Abstract
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.

Pathogens 2021; 10:pathogens10101240. [PMID: 34684189 PMCID: PMC8540940 DOI: 10.3390/pathogens10101240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 09/19/2021] [Accepted: 09/23/2021] [Indexed: 11/16/2022] Open
Abstract
Salmonella is one of the major causes of foodborne disease outbreaks globally. Specifically, Salmonella enterica subsp. enterica serovar Enteritidis (S. Enteritidis) is one of the major causes of zoonotic Salmonella infection in humans worldwide. In this study, we present data on antimicrobial resistance (AMR) and plasmid profiles of S. Enteritidis strains isolated from patients, food, and the environment in Siberia and the Far East of Russia obtained during Salmonella monitoring between 1990 and 2017. A total of 345 S. Enteritidis isolates were tested by the disk diffusion method with a set of 15 antibiotics using EUCAST breakpoints v. 10 and by plasmid profile analysis using the alkaline lysis method. The results have shown a substantial decrease in susceptibility to aminoglycosides and quinolones during the study period. No significant differences were found in the susceptibility of strains between regions as well as in the its correlation with different plasmid types of the pathogen. Several S. Enteritidis strains were found to be resistant to ampicillin, kanamycin, tetracycline, chloramphenicol, and cephalosporins. All tested S. Enteritidis strains were susceptible only to imipenem. In this study, we observed a relatively low level of AMR in S. Enteritidis strains isolated in Siberia and the Far East of Russia. Nevertheless, it is important to continue the molecular genetic monitoring and AMR surveillance of S. Enteritidis to track further increases in AMR using conventional phenotypic susceptibility testing and by introducing whole-genome sequencing to identify AMR mechanisms.
