Project description:Salmonella enterica constitutes a group of enteric pathogens with a broad host range, including humans, reptiles, and birds. S. enterica subsp. enterica is a common cause of inflammatory diarrhea in humans. We present the draft genome of S. enterica subsp. enterica serovar Enteritidis strain SEJ, including a 59-kbp plasmid.
Project description:Salmonella enterica subsp. enterica serovar Enteritidis is an important zoonotic food-borne pathogen causing serious human illnesses frequently linked to poultry products. Here, we report fully assembled genome sequences of 16 S. Enteritidis strains with common pulsed-field gel electrophoresis (PFGE) and phage types (8, 13, 13a, and 14b) that predominate in North America.
Project description:Bacteriophages infecting Salmonella enterica subsp. enterica serovar Enteritidis may be used as biocontrol agents in food products or animals for preventing foodborne diseases caused by this pathogen. The complete genome sequence of phage Seafire, a T5-like siphophage infecting S. Enteritidis, is described in this report.
Project description:Hybrid assembly of Illumina and Oxford Nanopore sequencing was used here to produce the complete circular genome and plasmid sequences of Salmonella enterica subsp. enterica serovar Enteritidis PT1 (phage type 1). The organism was obtained from the Salmonella Reference Laboratory at Public Health England, Colindale, UK.
Project description:We report the high-quality draft genome sequences of 162 strains of Salmonella enterica subsp. enterica serovar Enteritidis representing diverse phage types and pulsed-field gel electrophoresis (PFGE) profiles. The analysis of these genomes will enable the identification of markers that are useful for differentiating strains of this highly clonal serovar and will provide insights into the evolution, virulence, and epidemiology of the strains.
Project description:Salmonella enterica subsp. enterica serovar Enteritidis is a prominent cause of human salmonellosis frequently linked to poultry products. In Canada, S. Enteritidis phage types 8, 13, and 13a predominate among both clinical and poultry isolates. Here, we report the complete genome and plasmid sequences of poultry isolates of these three phage types.
Project description:Egg-associated salmonellosis is an important public health problem in many countries. Here, we report the genome sequences, including plasmids, of two strains of Salmonella enterica subsp. enterica serovar Enteritidis isolated from egg products in 2012 and 2013 in the United States. This will provide more information and insight into the research about egg-associated salmonellosis.
Project description:Salmonella enterica serovar Enteritidis has remained a major food-borne pathogen in humans. We isolated a virulent S. enterica serovar Enteritidis bacteriophage, SE2, which belongs to the family Siphoviridae. Phage SE2 could lyse S. enterica serovar Enteritidis PT-4, and its virulence was maintained even at ambient temperature. The genomic sequence of phage SE2 was composed of 43,221 bp with close similarity to those of Salmonella phage SETP3 and Salmonella phage SS3e. The strong and stable lytic activity of this phage might enable its use as a therapeutic or biocontrol agent against S. enterica serovar Enteritidis.
Project description:The crystal structure of SEp22, a DNA-binding protein from starved cells from Salmonella enterica subsp. enterica serovar Enteritidis, has been determined in two forms: the native state at 1.25 Å resolution and an iron-soaked form at 1.30 Å resolution. The SEp22 protomers form a dodecameric shell with 23 symmetry and a single iron ion per protomer was found at the ferroxidase centre in the iron-soaked form. Along the threefold axes of the 23 symmetry, hydrophilic Asp channels that consist of Asp146 were found. Iron ions may flow into the cavity of the dodecameric shell through the Asp channels.
Project description:Salmonella enterica subsp. enterica serovar Enteritidis has been the prevalent serovar isolated from gastroenteritis cases in Brazil since the 1990s. Here, we report the draft genomes of 30 S Enteritidis isolates originating from a variety of patients and implicated foods during outbreaks between 1999 and 2006 in Brazil.
