Bacteria inside red mites could be targeted to control poultry pests

05.09.2007
Bacteria which live symbiotically inside the blood-sucking pests called red poultry mites could be a new and effective target to prevent the spread of Salmonella and similar pathogens in chickens, turkeys and other table birds, according to scientists speaking today (Wednesday 5 September 2007) at the Society for General Microbiology’s 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 September 2007.

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.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

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...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

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...

Im Focus: Microprocessors based on a layer of just three atoms

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...
