The Mycoplasma phocicerebrale genome was analyzed to better understand this opportunistic pathogen. Amplification with ?29 polymerase was used to generate enough genomic DNA for large-insert library construction. Like other mycoplasmas from seals, M. phocicerebrale encodes an immunosuppressor that may predispose susceptibility to infection or influence intercurrent diseases of affected hosts.Copyright © 2019 Frasca et al.

Haemophilus haemolyticus is a Gram-negative bacterium that is a commensal of the respiratory tract in humans. Here, we report the complete genome sequence available for Haemophilus haemolyticus strain NCTC 10839, which was originally isolated from the nasopharynx of a child. © Crown copyright 2019.
We report the draft whole-genome sequence of Alteromonas sp. strain RKMC-009, which was isolated in situ from the sponge Xestospongia muta in San Salvador, The Bahamas, using an isolation chip (ichip). Automated biosynthetic gene cluster analysis using antiSMASH 4.0 predicted the presence of 22 biosynthetic gene clusters.Copyright © 2019 MacIntyre et al.
We report the draft genome sequence of Monascus purpureus GB-01, an industrial strain used as a food colorant. De novo assembly of long reads resulted in 121 chromosomal contigs and 1 mitochondrial contig, and sequencing errors were corrected by paired-end short reads. This genome sequence will provide useful information for azaphilone pigments and mycotoxin citrinin biosynthesis.Copyright © 2019 Kumagai et al.
Citrobacter rodentium strain DBS100 causes an infection of the intestines in mice. It provides an important model for human gastrointestinal pathogens, such as enteropathogenic and enterohemorrhagic Escherichia coli, which cause life-threatening infections. To identify the genetic determinants that are common across the enteropathogenic bacteria, we sequenced the DBS100 genome.Copyright © 2019 Popov et al.
Here, we announce the complete genome sequence of Streptococcus pyogenes strain 10-85 (type emm1), isolated from a patient with streptococcal toxic shock syndrome (STSS). The strain lacks the genomic regions encoding SalR-SalK, a two-component regulatory system, and the adjacent type I restriction modification system.Copyright © 2019 Tatsuno et al.
Here, we report the draft genome sequence of Mesosutterella multiformis JCM 32464T, a new member of the family Sutterellaceae that was isolated from human feces. The genome assembly comprised 2,621,983?bp, with a G+C content of 56.9%. This genomic analysis will be useful for understanding the metabolic activities of this asaccharolytic bacterium.Copyright © 2019 Ikeyama et al.
The hospital-acquired methicillin-resistant Staphylococcus aureus (HA-MRSA) strain WCUH29 has been intensively and widely used as a model system for identification and evaluation of novel antibacterial targets and pathogenicity. In this announcement, we report the complete genome sequence of HA-MRSA WCUH29 (NCIMB 40771).Copyright © 2019 Lei et al.
A new strain of Streptomyces sp., strain RFCAC02, was isolated from the gut of the Pacific chub mackerel Scomber japonicus peruanus This strain produces a variety of secondary metabolites. Further bioinformatic analysis revealed the presence of biosynthetic gene clusters putatively coding for compounds related to the polycyclic tetramate macrolactams (PTMs).Copyright © 2019 Serrano et al.
Culture-based molecular identification methods have revolutionized detection of pathogens, yet these methods are slow and may yield inconclusive results from environmental materials. The second-generation sequencing tools have much-improved precision and sensitivity of detection, but these analyses are costly and may take several days to months. Of the third-generation sequencing techniques, the portable MinION device (Oxford Nanopore Technologies) has received much attention because of its small size and possibility of rapid analysis at reasonable cost. Here, we compare the relative performances of two third-generation sequencing instruments, MinION and Sequel (Pacific Biosciences), in identification and diagnostics of fungal and oomycete pathogens from conifer (Pinaceae) needles and potato (Solanum tuberosum) leaves and tubers. We demonstrate that the Sequel instrument is efficient for metabarcoding of complex samples, whereas MinION is not suited for this purpose due to a high error rate and multiple biases. However, we find that MinION can be utilized for rapid and accurate identification of dominant pathogenic organisms and other associated organisms from plant tissues following both amplicon-based and PCR-free metagenomics approaches. Using the metagenomics approach with shortened DNA extraction and incubation times, we performed the entire MinION workflow, from sample preparation through DNA extraction, sequencing, bioinformatics, and interpretation, in 2.5 h. We advocate the use of MinION for rapid diagnostics of pathogens and potentially other organisms, but care needs to be taken to control or account for multiple potential technical biases.IMPORTANCE Microbial pathogens cause enormous losses to agriculture and forestry, but current combined culturing- and molecular identification-based detection methods are too slow for rapid identification and application of countermeasures. Here, we develop new and rapid protocols for Oxford Nanopore MinION-based third-generation diagnostics of plant pathogens that greatly improve the speed of diagnostics. However, due to high error rate and technical biases in MinION, the Pacific BioSciences Sequel platform is more useful for in-depth amplicon-based biodiversity monitoring (metabarcoding) from complex environmental samples.Copyright © 2019 American Society for Microbiology.
Herein, we report the complete genome sequence of Enterococcus faecium QU50, isolated from Egyptian soil and exhibiting intermediate susceptibility to vancomycin.

Lactobacillus plantarum NCIMB 700965 was isolated from cheese in 1939 and is used as an indicator strain for plantaricin production. The complete genome was determined using both long (PacBio) and short (Illumina) read data resulting in a single, circular chromosome with 3,015,426 bp, a G+C content of 45%, and five plasmids.Copyright © 2019 Heeney and Marco.
Melissococcus plutonius attacks honeybee larvae, causing European foulbrood. Based on their virulence toward larvae, M. plutonius isolates were classified into three types, highly virulent, moderately virulent, and avirulent. We herein performed whole-genome sequencing of M. plutonius isolates with different virulence levels to promote an understanding of the pathogenesis of this disease.Copyright © 2019 Okumura et al.
