- rpoS396(Am) was reported to be present in W1485 by Visick and Clarke, J.Bact. 179:4158. It is not cited as the CGSC 5024 culture, so we are not certain of its presence here.
- This strain does not carry a suppressor mutation and it does not have Tn1000 inserted into the chromosome, as do some derivatives of this strain which have been called simply ``W1485."
