Complete Genome Sequences of Four Salmonella enterica Strains (Including Those of Serotypes Montevideo, Mbandaka, and Lubbock) Isolated from Peripheral Lymph Nodes of Healthy Cattle.

Salmonella enterica serotype Lubbock emerged most likely from a Salmonella enterica serotype Mbandaka ancestor that acquired by recombination the fliC operon from Salmonella enterica serotype Montevideo. Here, we report the complete genome sequence of two S. Lubbock, one S. Montevideo, and one S. Mbandaka strain isolated from bovine lymph nodes.

Complete Genome Sequence of Bradyrhizobium sp. Strain ORS3257, an Efficient Nitrogen-Fixing Bacterium Isolated from Cowpea in Senegal.

Here, we report the complete genome sequence of Bradyrhizobium sp. strain ORS3257, which forms efficient symbioses with cowpea, peanut, or groundnut. These genomic data will be useful to identify genes associated with symbiotic performance and host compatibility on several legumes, including Aeschynomene species, with which a Nod-independent type III secretion system (T3SS)-dependent symbiosis can be established.

Complete Genome Sequence of Salmonella enterica Serovar Enteritidis NCM 61, with High Potential for Biofilm Formation, Isolated from Meat-Related Sources.

Here, we report the complete genome sequence of strain NMC 61 of Salmonella enterica serovar Enteritidis, which was previously isolated from conveyor belts during chicken slaughter and has the potential to form biofilms on several surfaces. The genome is predicted to contain 110 noncoding small RNAs on the chromosome.

The Genome Sequence of M228, a Chinese Isolate of Pseudomonas syringae pv. actinidiae, Illustrates Insertion Sequence Element Mobility.

We present here the complete genome sequence of M228, a Chinese biovar 3 strain of Pseudomonas syringae pv. actinidiae, a bacterial pathogen of kiwifruit. A comparison of the insertion sequence (IS) profile of M228 with that of ICMP18708, a New Zealand isolate of P. syringae pv. actinidiae, provided insight into the evolutionary history of IS elements within biovar 3.

Complete Genome Sequences of Three Shiga Toxin-Producing Escherichia coli O111:H8 Strains Exhibiting an Aggregation Phenotype.

Non-O157 Shiga toxin-producing Escherichia coli (STEC) strains are a common source of foodborne illness. STEC O111 is among the most prevalent non-O157 STEC serogroups. Few completed genomes of STEC O111 strains have been reported to date. We report here the complete genomic sequences of three O111:H8 strains that display a distinct aggregation phenotype.

Complete Genome Sequence of Staphylococcus epidermidis CSF41498.

Staphylococcus epidermidis CSF41498 is amenable to genetic manipulation and has been used to study mechanisms of biofilm formation. We report here the whole-genome sequence of this strain, which contains 2,427 protein-coding genes and 82 RNAs within its 2,481,008-bp-long genome, as well as three plasmids.

Complete genome sequence of Nitratireductor sp. strain OM-1: A lipid-producing bacterium with potential use in wastewater treatment.

Reducing CO2 emissions is necessary to alleviate rising global temperature. Renewable sources of energy are becoming an increasingly important substitute for fossil fuels. An important step in this direction is the isolation of novel, technologically relevant microorganisms. Nitratireductor sp. strain OM-1 can convert volatile short-chain fatty acids in wastewater into 2-butenoic acid and its ester and can accumulate intracellularly esterified compounds up to 50% of its dried cell weight under nitrogen-depleted conditions. It is believed that a novel fatty acid biosynthesis pathway including an esterifying enzyme is encoded in its genome. In this study, we report the whole-genome sequence (4.8 Mb) of OM-1, which comprises a chromosome (3,977,827 bp) and a megaplasmid (857,937 bp). This sequence information provides insight into the genome organization and biochemical pathways of OM-1. In addition, we identified lipid biosynthesis pathways in OM-1, paving the way to a better understanding of its biochemical characterization.

Complete Genome Sequence of “Candidatus Thioglobus sp.” Strain NP1, an Open-Ocean Isolate from the SUP05 Clade of Marine Gammaproteobacteria

Candidatus Thioglobus sp.textquotedblright strain NP1 is an open-ocean isolate from the SUP05 clade of Gammaproteobacteria. Whole-genome comparisons of strain NP1 to other sequenced isolates from the SUP05 clade indicate that it represents a new species of SUP05 that lacks the ability to fix inorganic carbon using the Calvin-Benson-Bassham cycle.

Genome Analyses of a New Mycoplasma Species from the Scorpion Centruroides vittatus.

Arthropod Mycoplasma are little known endosymbionts in insects, primarily known as plant disease vectors. Mycoplasma in other arthropods such as arachnids are unknown. We report the first complete Mycoplasma genome sequenced, identified, and annotated from a scorpion, Centruroides vittatus, and designate it as Mycoplasma vittatus We find the genome is at least a 683,827 bp single circular chromosome with a GC content of 42.7% and with 987 protein-coding genes. The putative virulence determinants include 11 genes associated with the virulence operon associated with protein synthesis or DNA transcription and ten genes with antibiotic and toxic compound resistance. Comparative analysis revealed that the M. vittatus genome is smaller than other Mycoplasma genomes and exhibits a higher GC content. Phylogenetic analysis shows M. vittatus as part of the Hominis group of Mycoplasma As arthropod genomes accumulate, further novel Mycoplasma genomes may be identified and characterized.
