Recent development of long-read sequencing platforms has enabled researchers to explore bacterial community structure through analysis of full-length 16S rRNA gene (∼1,500 bp) or 16S-ITS-23S rRNA operon region (∼4,300 bp), resulting in higher taxonomic resolution than short-read sequencing platforms. Despite the potential of long-read sequencing in metagenomics, resources and protocols for this technology are scarce. Here, we describe MIrROR, the database and analysis tool for metataxonomics using the bacterial 16S-ITS-23S rRNA operon region.

In this study, the first complete genome of was constructed using a cost-effective long-read sequencing platform, Flongle from Oxford Nanopore, and comparative genome analysis was conducted using a total of 1,046 strain genomes from 10 vaginal species. Single-molecule sequencing using Flongle effectively resolved the limitation of the 2nd generation sequencing technologies in dealing with genomic regions of high GC contents, and comparative genome analysis identified three potential core genes (INY, ZnuA, and ) of which was related to its specific adaption to the vaginal environment.

The incidence of avian NE has been progressively increasing following the removal of antibiotics from poultry feed. We evaluated the effect of diets supplemented with the thermally-processed clays, calcium montmorillonite (CaMM) on clinical signs, immunopathology, and cytokine responses in broiler chickens using an experimental model of NE consisting of co-infection with and .
View Article and Find Full Text PDFTumor necrosis factor-like ligand 1A (TL1A) is a type II transmembrane protein predominantly expressed by endothelial cells that promotes the expansion of activated T cells and regulatory T cells, modulates inflammation, and regulates the production of a wide variety of T cell cytokines. However, there have not been any mAbs which specifically detect chTL1A and define its biochemical and immunological properties. So in this study, two mouse monoclonal antibodies (mAbs) which specifically detect chicken TL1A (chTL1A) were developed and characterized.
