There is a similar study in E. coli from Eric Cascales lab with the same result, no fitness cost for T6SS. I agree it is not what it could be expected but it is consistent so far. Congratulations for this work 👏🏼👏🏼👏🏼

Absolutely! His group’s paper is really cool, and it’s great to see a consensus emerging. I only didn’t mention it in this post due to space limitations. Highlighted it in my Twitter post this am tho!
