Escherichia coli sequence type 131 (ST131) is the most frequent antimicrobial-resistant lineage of E. coli, propagating extended-spectrum ß-lactamases (ESBL) worldwide. Recently, an alarming rate of increase in isolates of the sublineage C1/H30R-blaCTX-M-27 of ST131 in geographically distant countries was reported. Here, we present the complete genome sequence of the ST131 sublineage C1/H30R E. coli isolate harboring blaCTX-M-27 from Germany. Copyright © 2017 Ghosh et al.
Streptomyces autolyticus CGMCC 0516 produces the anti-tumor benzoquinone ansamycins geldanamycin, autolytimycin, and reblastatin and the 16-membered macrodiolide elaiophylin. Here, we report the complete genome sequence of S. autolyticus CGMCC 0516, which consists of a 10,029,028bp linear chromosome and seven circular plasmids. Fifty-seven putative biosynthetic gene clusters for secondary metabolites were found. The geldanamycin, autolytimycin, and reblastatin biosynthetic gene clusters were located on the left arm (2.06-2.15Mb) of the chromosome, and the elaiophylin gene cluster was located on the right arm (9.45-9.53Mb). Twenty-one putative gene clusters with high or moderate similarity to important antibiotic biosynthetic gene clusters were found, including the antitumor agents echoside, bafilomycin, hygrocin, and toxoflavin; the antibacterial/antifungal agents nigericin, skyllamycin, kanamycin, naphthomycin, eco-02301, and bottromycin A2; the immunosuppressants meridamycin and brasilicardin A; the anti-inflammatory agent cyclooctatin; and the acute iron poisoning medication desferrioxamine B. The genome sequence reported here will enable us to study the biosynthetic mechanism of these important antibiotics and will facilitate the discovery of novel secondary metabolites with potential applications to human health.

The thermophilic spore-forming bacterium Anoxybacillus flavithermus is responsible for powdered milk product spoilage, and its presence in dairy processing environments is a concern. Here, the complete genome sequence of the A. flavithermus strain 52-1A isolated from a heat-processed powdered milk product concentrate in Switzerland is presented. Copyright © 2017 Tasara et al.
Tenacibaculum maritimum is a devastating bacterial pathogen of wild and farmed marine fish with a broad host range and a worldwide distribution. We report here the complete genome sequence of the T. maritimum type strain NCIMB 2154(T). The genome consists of a 3,435,971-base pair circular chromosome with 2,866 predicted protein-coding genes. Genes encoding the biosynthesis of exopolysaccharides, the type IX secretion system, iron uptake systems, adhesins, hemolysins, proteases, and glycoside hydrolases were identified. They are likely involved in the virulence process including immune escape, invasion, colonization, destruction of host tissues, and nutrient scavenging. Among the predicted virulence factors, type IX secretion-mediated and cell-surface exposed proteins were identified including an atypical sialidase, a sphingomyelinase and a chondroitin AC lyase which activities were demonstrated in vitro.
Members of the genus Hafnia have been isolated from the feces of mammals, birds, reptiles, and fish, as well as from soil, water, sewage, and foods. Hafnia alvei is an opportunistic pathogen that has been implicated in intestinal and extraintestinal infections in humans. However, its pathogenicity is still unclear. In this study, we isolated H. alvei from human feces and performed sequencing as well as comparative genomic analysis to better understand its pathogenicity.The genome of H. alvei CBA7124 comprised a single circular chromosome with 4,585,298 bp and a GC content of 48.8%. The genome contained 25 rRNA genes (9 5S rRNA genes, 8 16S rRNA genes, and 8 23S rRNA genes), 88 tRNA genes, and 4043 protein-coding genes. Using comparative genomic analysis, the genome of this strain was found to have 72 strain-specific singletons. The genome also contained genes for antibiotic and antimicrobial resistance, as well as toxin-antitoxin systems.We revealed the complete genome sequence of the opportunistic gut pathogen, H. alvei CBA7124. We also performed comparative genomic analysis of the sequences in the genome of H. alvei CBA7124, and found that it contained strain-specific singletons, antibiotic resistance genes, and toxin-antitoxin systems. These results could improve our understanding of the pathogenicity and the mechanism behind the antibiotic resistance of H. alvei strains.
We report here the complete genome sequence of Clostridioides difficile strain DH/NAP11/106/ST-42, which is now the most common strain causing C. difficile infection among U.S. adults. This strain was isolated from the stool from a hospitalized pediatric patient with frequent relapses of C. difficile infection. Copyright © 2017 Ozer et al.
Staphylococcus epidermidis ATCC 12228 was sequenced using a long-read method to generate a complete genome sequence, including some plasmid sequences.
