A Three-Dimensional Technique for The Visualization of Mitochondrial Ultrastructural Changes in Pancreatic Cancer Cells.

Understanding the dynamic features of the cell organelle ultrastructure, which is not only rich in unknown information but also sophisticated from a three-dimensional (3D) perspective, is critical for mechanistic studies. Electron microscopy (EM) offers good imaging depth and allows for the reconstruction of high-resolution image stacks to investigate the ultrastructural morphology of cellular organelles even at the nanometer scale; therefore, 3D reconstruction is gaining importance due to its incomparable advantages. Scanning electron microscopy (SEM) provides a high-throughput image acquisition technology that allows for reconstructing large structures in 3D from the same region of interest in consecutive slices.

Genome Resource of L9-754, an Endophyte Isolated From Leaf Tissues of .

strain L9-754 (DSM 27347) is a gram-negative, chemoheterotrophic, and rod-shaped endophyte isolated from the stem tissues of L. This strain has putative in vitro antagonistic ability against the plant pathogenic fungus . A draft genome of L9-754T was obtained using the PacBio SMRT cell platform.

Complete genome sequence of Achromobacter spanius type strain DSM 23806, a pathogen isolated from human blood.

Objectives: Achromobacter spanius is a newly described, non-fermenting, Gram-negative, coccoid pathogen isolated from human blood. Whole-genome sequencing of the A. spanius type strain was performed to investigate the mechanism of pathogenesis of this strain at a genomic level.

Complete genome sequence of Achromobacter insolitus type strain LMG 6003T, a pathogen isolated from leg wound.

Achromobacter insolitus is a newly described, Gram-negative, small (1-2 mm long) and coccoid pathogen that has been isolated from leg wound. Due to its potential threat to human beings, the type strain of this species LMG 6003T was completely sequenced in this study. The genomic analysis revealed that the genome of LMG 6003T consists of one circular DNA chromosome of 6 492 697 bp with a GC content of 65.

Emerging of two new subgenotypes of porcine reproductive and respiratory syndrome viruses in Southeast China.

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the leading swine pathogens and causes major economic loss to the global swine industry. In this study, a total of 49 PRRSV isolates were collected from different swine herds in seven provinces in Southeast China from 2014 to 2015. All the ORF5 genes and some Nsp2 genes were sequenced.
