Pons, F.W. 1966. Biochem. Z. 346:26-40. (En allemand/In deutsch)

Remarks
May be a virulent mutant of ?(HER313).
Uses the same receptor as ?, forms large, clear plaques containing a few bacterial colonies which are resistant to ? and ?.
Pre-adsorption to indicator bacteria is not required for adsorption.
Plates inoculated with 10^9 bacteria and 15 000 PFU yield 5x10^12 phages (extraction with 5mL saline).
