We can not find a strain of E. coli pop 154 that has transduced receptor for bacteriophage Lambda (LamB) from Shigella Sonnei. Therefore we would like to get non-toxic strain of Shigella sonnei, from where we could isolate targeted protein.
Thank you in advance for answer!
Warm regards
Hello, unfortunately Shigella boydii, dysenteriae, flexneri, sonnei all are BSL 2.

Have considered contacting Alex Evilevitch ([email protected])?
His group from Carnegie Mellon University recently published a paper (Ionic Switch Controls the DNA State in Phage λ) using that strain. They also published in PNAS two years ago (Solid-to-fluid–like DNA transition in viruses facilitates infection).
There are avirulent strains of Shigella sonnei, but they are all still classified as BSL-2 for safety reasons.
