Escherichia coli Mt1B1, a mouse isolate, is a facultative anaerobic bacterium which was shown to counteract Salmonella enterica serovar Typhimurium infection in a mouse model. In the present study, we describe the complete genome sequence of E. coli Mt1B1, composed of a 5.1-Mb chromosome and a 62.6-kb plasmid. Copyright © 2018 Garzetti et al.
Silent biosynthetic gene clusters represent a potentially rich source for new bioactive compounds. We report the discovery, characterization and biosynthesis of a novel doubly glycosylated 24-membered polyene macrolactam from a silent biosynthetic gene cluster in Streptomyces roseosporus using the CRISPR-Cas9 gene cluster activation strategy. Structural characterization of this polyketide, named auroramycin, revealed a rare isobutyrylmalonyl extender unit and a unique pair of aminosugars. Relative and absolute stereochemistry were determined using a combination of spectroscopic analyses, chemical derivatization, and computational analysis. The activated gene cluster for auroramycin production was also verified by transcriptional analyses and gene deletions. Finally, auroramycin exhibited potent anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) activity towards clinical drug-resistant isolates.© 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
Vibrio parahaemolyticus is a clinically significant marine bacterium implicated in gastroenteritis among consumers of raw or undercooked seafood. This report presents the whole-genome sequence of a unique strain of V. parahaemolyticus isolated from oysters harvested in Canada.© Crown copyright 2018.
Bacteriophage therapy can potentially reduce Campylobacter jejuni numbers in livestock, but it requires a detailed understanding of phage-host interactions. C. jejuni strains readily infected by certain phages are designated as phage-propagating strains. Here, we report the complete genome sequences of three such strains, NCTC 12660, NCTC 12661, and NCTC 12664. Copyright © 2018 Sacher et al.
The acute hepatopancreatic necrosis disease (AHPND) of Penaeus vannamei shrimp is caused by Vibrio parahaemolyticus carrying toxin genes, pirA and pirB We report the complete genome sequence of the novel V. parahaemolyticus strain R14, which did not display AHPND symptoms in P. vannamei despite containing the binary toxin genes.

We report here the complete genome sequence of Campylobacter jejuni strain 12567, a member of a C. jejuni livestock-associated clade that expresses glycoconjugates associated with improved gastrointestinal tract persistence. Copyright © 2018 Sacher et al.
The complete genome sequence of Bacillus subtilis strain DKU_NT_02, isolated from traditional Korean food using soybeans (chung-gook-jang), is presented here. This strain was chosen to help identify genetic factors with high-quality poly-?-glutamic acid (?PGA) activity. Copyright © 2018 Bang et al.
Here, we report the complete genome sequences of three Bacillus amyloliquefaciens strains isolated from alfalfa, almond drupes, and grapes that inhibited the growth of Listeria monocytogenes strain 2011L-2857 in vitro We also report multiple gene clusters encoding secondary metabolites that may be responsible for the growth inhibition of L. monocytogenes.

We present here the genome sequences of Shewanella baltica strain CW2 and Shewanella morhuae strain CW7, isolated from the gastrointestinal tract of Salvelinus namaycush (lean lake trout) and Coregonus clupeaformis (whitefish), respectively. These genome sequences provide insights into the niche adaptation of these specific species in freshwater systems. Copyright © 2018 Castillo et al.
We present here the complete genome sequence of Bacillus subtilis strain DKU_NT_03 isolated from the traditional Korean food chung-gook-jang, which is made from soybeans. This strain was chosen to identify genetic factors with high-quality nattokinase activity. Copyright © 2018 Jeong et al.
Mycobacterium shigaense is a slowly growing scotochromogenic species and a member of the Mycobacterium simiae complex group. Here, we report the complete sequence of its genome, comprising a 5.2-Mb chromosome. The sequence will represent the essential data for future phylogenetic and comparative genome studies of the Mycobacterium simiae complex group. Copyright © 2018 Yoshida et al.
Here, we report the complete genome sequence for Bacillus megaterium strain YC4-R4, a highly salt-tolerant rhizobacterium that promotes growth in plants. The sequencing process was performed by combining pyrosequencing and single-molecule sequencing techniques. The complete genome is estimated to be approximately 5.44 Mb, containing a total of 5,673 predicted protein-coding DNA sequences (CDSs). Copyright © 2018 Vílchez et al.
Here, we report the draft genome sequence of Lawsonibacter asaccharolyticus JCM 32166T, a butyrate-producing bacterium, isolated from human feces. The genomic analysis reveals genes for butyrate synthesis and will facilitate the study on the role of this strain in the human gut. Copyright © 2018 Sakamoto et al.
Lactobacillus plantarum LQ80 is a strain isolated from liquid feed for pigs. We determined the complete genome sequence of this strain using the PacBio RS II platform. LQ80 contained a single circular chromosome of 3,230,192 bp, with 44.66% G+C content and seven plasmids. Copyright © 2018 Moriya et al.
We report here the complete genome sequence of the Vibrio cholerae O1 bv. El Tor Ogawa strain V060002, isolated in 1997. The data demonstrate that this clinical strain has a single chromosome resulting from recombination of two prototypical chromosomes. Copyright © 2018 Yamamoto et al.
