Morphological and cultural characteristics of Staphylococcus phage PSK. (A) PSK lytic activity was screened by spotting filter-sterilized enriched sewage over the surface soft LB overlay agar seeded with S. aureus SK1. (B) Purified plaques were obtained by replating individual plaques at least five times. (C) TEM imaging was used for morphological analysis of PSK at 100Â nm scale bar
