Complete genome sequence of a novel alternavirus infecting Fusarium falciforme.

We present the complete genome sequence of a novel alternavirus, tentatively named "Fusarium falciforme alternavirus 1 (FfAV1)", isolated from Fusarium falciforme. The host, F. falciforme strain Fod375, was isolated from a soil sample in Spain in 2012 and was found to be infected with a virus containing a tetra-segmented double-stranded (ds) RNA genome. The genome segments, designated as dsRNA1 (3529 bp), dsRNA2 (2641 bp), dsRNA3 (2459 bp), and dsRNA4 (1471 bp), each possess a single open reading frame (ORF). The protein predicted from dsRNA1 contains the typical domains of an RNA-dependent RNA polymerase (RdRP) homologous to those of previously reported alternaviruses, while the protein predicted from dsRNA3 shows homology to alternavirus capsid proteins. The proteins encoded by dsRNA2 and dsRNA4 are of unknown function. All predicted proteins exhibited the highest sequence identity with their counterparts in Hebei alternavirus and Marquandomyces marquandii alternavirus 1. Phylogenetic analysis supported the placement of this FfAV1 isolate within the genus Alternavirus. Considering these results, we propose that FfAV1, along with the two closely related unassigned alternaviruses, represents a new species within the genus.

Complete genome sequence of Streptococcus vaginalis strain UMB8616 isolated from the bladder of a female with urge urinary incontinence.

Streptococcus vaginalis is a recently identified bacterial species closely related to Streptococcus anginosus. It has been isolated from the human urogenital tract. We report the complete genome sequence of S. vaginalis UMB8616 (=ATCC TSD-371 = CCUG 77169 = DSM 115471) isolated from the bladder of a human female with urge urinary incontinence.

Complete genome sequences of three co-occurring Pseudomonas isolates from California Botanic Garden topsoil.

We report the complete genome sequences of three Pseudomonas isolates recovered from topsoil at the California Botanic Garden. Two isolates share ~99.4% average nucleotide identity, enabling investigation of intraspecies microvariation; the third represents a co-occurring distinct species, together capturing species- and strain-level genomic diversity within a natural soil community.

Coding-complete genome sequence of grapevine leafroll-associated virus 13 from grapevine in California.

In this study, we report the coding-complete genome sequence of Grapevine leafroll-associated virus 13 (GLRaV-13), isolate CA8881, detected in Vitis vinifera in California, USA. The genome sequence exhibited over 95% nucleotide identity with previously reported GLRaV-13 isolates and contributed to better understanding of the genetic diversity of ampeloviruses infecting grapevine.

Complete genome sequence of Rhodococcus qingshengii strain A3-8.

A chemostat culture was constructed with phenol and forest soil as an inoculum. We report the complete genome sequence of Rhodococcus qingshengii strain A3-8, which was isolated from the culture. The genome consists of a chromosome (6,436,695 bp) and a linear plasmid pA38 (257,365 bp).

Complete genome sequence of multidrug-resistant Salmonella enterica subsp. enterica serovar Enteritidis SD191 isolated from chicken liver, harboring a novel imipenem resistance mechanism.

We present the complete genome sequence of Salmonella enterica subsp. enterica serovar Enteritidis SD191 isolated from Gallus gallus liver in China, harboring plasmid pSE191. The genome reveals multiple antibiotic resistance mechanisms and phenotypic imipenem resistance without canonical genes.

Complete genome of multiply antibiotic resistant ST10 Acinetobacter baumannii isolate NL6 from Vietnam and relationship to available ST10 genomes.

The genome of NL6, a multiply antibiotic-resistant Acinetobacter baumannii ST10:KL49:OCL2 carriage isolate from Vietnam, was sequenced using Nanopore technology, and complete chromosome and plasmid sequences were assembled from the long reads and available short reads. Resistance genes and their locations were identified, and transfer of a conjugative plasmid carrying several resistance genes into a new host was tested. The acquired resistance genes in NL6 were distributed between the chromosome and two of three plasmids present. The chromosome carries multiple copies of several insertion sequences, an incomplete copy of the ISAba1-bounded Tn6250 that includes the sul2 and strAB genes, and an integrative element carrying copper resistance genes designated IECuR. Plasmid pNL6-2 (r3-T5; 15 Kbp) is a Rep_3/OrfX plasmid that includes a tet39 dif module, and pNL6-3 (r3-T20; 66.9 Kbp) carries aacC2d, aphA6, and blaCARB-16 and a second ampC gene preceded by an ISAba1. Conjugation of pNL6-3 into derivatives of ATCC17978 was demonstrated, confirming that the ampC gene confers resistance to third-generation cephalosporins. NL6 was compared to other complete ST10 genomes. Several acquired elements in the chromosome were shared with the ST10 isolate LAC-4 (USA), indicating shared ancestry, but the plasmid content differed. The KL and plasmid content were variable in 17 further complete ST10 genomes downloaded from GenBank. Tn6250 and IECuR were only found together in the chromosome of two further KL49 isolates. Antibiotic resistance in ST10 A. baumannii was acquired mainly via plasmid acquisition, but resistance genes varied, and a variety of plasmids was involved.IMPORTANCEMembers of the CC10 clonal complex of Acinetobacter baumannii comprising ST10 plus single and double locus variants are known to be particularly virulent. However, antibiotic resistance in members of this group has rarely been examined. Here, determination of the complete genome (chromosome and plasmids) of a representative ST10 isolate from Vietnam allowed the context and location of acquired antibiotic resistance genes and of other mobile genetic elements to be determined. Mobile genetic element locations in completed chromosomes facilitate comparisons of potentially related genomes, revealing those with recent shared ancestry. Differences in plasmid content can also be examined.
