Remarks
Originally described as short tailed.
Guanine partially replaced by unknown base; DNA contains nonidentified sugar.
Infects log-phase cells only.
Adsorbs well, forms large, moderately turbid plaques from which lysogens can be isolated. Pre-adsorption is not required for plating.
Phage inoculum for double-layer agar 15 000 PFU, yield 10^11 PFU.
Multiplies on *S. marcescens* CV (σ)
