WEDNESDAY, Aug. 3 (HealthDay News) -- The identification of a
new multidrug-resistant strain of salmonella shows the importance
of public health surveillance in a global food system, French
Their analysis of national surveillance systems in the United
States, Denmark, France, England and Wales revealed the emergence
S. Kentucky strain of salmonella, which has a high level of
resistance to ciprofloxacin, a common treatment for severe
This strain infected 489 patients in France, England and Wales,
and Denmark between 2000 and 2008. The first infections were
acquired mainly in Egypt between 2002 and 2005. Since 2006,
infections have also been acquired in various parts of Africa and
the Middle East.
About 10 percent of the European patients said they hadn't
traveled to any of these areas, which suggests that their
infections may have resulted from eating contaminated imported
foods or through contact with infected people, said the Pasteur
The investigators found that chickens and turkeys from Ethiopia,
Morocco and Nigeria carried the
S. Kentucky strain, an indication that poultry may be an
important source of infection.
The study is published online in the
Journal of Infectious Diseases.
"We hope that this publication might stir awareness among national and international health, food and agricultural authorities so that they take the necessary measures to control and stop the dissemination of this strain before it spreads globally, as did another multidrug-resistant strain of salmonella, Typhimurium DT104, starting in the 1990s," study co-leader Simon Le Hello said in a journal news release.
