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:Salmonella enterica spp. are pathogenic bacteria commonly associated with food-borne outbreaks in human and animals. Salmonella enterica spp. are characterized into more than 2,500 different serotypes, which makes epidemiological surveillance and outbreak control more difficult. In this report, we announce the first complete genome and methylome sequences from two Salmonella type strains associated with food-borne outbreaks, Salmonella enterica subsp. enterica serovar Panama (ATCC 7378) and Salmonella enterica subsp. enterica serovar Sloterdijk (ATCC 15791).
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:In enteric bacteria, DNA supercoiling is highly responsive to environmental conditions. Host specific features of environment serve as cues for the expression of genes required for colonization of host niches via changing supercoiling . It has been shown that substitution at position 87 of GyrA of Salmonella enterica str. SL1344 influences global supercoiling and results in an altered transcriptome with increased expression of stress response pathways . Aminocoumarin antibiotics, such as novobiocin, can be used to relax supercoiling and alter the expression of supercoiling-sensitive genes. Meanwhile, Salmonella enterica demonstrates a significant resistance to this antibiotic and relatively small variability of supercoiling in response to the growth phase, osmotic pressure, and novobiocin treatment. Here we present for the first time transcriptome data of Salmonella enterica subsp. Enterica serovar Typhimurium str. 14028S grown in the presence of novobiocin. These data will help identify genes involved in novobiocin resistance and adaptation processes associated with torsion perturbations in S. enterica. Cleaned FASTQ files for the RNA-seq libraries are deposited in the NCBI Sequence Read Archive (SRA, Identifier: SRP239815) and have been assigned BioProject accession PRJNA599397.
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 Thompson strain RM6836 was isolated from lettuce in 2002. We report here the complete sequence and annotation of the genome of S. Thompson RM6836. This is the first reported complete genome sequence for S. Thompson and it will enhance our understanding of this serovar and provide another point for comparative studies between Salmonella enterica strains.
Project description:Single-molecule read technologies allow for detection of epigenomic base modifications during routine sequencing by analysis of kinetic data during the reaction, including the duration between base incorporations at the elongation site (the "inter-pulse duration.") Methylome data associated with a closed de novo bacterial genome of Salmonella enterica subsp. enterica serovar Javiana str. CFSAN001992 was produced and submitted to the Gene Expression Omnibus. Single-sample sequencing and base modification detection of cultured isolate of a foodborne pathogen.
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 subsp. enterica serovar Enteritidis is a common food-borne pathogen, often associated with shell eggs and poultry. Here, we report draft genomes of 21 S. Enteritidis strains associated with or related to the U.S.-wide 2010 shell egg recall. Eleven of these genomes were from environmental isolates associated with the egg outbreak, and 10 were reference isolates from previous years, unrelated to the outbreak. The whole-genome sequence data for these 21 human pathogen strains are being released in conjunction with the newly formed 100K Genome Project.
Project description:The genome of Salmonella enterica subspecies enterica serovar Enteritidis phage type 8 strain EN1660, isolated from an outbreak in Thunder Bay, Canada, was sequenced to 46-fold coverage using an Illumina MiSeq with 300-bp paired-end sequencing chemistry to produce 28 contigs with an N50 value of 490,721 bp.
