Figure 5From: Inducible Siphoviruses in superficial and deep tissue isolates of Propionibacterium acnesP. acnes bacteriophages host-range groups. The host-range for phages isolated from P. acnes was determined by using a bacterial overlay of different P. acnes isolates and adding phages. Four bacterial isolates (KPA171202, AD7, AS1 and AS5) were used to divide the phages into different host-range groups. Phages in host-range group PA I could infect and lyse all four isolates, PA II all except for KPA171202, PA III (AD7, AS1), PA IV (AD7), PA V (AD7, AS5), PA VI (PAD7, PAS42), PA VII (AS1, AS5), PA VIII (AS1, AS5, KPA171202) and PA IX could not infect and lyse any of the isolates used.Back to article page
