Scientists Warn Of Multidrug Resistant Salmonella Strain

Scientists Warn Of Multidrug Resistant Salmonella Strain, The identification of a new strain of multidrug-resistant Salmonella shows the importance of monitoring public health in a global food system, French scientists say.Their analysis of national surveillance systems in the United States, Denmark, France, England and Wales revealed the emergence of the strain of S. Salmonella Kentucky, which has a high level of resistance to ciprofloxacin, a common treatment for severe Salmonella infections.

This strain infected 489 patients in France, England and Wales and in 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 European patients said they had not traveled to any of these areas, suggesting that their infection may have resulted from eating contaminated food imported or through contact with infected people, said researchers at the Pasteur Institute.

The researchers found that chickens and turkeys from Ethiopia, Morocco and Nigeria increased the S. Kentucky strain, an indication that poultry can be an important source of infection.

The study is published online in the Journal of Infectious Diseases.

“We hope that this publication could raise awareness of national and international health, food and agricultural authorities so that they take the necessary measures to control and stop the spread of this strain before it spreads in the world, as did another strain of multidrug-resistant Salmonella Typhimurium DT104, beginning in the 1990s, “study co-leader Simon Le Bonjour said in a news magazine.
