Probiotic good bugs may control gut infections

Probiotics, the friendly bacteria beloved of yoghurt advertisers, may be an effective substitute for growth promoting antibiotics in pigs, giving us safer pork products, 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.

Scientists from the UK’s Veterinary Laboratories Agency in Weybridge, Surrey have shown that probiotics – the good bacteria taken by millions of people worldwide – can reduce the disease-causing Salmonella bacteria which infect people and pigs.

“Salmonella is responsible for thousands of food poisoning cases each year with many of the cases originating from infected pork products. Recently the European Union banned the use of antibiotics in animal feed. Antibiotics were being regularly used as growth promoters to make pigs put on weight and protect them from diseases”, says James Collins from the Veterinary Laboratories Agency.

“The EU ban is part of the effort to reduce the emergence of new antibiotic resistant bacteria, particularly as many disease-causing and antibiotic-resistant bacteria such as MRSA and clostridia are now so common”, says James Collins.

The scientists have also managed to advance the use of alternatives in animal testing by developing a technique based on NASA space technology, which allowed them to grow small pieces of pig gut in a 3-dimensional matrix which mimics the natural environment in a pig’s gut.

“The 3D model specifically allows us to test the potential health benefits of probiotics as viable alternatives to growth promoters in pigs”, says James Collins. “This model is an essential first step as an alternative to the use of animals in scientific research, and means that we did not need to do the work in live pigs”.

The work by the Surrey team will contribute to reducing the number of pigs carrying Salmonella, and so cut its general spread in the environment. This in turn is expected to reduce the number of Salmonella related food poisoning cases reported every year.

The scientists have not yet discovered exactly how the probiotics work, but they hope that their new model will uncover the mechanism behind the way robiotics reduce pathogens in the gut and confer other health benefits.

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
