Paris, 9 sep (EFE).-salmonella can cause foodborne illness in humans not only by consumption of eggs and meat, but also through fruit and verdudas contaminated with the bacteria, according to a study released today in Paris.
It’s the scientific confirmation that the bacterium salmonella enterica can trigger salmonella, the most common food poisoning, since you now know how that infects the fruit and vegetables.
Thus indicated the French Centre for scientific research (CNRS in its French acronym), which refers to the study conducted by scientists at the University of Evry (France), Giessen (Germany) and Vienna.
The authors of the study – published this week in the American publication “PLos ONE” – indicate that salmonella agrees to the plants on the surface of plant cells, entering through the pores of the leaves.
Salmonella inhibits the immune systems of the plants according to a mechanism similar to get access to the human.
The report’s authors claim that plants contaminated by salmonella are very infectious in human cells, and it has also found in cells of mice.
In humans, the salmonella bacteria injected with an appendix, in a similar way to a DART, a cocktail of proteins that block immune defenses and favour the proliferation of the bacteria in the body
Scientists who participated in the study have observed the same phenomenon in plants and they have succeeded in demonstrating, according to the CNRS, salmonella polluting plants is very infectious in humans and mice, “which represents a new challenge in terms of food safety and health surveillance”.
However, neither human nor plants are defenceless against salmonella, recalled the CNRS, since both have developed forms of detection of bacterial attack that activate their immune systems respective.
Annually, it is estimated that some 100 million people are infected with salmonella, which is the leading cause of gastroenteritis and typhoid fever, he recalled the Agency Gallen.
Until not long ago, it was thought that the infection in humans occurred only by ingestion of contaminated products of only animal origin (meat, eggs and milk), but in the last ten years has detected an increase in infected persons after consuming vegetables, according to the CNRS. EFE
