Great work Kiny. Thanks for your posts. I always feel smarter after reading them :)

Two questions:

Do AIEC bacteria respond to antibiotics?
How do we, as potentially vulnerable people, reduce our exposure to them? (Are they commonly caught through food poisoning?)

Yes, they respond to antibiotics like cipro. Although they gain resistance fast. On the flip side, antibiotics might also enable colonisation of AIEC because of changes in the microbiome.

It's not established how you get exposed to them afaik, some domestic animals like cats and dogs carry them and some people without crohn's disease carry AIEC too. It's the tipping point where AIEC strains are invasive and start to enter tissue and invade macrophages of people with crohn's disease who tend to have innate immunodeficiences, where the problems begin.
I guess the triple antibiotics may help with resistance like combination therapy in AIDS. If it's one in a million for each new bacterium (likely in bacteria) that resistance will evolve then using three should give a million cubed.

I guess different gene variants of Crohn's may have different tipping points and immune weaknesses.

I remember having a pet bird with psittacosis which is caused by an intracellular bacteria. They had to treat that for a couple of months with doxycycline and even afterwards couldn't give me any reassurance that the infection was gone.

Here in the UK I'm always surprised by our general practitioners referring to the disease as an auto-immune one. The gastroenterologists seem to have accepted that it probably isn't!
