Cluster Life CycleLytic
Lysogeny NotesThe phage appears lytic at first glance due to almost exclusively producing completely clear plaques on the bacterial law. However, bacterial growth was found to be present in the centers of plaques for certain clinical isolates of P. acnes analyzed from the results of the host range assay and select plates of MINI and MIDI phage lysates. This bacteria was isolated and tested for lysogenic character. Patch testing suggested the phage was indeed lysogenic, and spot testing suggested that the phage was also immune to superinfection in certain clinical isolates upon reinfection with the same phage (Aquarius). PCR was conducted using specific primers which correspond to genomic ends that are likely capable of circularization, which yielded a characteristic ~0.75 kb (~735 bp) band on the gel, suggesting the capacity of Aquarius for undergoing a pseudolysogenic life cycle.
