Isolation and genomic characterization of a Dehalococcoides strain suggests genomic rearrangement during culture.

We have developed and characterized a bacterial consortium that reductively dechlorinates trichloroethene to ethene. Quantitative PCR analysis for the 16S rRNA and reductive dehalogenase genes showed that the consortium is highly enriched with Dehalococcoides spp. that have two vinyl chloride reductive dehalogenase genes, bvcA and vcrA, and a trichloroethene reductive dehalogenase gene, tceA. The metagenome analysis of the consortium by the next generation sequencer SOLiD 3 Plus suggests that a Dehalococcoides sp. that is highly homologous to D. mccartyi 195 and equipped with vcrA and tceA exists in the consortium. We isolated this Dehalococcoides sp. and designated it as D. mccartyi UCH-ATV1. As the growth of D. mccartyi UCH-ATV1 is too slow under isolated conditions, we constructed a consortium by mixing D. mccartyi UCH-ATV1 with several other bacteria and performed metagenomic sequencing using the single molecule DNA sequencer PacBio RS II. We successfully determined the complete genome sequence of D. mccartyi UCH-ATV1. The strain is equipped with vcrA and tceA, but lacks bvcA. Comparison with tag sequences of SOLiD 3 Plus from the original consortium shows a few differences between the sequences. This suggests that a genome rearrangement of Dehalococcoides sp. occurred during culture.

Complete genome sequence of a Paenalcaligenes hominis strain isolated from a paraplegic patient with neurogenic bladder using single-molecule real-time sequencing technology.

The genome of Paenalcaligenes hominis, isolated from a paraplegic patient with neurogenic bladder, was sequenced with the Pacific Biosciences RSII platform. The genome size is 2.68 Mb and includes 3,096 annotated coding sequences, including genes associated with quinone cofactors, which play crucial roles in the virulence of Gram-negative bacteria.

Complete genome sequences of Mycobacterium kansasii strains isolated from rhesus macaques.

Mycobacterium kansasii is a nontuberculous mycobacterium. It causes opportunistic infections with pulmonary and extrapulmonary manifestations. We report here the complete genome sequences of two M. kansasii strains isolated from rhesus macaques. We performed genome comparisons with human and environmental isolates of M. kansasii to assess the genomic diversity of this species. Copyright © 2017 Panda et al.

Complete genome sequence of Lactobacillus casei LC5, a potential probiotics for atopic dermatitis.

Probiotics are living microorganisms providing health beneficial effect to the host (1). Probiotics have been used for the treatment or prevention of various diseases related to diarrhea (2), cho- lesterol (3) immune function (4), and inflammatory bowel disease (5). In addition, recent study also presents that probiotic bacteria in the Bifidobacterium and Lactobacillus genera are able to have therapeutic effects in the patients of psychological disorders, such as depression, anxiety, and memory (6).

Complete genome sequence of Spiroplasma citri strain R8-A2T, causal agent of stubborn disease in Citrus species.

Spiroplasma citri causes stubborn disease in Citrus spp. and diseases in other plants. Here, we report the nucleotide sequence of the 1,599,709-bp circular chromosome and two plasmids of S. citri strain R8-A2(T) This information will facilitate analyses to understand spiroplasmal pathogenicity and evolutionary adaptations to lifestyles in plants and arthropod hosts.
