium Escherichia coli, have been studied during comparative tests undertaken at the Hygiene Institute of the University of Leipzig.
