We report here the completed closed genome sequences of strains representing 36 serotypes of Salmonella. These genome sequences will provide useful references for understanding the genetic variation between serotypes, particularly as references for mapping of raw reads or to create assemblies of higher quality, as well as to aid in studies of comparative genomics of Salmonella.© Crown copyright 2018.
Salmonella enterica serovar Enteritidis is one of the most commonly isolated foodborne pathogens and is transmitted primarily to humans through consumption of contaminated poultry and poultry products. We are reporting completely closed genome and plasmid sequences of historical S. Enteritidis isolates recovered from humans between 1949 and 1995 in the United States.
Escherichia spp., including E. albertii and E. coli, Shigella dysenteriae, and S. flexneri are causative agents of foodborne disease. We report here reference-level whole-genome sequences of E. albertii (2014C-4356), E. coli (2011C-4315 and 2012C-4431), S. dysenteriae (BU53M1), and S. flexneri (94-3007 and 71-2783)..

The sequence type 131 (ST131)-H30 clone is responsible for a significant proportion of multidrug-resistant extraintestinal Escherichia coli infections. Recently, the C1-M27 clade of ST131-H30, associated with blaCTX-M-27, has emerged. The complete genome sequence of E. coli isolate 81009 belonging to this clone, previously used during the development of ST131-specific monoclonal antibodies, is reported here.

We report here the first complete genome sequence of a human Pseudomonas lundensis isolate, strain AU1044, and the draft genomes of 11 other clinical P. lundensis strains, isolated from the lungs of cystic fibrosis patients. The genome of strain AU1044 is 4.81 Mb and encodes seven 16S rRNAs.
We report here the complete genome sequence of Escherichia coli strain ML35. We assembled PacBio reads into a single closed contig with 169× mean coverage and then polished this contig using Illumina MiSeq reads, yielding a 4,918,774-bp sequence with 50.8% GC content. Copyright © 2018 Casale et al.
Urinary tract infections (UTIs) are among the most common infections in humans, predominantly caused by uropathogenic Escherichia coli (UPEC). The diverse genomes of UPEC strains mostly impede disease prevention and control measures. In this study, we comparatively analyzed the whole genome sequence of a highly virulent UPEC strain, namely UPEC 26-1, which was isolated from urine sample of a patient suffering from UTI in Korea. Whole genome analysis showed that the genome consists of one circular chromosome of 5,329,753 bp, comprising 5064 protein-coding genes, 122 RNA genes (94 tRNA, 22 rRNA and 6 ncRNA genes), and 100 pseudogenes, with an average G+C content of 50.56%. In addition, we identified 8 prophage regions comprising 5 intact, 2 incomplete and 1 questionable ones and 63 genomic islands, suggesting the possibility of horizontal gene transfer in this strain. Comparative genome analysis of UPEC 26-1 with the UPEC strain CFT073 revealed an average nucleotide identity of 99.7%. The genome comparison with CFT073 provides major differences in the genome of UPEC 26-1 that would explain its increased virulence and biofilm formation. Nineteen of the total GIs were unique to UPEC 26-1 compared to CFT073 and nine of them harbored unique genes that are involved in virulence, multidrug resistance, biofilm formation and bacterial pathogenesis. The data from this study will assist in future studies of UPEC strains to develop effective control measures.
Shigella spp. are enteric pathogens that cause shigellosis. We report here the high-quality whole-genome sequences of 59 historical Shigella strains that represent the four species and a variety of serotypes.
Escherichia coli O145:H11 strain RM14721 was originally isolated from wildlife feces near a leafy greens-growing region in Yuma, AZ. This strain was initially positive for stx1; however, in subsequent cultures, stx1 was not detected by PCR. Here, we report the complete genome sequence and annotation of RM14721.
Carbapenems are considered last-resort antibiotics used to treat human infections caused by multidrug-resistant bacteria. In 2011, VIM-1 carbapenemase-producing Salmonella enterica subsp. enterica serovar Infantis strains were isolated from livestock for the first time in Germany. Here, we announce the complete genome sequence of the first German blaVIM-1-harboring Salmonella Infantis isolate (15-SA01028) originating from food. Copyright © 2018 Borowiak et al.
The genome of Salmonella enterica subsp. enterica serotype Senftenberg N17-509, a strain isolated from desiccated coconut, was sequenced using single-molecule real-time sequencing. It consists of a 5.1-Mbp chromosome and a 29-kb linear plasmid. Copyright © 2018 Stevens et al.
Strains of the ciprofloxacin-resistant (Cipr) Salmonella enterica subsp. enterica serovar Kentucky sequence type 198 (ST198) have rapidly and extensively disseminated globally to become a major food safety and public health concern. Here, we report the complete genome sequence of a CiprS. Kentucky ST198 strain, PU131, isolated from a human patient in Washington State (USA).
The genomes of many strains of Escherichia coli have been sequenced, as this organism is a classic model bacterium. Here, we report the genome sequence of Escherichia coli DH5a, which is resistant to a T4 bacteriophage (CCTCC AB 2015375), while its other homologous E. coli strains, such as E. coli BL21, DH10B, and MG1655, are not resistant to phage invasions. Thus, understanding of the genome of the DH5a strain, along with comparative analysis of its genome sequence along with other sequences of E. coli strains, may help to reveal the bacteriophage resistance mechanism of E. coli.

Escherichia albertii has recently been recognized as an emerging human and bird enteric pathogen. Here, we report the complete chromosome sequence of a clinical isolate of E. albertii strain 1551-2, which may provide information about the pathogenic potential of this new species and the mechanisms of evolution of Escherichia species.
