摘要

Two bacteriophages specifically active against to pathogenic strains of the Salmonella genus were isolated. The morphology of phage colonies (size, transparency, and shape of the plaque edge, and halo) and the spectrum of their lytic activity and interaction with microbial cells (adsorption rate, duration of the latency, and reproductive efficiency) were examined. Using genome-wide sequencing, we determined the taxonomic position of bacteriophages and verified the absence of unwanted genes encoding toxins, adhesins, and invasins, as well as pathogenicity islands responsible for antibiotic resistance. In addition, phage stability under different physical conditions and their productivity were studied.
