Marivivens sp. JLT3646 (CGMCC 1.15778), belonging to the phylum Alphaproteobacteria, was isolated from seawater, Kueishan Islet, offshore northeast of Taiwan. Here, we present the complete genome sequence of Marivivens sp. JLT3646, which contains a circular 2,978,145 bp chromosome with 56.2% G + C content, and one circular plasmid which is 169,066 bp in length. The genome data suggested that Marivivens sp. JLT3646 has the potential to degrade aromatic monomers, which might provide insight into biotechnological applications and facilitate the investigation of environmental bioremediation.
Zinc resistance in livestock-associated methicillin resistant Staphylococcus aureus (LA-MRSA) sequence type (ST) 398 is primarily mediated by the czrC gene co-located with the mecA gene, encoding methicillin resistance, within the type V SCCmec element. Because czrC and mecA are located within the same mobile genetic element, it has been suggested that the use of in feed zinc as an antidiarrheal agent has the potential to contribute to the emergence and spread of MRSA in swine through increased selection pressure to maintain the SCCmec element in isolates obtained from pigs. In this study we report the prevalence of the czrC gene…
The bla NDM-1 gene in Salmonella species is mostly reported in clinical cases, but is rarely isolated from red and white meat in China.A Salmonella Indiana (S. Indiana) isolate was cultured from a chicken carcass procured from a slaughterhouse in China. Antimicrobial susceptibility was tested against a panel of agents. Whole-genome sequencing of the isolate was carried out and data was analyzed.A large plasmid, denoted as plasmid pC629 (210,106 bp), containing a composite cassette, consisting of IS26-bla NDM-1-ble MBL -?trpF-tat-cutA-ISCR1-sul1-qacE?1-aadA2-dfrA12-intI1-IS26 was identified. The latter locus was physically linked with bla OXA-1, bla CTX-M-65, bla TEM-1-encoding genes. A mercury resistance operon merACDEPTR…
Streptococcus salivarius strains are significant contributors to the human oral microbiome. Some possess unique fimbriae that give them the ability to coaggregate and colonize particular oral structures. We present here the complete genomes of Streptococcus salivarius Lancefield K(-)/K(+) strains ATCC 25975 and ATCC 27945, which can and cannot, respectively, produce fimbriae.

Legionella longbeachae serogroup 1, predominantly found in soil and composted plant material, causes the majority of cases of Legionnaires' disease (LD) in New Zealand. Here, we report the complete genome sequence of an L. longbeachae serogroup 1 (sg1) isolate derived from a patient hospitalized with LD in Christchurch, New Zealand. Copyright © 2017 Slow et al.
Coral reefs are a complex ecosystem consisting of coral animals and a vast array of associated symbionts including the dinoflagellate Symbiodinium, fungi, viruses and bacteria. Several studies have highlighted the importance of coral-associated bacteria and their fundamental roles in fitness and survival of the host animal. The scleractinian coral Porites lutea is one of the dominant reef-builders in the Indo-West Pacific. Currently, very little is known about the composition and structure of bacterial communities across P. lutea reefs. The purpose of this study is twofold: to demonstrate the advantages of using PacBio circular consensus sequencing technology in microbial community studies…
Complete and accurate reference genomes and annotations provide fundamental tools for characterization of genetic and functional variation. These resources facilitate the determination of biological processes and support translation of research findings into improved and sustainable agricultural technologies. Many reference genomes for crop plants have been generated over the past decade, but these genomes are often fragmented and missing complex repeat regions. Here we report the assembly and annotation of a reference genome of maize, a genetic and agricultural model species, using single-molecule real-time sequencing and high-resolution optical mapping. Relative to the previous reference genome, our assembly features a 52-fold increase…
Four complete genome sequences of genetically distinct Paenibacillus larvae strains have been determined. Pacific BioSciences single-molecule real-time (SMRT) sequencing technology was used as the sole method of sequence determination and assembly. The chromosomes exhibited a G+C content of 44.1 to 44.2% and a molecular size range of 4.29 to 4.67 Mbp. Copyright © 2017 Dingman.
Staphylococcus epidermidis 1457 is a frequently utilized strain that is amenable to genetic manipulation and has been widely used for biofilm-related research. We report here the whole-genome sequence of this strain, which encodes 2,277 protein-coding genes and 81 RNAs within its 2.4-Mb genome and plasmid. Copyright © 2017 Galac et al.
Bacillus subtilis GQJK2 is a plant growth-promoting rhizobacterium with antifungal activity which was isolated from Lycium barbarum L. rhizosphere. Here, we report the complete genome sequence of B. subtilis GQJK2. Ten gene clusters involved in the biosynthesis of antagonistic compounds were predicted. Copyright © 2017 Ma et al.
Neisseria meningitidis causes meningococcal disease, often resulting in fulminant meningitis, sepsis, and death. Vaccination programs have been developed to prevent infection of this pathogen, but serogroup replacement is a problem. Capsular switching has been an important survival mechanism for N. meningitidis, allowing the organism to evolve in the present vaccine era. However, related mechanisms have not been completely elucidated. Genetic analysis of capsular switching between diverse serogroups would help further our understanding of this pathogen. In this study, we analyzed the genetic characteristics of the sequence type 7 (ST-7) serogroup X strain that was predicted to arise from ST-7 serogroup…
Escherichia coli is the most common bacterium causing urinary tract infections in humans. We report here the complete genome sequence of the uropathogenic Escherichia coli strain NU14, a clinical pyelonephritis isolate used for studying pathogenesis. Copyright © 2017 Mehershahi and Chen.
Lactobacillus curvatus WiKim38 is a potential probiotic strain isolated from kimchi, a traditional Korean fermented food. The complete genome of the WiKim38 strain consisted of a circular chromosome of 1,940,170 bp in length with a G+C content of 41.93%. Copyright © 2017 Lee et al.
Microbiologically induced calcium carbonate precipitation shows the potential for use in bioremediation and construction consolidation, but the efficiency of this process must be improved. Lysinibacillus sphaericus LMG 22257 is a gram-positive ureolytic strain that has recently been applied for consolidating construction by mediating calcium carbonate precipitation. The complete genome sequence of L. sphaericus LMG 22257 is 3,436,578 base pairs with a GC content of 38.99%. The urea degradation pathway and genes related to extracellular polymeric substance biosynthesis were also identified. The strain can tolerate high alkalinity (pH up to 10) and high urea concentration (up to 3M). These findings provide…
Streptococcus thermophilus ACA-DC 2 is a newly sequenced strain isolated from traditional Greek yogurt. Among the 14 fully sequenced strains of S. thermophilus currently deposited in the NCBI database, the ACA-DC 2 strain has the smallest chromosome, containing 1,731,838 bp. The annotation of its genome revealed the presence of 1,850 genes, including 1,556 protein-coding genes, 70 RNA genes and 224 potential pseudogenes. A large number of pseudogenes were identified. This was also accompanied by the absence of pathogenic features suggesting evolution of strain ACA-DC 2 through genome decay processes, most probably due to adaptation to the milk ecosystem. Analysis revealed the…
