Bacteriophage P2 was first isolated by G. Bertani from the Lisbonne and Carrère strain of E. coli in 1951. [3] Since that time, a large number of P2-like prophages (e.g. 186, HP1, HK239, and WΦ) have been isolated that shared characters such as host range, serological relatedness and inability to recombine with phage λ, and they seemed to be quite common in E. coli populations as about 30% ...
