Attack strategy of salmonella bacteria

A recent study by scientists from the Imperial Institute of Technology (UK) showed that Salmonella bacteria when infecting target cells applied a three-step strategy very seriously.

Salmonella.

In the latest issue of the American Journal of Science report, the scientists said Salmonella when infecting target cells will follow a three-step sequence.

First, forming a sharp needle on the surface to build up contact with the target cell; secondly, some specialized proteins will pass this pointed needle to move to the target cell, destroy the cell membrane of the target cell and create a third "hole;" micro cell Salmonella will pass this 'hole' to release toxic proteins into target cells.

Professor David Holden, in charge of the research team, said the Salmonella activity process could ensure success rates of infection.

The disease caused by Salmonella is a disease usually transmitted through contaminated food. Clinical manifestations of patients are headache, abdominal pain, vomiting, diarrhea and fever.

Scientists hope that, after studying Salmonella's mechanism of targeting target cells, it may help to research drugs or vaccines that treat Salmonella.
