Economic losses inside the European Union caused by the red poultry mite are now running at roughly €130 million or nearly £90 million every year. The mite causes blood spotting on eggs, making them unfit for sale. In severe cases the infested birds can become badly anaemic and fall ill, or get infections caused by bacteria and viruses which can be passed on to people, giving them dangerous illnesses.
“With the recent changes in regulations brought on by new threats like bird ‘flu, coupled with a growing and widespread resistance to the chemicals we use to fight poultry mites, called acaricides, we urgently need to develop new approaches to combat these pests”, says Dr Olivier Sparagano from Newcastle University, UK.
“If somehow we could develop a method to destabilise the symbiotic bacteria that we have discovered living inside the mites, therefore removing the beneficial effect, we could develop a new control method for the chicken red mite”, says Dr Sparagano.
If the scientists are successful then the use of acaricide chemicals could be cut, which in turn would reduce the harmful effect they have on the environment and cut down cases of skin rashes and dermatitis in poultry farmers, smallholders and meat packers. Some traces of acaricides have even been found in eggs intended for human consumption.
“The bacteria are obviously very important to the mites. A new control method based on attacking the symbiotic bacteria inside the mites’ bodies would also create economic benefits through higher egg quality and production, and fewer diseases transmitted by these parasitic mites. It would also lead to better welfare for the birds”, says Dr Sparagano.
Red poultry mites are a direct threat to economically valuable birds, suspected of passing on diseases like Newcastle Disease. But they have also been shown to be part of a wider chain transmitting diseases to people and other animals such as the food poisoning bacteria Salmonella, and equine encephalitis in horses.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
