A new virulent phage, SWEP2, infecting the Arthrobacter sp. 5B strain, was isolated from black soil samples in northeastern China. SWEP2 has a latent period of 80 min and a burst size of 45 PFU (evaluated at an MOI of 0.1). Genomic analysis revealed that the 43,398-bp dsDNA genome of phage SWEP2 contains 64 open reading frames (ORFs) and one tRNA gene. Phylogenetic analysis indicated a close relationship between SWEP2 and Arthrobacter phage Liebe, with 82.98% identity and a query coverage of 48%. Based on its distinct phenotypic and genetic characteristics, SWEP2 is identified as a novel Arthrobacter phage.
