Salmonella phages SenALZ1 and SenASZ3, two novel phages infecting Salmonella enterica, were isolated and analyzed. The genomes of these two phages consist of 154,811 and 157,630 base pairs (bp), with G+C contents of 44.56% and 44.74%, respectively. Fifty-nine of 199 open reading frames (ORFs) in the SenALZ1 genome, and 60 of the 204 in the SenASZ3 genome show similarity to reference sequences in the NCBI nr database that encode putative phage proteins with predicted functions. Based on the results of transmission electron microscopy (TEM) examination, complete genome sequence alignment, phylogenetic analysis, and gene annotation, we propose that these two phages are representative isolates of two new species of the genus Cba120virus, subfamily Cvivirinae, family Ackermannviridae.
