Paper Information

A total of 307 samples were analyzed, resulting in a total of 162 virus-like particles (VLPs) analyzed. The LP was performed to identify Salmonella strains susceptible to phage infection, including the most frequent serovars: Dublin, Enteritidis, and Javiana. From the VLPs, nine phages were selected for genomic comparison. These phages represent three morphotypes: siphoviruses, myoviruses, and podoviruses, originating from different geographic and productive sites.

Salmonella represents a significant risk to both public and animal health. Although Salmonella strains have not been isolated from cattle livestock, Salmonella phages have been successfully identified.

Our study was conducted through (i) investigating the presence of Salmonella strains and Salmonella phages in three study areas, (ii) phenotypic screening by lytic profile (LP); (iii) selecting nine phages for sequencing; and (iv) genomic comparison to evaluate their relative diversity.

This study enhances the understanding of the presence and diversity of Salmonella phages in cattle livestock, even in the absence of Salmonella strains.
