Bacillus cereus is an opportunistic human pathogen causing food-borne gastrointestinal infections and non-gastrointestinal infections worldwide. The strain B. cereus FORC_013 was isolated from fried eel. Its genome was completely sequenced by PacBio technology, analyzed and compared with other complete genome sequences of Bacillus to elucidate the distinct pathogenic features of the strain isolated in South Korea. Genomic analysis revealed pathogenesis and host immune evasion-associated genes encoding tissue-destructive exoenzymes, and pore-forming toxins. In particular, tissue-destructive (hemolysin BL, nonhaemolytic enterotoxins) and cytolytic proteins (cytolysin) were observed in the genome, which damage the plasma membrane of the epithelial cells of the small intestine…
Members of the genus Humibacter, from the family Microbacteriaceae, have been isolated from sewage sludge compost, agarwood chips, and various soil samples. Here, we report the complete genome sequence of Humibacter aquilariae BT305, the first genome sequence identified within the genus Humibacter, which was isolated from the small intestine of castrated beef cattle.
We present a high-quality de novo genome assembly (rheMacS) of the Chinese rhesus macaque (Macaca mulatta) using long-read sequencing and multiplatform scaffolding approaches. Compared to the current Indian rhesus macaque reference genome (rheMac8), rheMacS increases sequence contiguity 75-fold, closing 21,940 of the remaining assembly gaps (60.8 Mbp). We improve gene annotation by generating more than two million full-length transcripts from ten different tissues by long-read RNA sequencing. We sequence resolve 53,916 structural variants (96% novel) and identify 17,000 ape-specific structural variants (ASSVs) based on comparison to ape genomes. Many ASSVs map within ChIP-seq predicted enhancer regions where apes and macaque…
Bacillus subtilis is recognized as a safe and reliable human and animal probiotic and is associated with bioactivities such as production of vitamin and immune stimulation. Additionally, it has great potential to be used as an alternative to antimicrobial drugs, which is significant in the context of antibiotic abuse in food animal production. In this study, we isolated one strain of B. subtilis, named WS-1, from apparently healthy pigs growing with sick cohorts on one Escherichia coli endemic commercial pig farm in Guangdong, China. WS-1 can strongly inhibit the growth of pathogenic E. coli in vitro. The B. subtilis strain…
Our understanding of the pig transcriptome is limited. RNA transcript diversity among nine tissues was assessed using poly(A) selected single-molecule long-read isoform sequencing (Iso-seq) and Illumina RNA sequencing (RNA-seq) from a single White cross-bred pig. Across tissues, a total of 67,746 unique transcripts were observed, including 60.5% predicted protein-coding, 36.2% long non-coding RNA and 3.3% nonsense-mediated decay transcripts. On average, 90% of the splice junctions were supported by RNA-seq within tissue. A large proportion (80%) represented novel transcripts, mostly produced by known protein-coding genes (70%), while 17% corresponded to novel genes. On average, four transcripts per known gene (tpg) were…
