The chromosomal methylation statuses of the highly virulent Vibrio vulnificus strain CMCP6 grown in human serum and in seawater are compared here. Growth in seawater resulted in ~4 times as much methylation as that in human serum, primarily N4-methylcytosines.Copyright © 2019 Conrad and Harwood.
We present the whole-genome sequence of an isolate of Auritidibacter ignavus, associated with ear infections. This complete assembly was compared to genomes of four global isolates, which revealed a high diversity within the species.Copyright © 2019 Seth-Smith et al.
Use of indole-3-acetic acid (IAA) as a carbon, nitrogen, and energy source by Pseudomonas putida 1290 is linked to the possession of a gene cluster that codes for conversion to catechol. Here, we present the genomic context of this iac gene cluster, which includes genes for IAA chemotaxis/transport and catechol catabolism.Copyright © 2019 Laird and Leveau.
Staphylococcus aureus multilocus sequence type 398 (ST398) is responsible for an increasing number of severe infections in humans. There are no reports detailing if all ST398 strains are equally virulent. We present the genome sequence of the moderate-virulence ST398 methicillin-susceptible Staphylococcus aureus strain GD1108, determined in a Caenorhabditis elegans infection model, to reveal the ST398 sublineage virulence.Copyright © 2019 McClure et al.
The emerging livestock-associated Staphylococcus aureus multilocus sequence type 398 (ST398) appears to have augmented virulence in humans. However, it is unclear if all ST398 strains are equally virulent. Here, we present the chromosomal sequence of a low-virulence ST398 methicillin-susceptible S. aureus (MSSA) strain, GD1696, to investigate ST398 sublineage virulence.Copyright © 2019 McClure et al.
Here, we report the complete genome sequence of Kocuria indica CE7, isolated from human skin. This strain possesses a 2,809-kbp chromosome and a 32-kbp plasmid with 2,507 coding sequences. In particular, the genome contains multiple genes potentially involved in adaptations in pH homeostasis and salt tolerance.Copyright © 2019 Lee et al.
In this announcement, we present the complete annotated genome sequence of an Escherichia coli MC4100 mutant strain, BE104. This strain has several methionine sulfoxide reductase gene deletions, making it ideal for studying enzymes that alter the redox state of methionine.Copyright © 2019 Anton et al.
The Gram-negative pathogenic spirochetal bacteria Leptospira spp. cause leptospirosis in humans and livestock animals. Leptospira kmetyi strain LS 001/16 was isolated from a soil sample associated with a leptospirosis patient in Kelantan, which is among the states in Malaysia with a high reported number of disease cases. Here, we report the complete genome sequence of Leptospira kmetyi strain LS 001/16. Copyright © 2019 Yusof et al.
High-coverage long-read sequencing of the Halobacterium salinarum type strain (91-R6) revealed a 2.17-Mb chromosome and two large plasmids (148 and 102 kb). Population heterogeneity and long repeats were observed. Strain 91-R6 and laboratory strain R1 showed 99.63% sequence identity in common chromosomal regions and only 38 strain-specific segments. This information resolves the previously uncertain relationship between type and laboratory strains.Copyright © 2019 Pfeiffer et al.
Thermoactinomyces vulgaris strain CDF was isolated from soil and shown to have the ability to degrade chicken feathers at high temperatures. Here, we report the complete genome sequence of this bacterium, which is 2,595,509?bp long with 2,642 predicted genes and an average G+C content of 48.14%.Copyright © 2019 Li et al.
Shiga toxin-producing Escherichia coli O157:H7 is a foodborne pathogen and is responsible for outbreaks of human gastroenteritis. This report documents the draft genome sequences of nine O157:H7 cattle strains, which were identified to be PCR positive for a Shiga toxin gene but displayed different levels of functional toxin activity.
The genomes of two extremely halophilic Archaea species, Haloarcula marismortui and Haloferax mediterranei, were sequenced using single-molecule real-time sequencing. The ~4-Mbp genomes are GC rich with multiple large plasmids and two 4-methyl-cytosine patterns. Methyl transferases were incorporated into the Restriction Enzymes Database (REBASE), and gene annotation was incorporated into the Haloarchaeal Genomes Database (HaloWeb).Copyright © 2019 DasSarma et al.
Multilocus sequence type 398 (ST398) methicillin-susceptible Staphylococcus aureus (MSSA) has been shown to have augmented pathogenicity in humans. However, it has not been determined whether all ST398 strains are equally virulent. We present here the genome sequence of a high-virulence ST398 MSSA strain, GD487, to explore potential insights into ST398 virulence.Copyright © 2019 McClure et al.
Raoultella terrigena is a bacterial species associated with soil and aquatic environments; however, sporadic cases of opportunistic disease in humans have been reported. Here, we report the first two complete genome sequences from clinical strains isolated from human sources that have been deposited in the National Collection of Type Cultures (NCTC). © Crown copyright 2019.
Leuconostoc kimchii strain NKJ218 was isolated from homemade kimchi in South Korea. The whole genome was sequenced using the PacBio RS II and Illumina NovoSeq 6000 platforms. Here, we report a genome sequence of strain NKJ218, which consists of a 1.9-Mbp chromosome and three plasmid contigs. A total of 2,005 coding sequences (CDS) were predicted, including 1,881 protein-coding sequences.Copyright © 2019 Jung et al.
