Vibrio coralliilyticus RE22 is an indigenous marine pathogen that infects larval bivalve shellfish. This strain is particularly problematic in oyster hatcheries, where it causes high larval mortality. It contains two circular chromosomes and one megaplasmid. Annotation reveals multiple genes which may encode important virulence factors.
Here, we report the whole-genome sequence of Sphingomonas sp. strain FARSPH, isolated from an insect cell line as a contaminant. FARSPH shared high identity with Sphingomonas melonis and Sphingomonas aquatilis strains. Due to this finding, we recommend taking this genus into consideration for cell culture quality control.

We present the complete genome sequence of Bradyrhizobium ottawaense strain OO99T, a nitrogen-fixing bacterium from root nodules of soybean. The genome consists of a single 8.6-Mb chromosome and includes a symbiosis island. Genes involved in symbiotic nitrogen fixation, stress response, resistance to antibiotics, and toxic compounds were detected.
Here, we present an updated genome assembly of the diploid chytrid fungus Batrachochytrium dendrobatidis strain RTP6. This strain is part of the global panzootic lineage (BdGPL) and was isolated in Dunedin, New Zealand. The assembly was generated using PacBio long-read and Illumina short-read data, allowing for the accurate phasing of heterozygosities.
The extensively antibiotic-resistant Acinetobacter baumannii isolate WM99c recovered in Sydney, Australia, in 1999 is an early representative of a distinct lineage of global clone 2 (GC2) seen on the east coast of Australia. We present the complete 4.121-Mbp genome sequence (chromosome plus 2 plasmids), generated via long-read sequencing (PacBio).
We present here the complete genome sequence of Lactococcus lactis strain 14B4, isolated from almond drupes in northern California. This strain was observed to inhibit the growth of Salmonella enterica serotype Poona strain RM3363 in vitro.
Lactic acid bacteria (LAB) are generally recognized as safe (GRAS) and serve as probiotic bacteria when consumed in adequate amounts. Here, we report the complete genome sequence of Lactobacillus reuteri Byun-re-01, isolated from mouse small intestine.
Clostridium formicoaceticum, a Gram-negative mixotrophic homoacetogen, produces acetic acid as the sole metabolic product from various carbon sources, including fructose, glycerol, formate, and CO2. Its genome of 4.59-Mbp contains a highly conserved Wood-Ljungdahl pathway gene cluster with the same layout as that in other mixotrophic acetogens, including Clostridium aceticum, Clostridium carboxidivorans, and Clostridium ljungdahlii. For energy conservation, C. formicoaceticum does not have all the genes required for the synthesis of cytochrome or quinone used for generating proton gradient in H+-dependent acetogens such as Moorella thermoacetica; instead, it has the Rnf system and a Na+-translocating ATPase similar to the one in Acetobacterium woodii. Its growth in both heterotrophic and autotrophic media were dependent on the sodium concentration. C. formicoaceticum has genes encoding acetaldehyde dehydrogenases, alcohol dehydrogenases, and aldehyde oxidoreductases, which could convert acetyl-CoA and acetate to ethanol and butyrate to butanol under excessive reducing equivalent conditions.

Streptomyces sp. SHP22-7 is a novel strain isolated from a mangrove sample on Enggano Island, Indonesia. Here, we present the 7.9-Mbp genome sequence of SHP22-7, which will provide insight into its natural compound biosynthetic potential.
Lactobacillus reuteri SKKU-OGDONS-01 is a potentially indigenous probiotic strain isolated from the small intestine of a 27-week-old chicken. The complete genome of L. reuteri SKKU-OGDONS-01 comprises a single circular chromosome. Its length is 2,259,968?bp, with a G+C content of 38.9%.
The a/ß T cell receptor (TR) is a complex heterodimer that recognizes antigenic peptides and binds to major histocompatibility complex (MH) molecules. Both a and ß chains are encoded by different genes localized on two distinct chromosomal loci: TRA and TRB. The present study employed the recent release of the swine genome assembly to define the genomic organization of the TRB locus. According to the sequencing data, the pig TRB locus spans approximately 400 kb of genomic DNA and consists of 38 TRBV genes belonging to 24 subgroups located upstream of three in tandem TRBD-J-C clusters, which are followed by a TRBV gene in an inverted transcriptional orientation. Comparative analysis confirms that the general organization of the TRB locus is similar among mammalian species, but the number of germline TRBV genes varies greatly even between species belonging to the same order, determining the diversity and specificity of the immune response. However, sequence analysis of the TRB locus also suggests the presence of blocks of conserved homology in the genomic region across mammals. Furthermore, by analysing a public cDNA collection, we identified the usage pattern of the TRBV, TRBD, and TRBJ genes in the adult pig TRB repertoire, and we noted that the expressed TRBV repertoire seems to be broader and more diverse than the germline repertoire, in line with the presence of a high level of TRBV gene polymorphisms. Because the nucleotide differences seems to be principally concentrated in the CDR2 region, it is reasonable to presume that most T cell ß-chain diversity can be related to polymorphisms in pig MH molecules. Domestic pigs represent a valuable animal model as they are even more anatomically, genetically and physiologically similar to humans than are mice. Therefore, present knowledge on the genomic organization of the pig TRB locus allows the collection of increased information on the basic aspects of the porcine immune system and contributes to filling the gaps left by rodent models.
Arcobacter cryaerophilus was originally recovered from aborted bovine and porcine fetuses, but it has been subsequently isolated from meat, water, and human clinical samples. This study describes the complete whole-genome sequences of two A. cryaerophilus strains, ATCC 43158T (=A 169/BT =LMG 24291T) and ATCC 49615 (=CDC D2610 =LMG 10829).
Acinetobacter spp. isolates carrying the blaNDM-1 gene are frequently reported. However, most reported blaNDM-1 genes are carried by clinical strains. Here we report a carbapenem-resistant Acinetobacter towneri isolate from hospital sewage in China co-harbouring blaNDM-1 and blaOXA-58 in the genome.Whole-genome sequencing was performed using a single molecule, real-time (SMRT) sequencing platform with a Pacific Biosciences RS II Sequencer and MiSeq system. Reads were de novo assembled using Celera Assembler v.8.0. Genome annotation was performed using the NCBI Prokaryotic Genome Annotation Pipeline (PGAP), and the genome sequence was analysed by bioinformatics methods.The 2963729-bp genome with a G+C content of 41.30% displayed 11 antimicrobial resistance genes, including blaNDM-1 and blaOXA-58. Meanwhile, 2 plasmids and 19 genomic islands were predicted within the genome.The whole-genome sequence reported here can be compared with other genomes of NDM-1-producing Acinetobacter spp. These data could facilitate further understanding of the specific genomic features of carbapenem-resistant Acinetobacter spp. in China.
