Am I correct that T7 will only infect and lyse E.coli B strains so you
can't get plaques on K12 strains? We occasionally do 20 litres or so
'cos we use the DNA as one phage DNA in many for screening for new RE's.
Even with that amount we have never had contamination problems. It also
won't form a lysogen as it is totally lytic like all T-odd phages (and

The problem with being on the cutting edge is that you occasionally get 
sliced from time to time....
