Vaccinating chickens could prevent food-borne illness

26.03.2012
A vaccine could be developed to prevent Campylobacter being carried in chickens. This approach could drastically cut the number of cases of food poisoning, saving the UK economy millions each year, says an American scientist presenting his work at the Society for General Microbiology's Spring Conference in Dublin.

Food-borne illness costs the UK an estimated £2 billion each year. Campylobacter is the leading cause of food-borne illness and is responsible for about 30% of cases in the UK. Campylobacter jejuniwas responsible for more than 371,000 estimated cases in England and Wales in 2009, resulting in more than 17,500 hospitalizations and 88 deaths.

Campylobacter jejuni is found in the gut of many animals, including chickens. If Campylobacter-contaminated poultry is not prepared and cooked properly, the micro-organism can be transmitted to humans where it may cause severe gastrointestinal disease.

Scientists at Washington State University are studying the maternal antibodies that are passed from hens to their chicks. "These antibodies protect chicks from becoming colonized by Campylobacter in the first week of life," explained Professor Michael Konkel who is leading the research. "Our group has now identified the bacterial molecules that these antibodies attack, which has given us a starting point for a vaccine against Campylobacter," he said. "We have already found that chickens injected with these specific molecules – found on the surface of Campylobacter jejuni – produce antibodies against the bacterium. This response partially protects them from colonization."

A vaccine could be a powerful weapon to help control food-borne illness. "Preventing contamination of poultry at slaughter has not been effective at reducing illness in humans. It has been shown that about 65% of chickens on retail sale in the UK are contaminated with Campylobacter," explained Professor Konkel. "Ideally, the best way to prevent contamination is to stop chickens on the farm from becoming colonized with this microorganism in the first place, which could be achieved by vaccination. Our goal within the next 6 months is to test a vaccine for chickens that will reduce Campylobacter colonization levels. There's still a long way to go, but I'm confident our lab and others are moving in the right direction."

Controlling food-borne illness through vaccination would have a significant impact both in the UK and globally. "A safe food supply is central to human health. If we can decrease the load of human pathogens in food animals, then we can reduce human illness. A 1% reduction in the number of cases of food-borne illness would save the UK around £20 million per year. In developing countries, where people and food animals often share the same environment, diseased animals also pose a direct public health risk; vaccination would help mitigate this risk," said Professor Konkel.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
