“…All tested S. Enteritidis strains belonged to the top ten plasmid types of the pathogen found to be widespread in the abovementioned regions of Russia: 59 kb (96 strains), 59:2.1 kb (29 strains), 59:3.6:2.1 kb (27 strains), 59:3.9:2.1 kb (19 strains), 59:39:2.1 kb (30 strains), 59:4.5:2.1kb (55 strains), 59:45 kb (28 strains), 59:45:2.1 kb (11 strains), 59:45:3.4 kb (28 strains), and 59:6.7 kb (22 strains) [ 6 ]. The antibiotic susceptibility patterns of S. Enteritidis strains were studied in the context of the plasmid profile.…”

“…Long-term monitoring showed that the S. Enteritidis population in Siberia and the Far East of Russia is highly heterogeneous but mostly limited to the top ten plasmid types of the pathogen: 59 kb, 59:2.1 kb, 59:3.6:2.1 kb, 59:3.9:2.1 kb, 59:39:2.1 kb, 59:4.5:2.1kb, 59:45 kb, 59:45:2.1 kb, 59:45:3.4 kb, and 59:6.7 kb [ 6 ]. It is important to emphasize that these ten plasmid types have been identified in almost all studied regions of Siberia and the Far East of Russia.…”

“…Our previous studies have shown that the dissemination of some Salmonella populations is more influenced by globalization processes, while other populations of the pathogen are circulated in local poultry farms for years [ 6 ]. We assumed that these features could affect the antibiotic resistance spectrum of Salmonella populations circulating in the administrative territories of Siberia and the Far East of Russia.…”

“…Salmonella enterica subsp. enterica serovar Enteritidis ( S. Enteritidis) is one of the most frequent serovars of zoonotic Salmonella infection in humans worldwide [ 7 ], including Russia [ 1 , 6 , 8 ]. The aim of the study was to compare the antibiotic susceptibility of S. Enteritidis populations that were isolated in different regions of Siberia and the Russian Far East between 1990 and 2017 based on geography, period of isolation, and the plasmid content.…”

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.

“…Specifically, Salmonella enterica subsp. enterica serovar Enteritidis (S. Enteritidis) represented 61.2% of all reported serovars of confirmed human cases in 2017 in the European Union [1] and about 70% of all reported serovars of confirmed human cases in 1988-2018 in Russia [2]. Chickens are known to be the main reservoir for S. Enteritidis [1].…”

Salmonella enterica subsp. enterica serovar Enteritidis is one of the most common zoonotic pathogens. We report here the genome sequence of Salmonella enterica subsp. enterica serovar Enteritidis S-25048 isolated from chicken (Gallus gallus domesticus) meat in Artyom, Russia. The assembled genome size was 4,695,145 bp. A total of 4565 coding genes, four rRNAs, 62 tRNAs, and 14 noncoding RNAs were predicted. To our knowledge, this is the first publically deposited annotated genome of this serovar isolated in Russia. The Salmonella Enteritidis S-25048 genome is suitable for use as a reference strain of Salmonella Enteritidis isolated in Russia.

The idea of using pathogens to control pests has existed since the end of the 19th century. Enterobacteria from the genus Salmonella, discovered at that time, are the causative agents of many serious diseases in mammals often leading to death. Mostly, the strains of Salmonella are able to infect a wide spectrum of hosts belonging to vertebrates, but some of them show host restriction. Several strains of these bacteria have been used as biorodenticides due to the host restriction until they were banned in many countries in the second part of the 20th century. The main reason for the ban was their potential pathogenicity for some domestic animals and poultry and the outbreaks of gastroenteritis in humans. Since that time, a lot of data regarding the host specificity and host restriction of different strains of Salmonella have been accumulated, and the complexity of the molecular mechanisms affecting it has been uncovered. In this review, we summarize the data regarding the history of studying and application of Salmonella-based rodenticides, discuss molecular systems controlling the specificity of Salmonella interactions within its multicellular hosts at different stages of infection, and attempt to reconstruct the network of genes and their allelic variants which might affect the host-restriction mechanisms.
