Probiotics in pigs may reduce Salmonella
Probiotics have shown promise in reducing incidence of
Salmonella (picture) in pigs, say researchers from the UK.
Probiotics, also known as 'good bacteria' naturally occur in the gut of
humans and other animals and are understood to boost immunity and help prevent
bad bacteria from causing illness.
By adding them to feed or food,
the aim is to boost the population of good bacteria in the gut to improve the
Increase food safety
Now, however, it
seems there may be grounds for probiotics to be fed to pigs to reduce incidence
- an idea that could not only open a new sales channel for
suppliers but also increase the safety of food products and decrease salmonella
cases in humans.
Researchers from the UK's Veterinary Laboratories
Agency in Weybridge, Surrey, reported positive results from a 3D model of a pig
gut. Their findings are presented today at the meeting of Society for General
Microbiology in Edinburgh, UK.
Pig gut model
experiment involved a special technique based on NASA space technology that
enabled the researchers to grow pieces of pig gut in a three-dimentional matrix
that replicates the natural environment inside a pig's gut.
model specifically allows us to test the potential benefits of probiotics as
viable alternatives to growth promoters in pigs," said researcher James Collins.
The researchers said that although they have seen benefits from the
probiotics, they have not yet established exactly how
they work to reduce
pathogens and bring about other health benefits. They hope the model will prove
instrumental in shedding light on the mechanism.
