Researchers at Bristol University recently presented
new findings regarding Campylobacter
contamination in poultry populations. Professor Tom Humphrey
from the University’s Department
of Clinical Veterinary Science, led a new study showing that
Campylobacter levels increase in the gut of chickens and other farm
animals when they are transported. According to a Bristol University
Research in many
countries has shown that after transport, levels of bacteria like
Campylobacter are higher in the gut of food animals than on the farm.
Work at Bristol has demonstrated that this may be associated with the
release of the stress hormone noradrenalin. This hormone makes
Campylobacter grow more quickly, become highly motile and invasive,
leading to an increase in its ability to cause disease - its virulence.
A further finding in
the studies at Bristol is that Campylobacter can interact with other
organisms in the gut of food animals. When this happens it can become
even more infective. The results of this study provide vital
information to enable the control of infection in the production
environment, making chicken safer and decreasing cases of food
Infection caused by
Campylobacter bacteria is called campylobacteriosis and is usually
caused by consuming unpasteurized
milk, raw or undercooked meat or poultry, or other contaminated
foods and water, and contact with feces from infected animals.
Campylobacter infection, which usually occur within 2 to 10 days after
the bacteria are ingested, include fever, abdominal cramps, and
diarrhea (often bloody). In some cases, physicians prescribe
antibiotics when diarrhea is severe. The illness can last about a week.
include meningitis, urinary tract infections, and possibly reactive
arthritis (rare and almost always short-term), and rarely, Guillain-Barre syndrome, an
unusual type of paralysis. While most people who contract
campylobacteriosis recover completely within 2 to 5 days, some
Campylobacter infections can be fatal, resulting in an estimated 124
deaths each year.
