Going to 'report death' causes food poisoning

British and American scientists, for the first time, "purge" the trick to evade the E. coli immune system - the culprit of a series of food poisonings worldwide.

When signs of infection are detected, the body produces nitric oxide gas for self-defense. However, according to a sophisticated mechanism, E. coli (Escherichia coli for short) "sniffs" this gas and knows how to disable it. This is an important suggestion for dealing with this bacterium.

Scientists from the Georgia Institute of Technology (USA), in collaboration with John Innes Center (UK), study harmless E. coli strains, but they believe that research results can be applied to many E.coli strains. more poisonous and "brother" salmonella - culprit causing poisoning

series. Salmonella often attacks humans through raw meat, vegetables and poor hygiene, causing diarrhea and cramps. In weak bodies, the consequences can be very serious. Meanwhile, the treatment is often passive because bacteria always learn how to "wriggle" and drug resistance.

In the study, it was found that E. coli bacteria are able to identify and free themselves from the nitric oxide gas that the body produces to fight infection. The reason is that this bacterium possesses a protein called NorR, which controls genes that hold the code of a particular enzyme capable of neutralizing nitric oxide.

"It turns out that NorR protein contains a single iron molecule. The combination of nitric oxide with this iron molecule activates NorR protein," said team member Stephen Spiro. If you can intervene in this mechanism, after a few years, scientists will find antibiotics and more effective treatments.
