Two isolates derived independently from raw refrigerated processing meat of bovine origin intended for the manufacture of Bologna-type cooked sausage could be distinguished from other known species in subsequent phylogenetic analyses. Comparison of the complete B gene sequences in combination with nearly complete 16S rRNA gene sequences revealed a separate branch within the group. In further analyses, comprising phenotypic and chemotaxonomic characterization as well as average nucleotide identity (ANI) values obtained from the draft genome assemblies, the two isolates could be distinguished from all so far published closely related species. The closest relative was DSM 3456 with ANI values of about 90.2 %. Other close neighbours were DSM 17535 (86.5 %), DSM 26521 (86.4 %), DSM 101070 (83.8 %), DSM 21104 (83.2 %), DSM 29166 (82.3 %), DSM 29165 (82.7 %) and DSM 6252 (81.9 %). The G+C contents of isolates TH39 and TH26 were both 58.2 mol%. The major cellular lipids of strain TH39 were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol; the major quinone was Q9 with small amounts of Q8. Based on these data, the isolates TH39 and TH26 (=DSM 107389=LMG 30831) represent a novel species within the genus for which the name sp. nov. is proposed. The type strain is TH39 (=DSM 107390=LMG 30830).

C19orf12 gene variants causing mitochondrial membrane protein-associated neurodegeneration (MPAN).
Eur J Hum Genet

Institute of Bioinformatics, International Technology Park, Bangalore, 560066, India.
Mitochondrial membrane protein-associated neurodegeneration (MPAN) is a rare neurodegenerative disorder characterized by spastic paraplegia, parkinsonism and psychiatric and/or behavioral symptoms caused by variants in gene encoding chromosome-19 open reading frame-12 (C19orf12). We present here seven patients from six unrelated families with detailed clinical, radiological, and genetic investigations. Childhood-onset patients predominantly had a spastic ataxic phenotype with optic atrophy, while adult-onset patients were presented with cognitive, behavioral, and parkinsonian symptoms.

There are hundreds of rare syndromic diseases involving hearing loss, many of which are not targeted for clinical genetic testing. We systematically explored the genetic causes of undiagnosed syndromic hearing loss using a combination of whole exome sequencing (WES) and a phenotype similarity search system called PubCaseFinder. Fifty-five families with syndromic hearing loss of unknown cause were analyzed using WES after prescreening of several deafness genes depending on patient clinical features.

Cancer-associated fibroblasts (CAFs) significantly influence tumor progression and therapeutic resistance in colorectal cancer (CRC). However, the distributions and functions of CAF subpopulations vary across the four consensus molecular subtypes (CMSs) of CRC. This study performed single-cell RNA and bulk RNA sequencing and revealed that myofibroblast-like CAFs (myCAFs), tumor-like CAFs (tCAFs), inflammatory CAFs (iCAFs), CXCL14CAFs, and MTCAFs are notably enriched in CMS4 compared with other CMSs of CRC.

The Mycobacterium avium complex (MAC) is a group of closely related nontuberculous mycobacteria that can cause various diseases in humans. In this study, genome sequencing, comprehensive genomic analysis, and antimicrobial susceptibility testing of 66 MAC clinical isolates from King Chulalongkorn Memorial Hospital, Bangkok, Thailand were carried out. Whole-genome average nucleotide identity (ANI) revealed the MAC species distribution, comprising 54 (81.

The relative contributions of mutation rate variation, selection, and recombination in shaping genomic variation in bacterial populations remain poorly understood. Here we analyze 3318 Yersinia pestis genomes, spanning nearly a century and including 2336 newly sequenced strains, to shed light on the patterns of genetic diversity and variation distribution at the population level. We identify 45 genomic regions ("hot regions", HRs) that, although comprising a minor fraction of the genome, are hotbeds of genetic variation.
