Characterization of a colistin resistant, hypervirulent hospital isolate of Acinetobacter courvalinii from Canada.

Non-baumannii Acinetobacter spp. are becoming more prevalent in clinical settings including those that present resistance to last-resort antibiotics such as colistin. AB222-IK40 is an Acinetobacter courvalinii strain isolated from the Ottawa Hospital Research Institute located in Ottawa, Canada.

sections : New genomic resources, phylogenomic analyses, and biodiversity.

Species in sections and are commonly isolated from agricultural crops and a variety of other plant hosts. With the increasing appreciation that species from these two sections are often the dominant taxa recovered from important cereal crops, the need for improved understanding of their biodiversity and taxonomy has grown. Given that morphological characteristics and existing molecular markers are not sufficient for distinguishing among species, we expanded the genomic resources for these sections to support research in biosystematics and species diagnostics.

Phylogenomic and phenotypic analyses highlight the diversity of antibiotic resistance and virulence in both human and non-human .

is a Gram-negative, opportunistic pathogen that causes infections in the immunocompromised. With a high incidence of muti-drug resistance, carbapenem-resistant is designated as a priority 1 pathogen by the WHO. The current literature has expertly characterized clinical isolates of .

Emergence of ADC-5 Cephalosporinase in environmental from a German tank milk with a novel Sequence Type.

Bacteria resistant to antibiotics arguably pose the greatest threat to human health in the twenty-first century. One such bacterium that typifies antibiotic resistance is . Frequently, hospital strains of display multidrug resistant (MDR) or extensively drug resistant (XDR) phenotypes, often requiring the use of last resort antibiotics for treatment.

Draft Genome Sequence of sp. Strain CaF467b, Isolated from a Pig Manure Storage Tank.

In this report, we present the draft genome sequence of an unclassified strain, CaF467b. This bacterial isolate was recovered from a pig manure storage tank. The draft genome sequence is 1,655,514 bp in length with 1,709 predicted genes and a G+C content of 34.

Autophosphorylation Inhibits RcCDPK1, a Dual-Specificity Kinase that Phosphorylates Bacterial-Type Phosphoenolpyruvate Carboxylase in Castor Oil Seeds.

Phosphoenolpyruvate carboxylase (PEPC) is a tightly regulated enzyme that plays a crucial anaplerotic role in central plant metabolism. Bacterial-type PEPC (BTPC) of developing castor oil seeds (COS) is highly expressed as a catalytic and regulatory subunit of a novel Class-2 PEPC heteromeric complex. Ricinus communis Ca2+-dependent protein kinase-1 (RcCDPK1) catalyzes in vivo inhibitory phosphorylation of COS BTPC at Ser451.

Whole-Genome Resources and Species-Level Taxonomic Validation of 89 Plant-Pathogenic Strains Isolated from Various Host Plants.

Bacterial spot disease caused by s spp. is a global threat to tomato and pepper plants. A recent classification of these pathogens indicated the need for a diverse dataset of whole-genome resources.

Analysis of Draft Genome Sequences of Two New Strains Associated with Wheat Leaf Necrotic Tissues Caused by Xanthomonas translucens Reveals Distinct Species.

We report whole-genome sequences of two new strains (DOAB1048 and DOAB1050) isolated from necrotic wheat leaves caused by The draft genome sequences of DOAB1048 and DOAB1050 consist of 52 and 57 scaffolds and have sizes of 4,795,525 bp and 4,962,883 bp with 4,418 and 4,517 coding sequences, respectively.

The calcium-dependent protein kinase RcCDPK2 phosphorylates sucrose synthase at Ser11 in developing castor oil seeds.

Imported sucrose is cleaved by sucrose synthase (SUS) as a critical initial reaction in the biosynthesis of storage end-products by developing seeds. Although SUS is phosphorylated at a conserved seryl residue by an apparent CDPK (Ca-dependent protein kinase) in diverse plant tissues, the functions and mechanistic details of this process remain obscure. Thus, the native CDPK that phosphorylates RcSUS1 (Ricinus communis SUS1) at Ser in developing COS (castor oil seeds) was highly purified and identified as RcCDPK2 by MS/MS.
