Figure 3From: Inducible Siphoviruses in superficial and deep tissue isolates of Propionibacterium acnesP. acnes bacteriophages classified as Siphoviruses. Phages were negatively stained with 0.75% uranyl formate. All phages were classified as Siphoviruses based on their morphology. No difference in morphology could be observed between the different phages. Several of the phages have empty heads and adhere to bacterial cell debris.Back to article page
