Companion animals are likely relevant in the transmission of antimicrobial-resistant bacteria. sequence type 171 (ST171), a clone that has been implicated in clusters of infections in humans, was isolated from two dogs with clinical disease in Ohio. The canine isolates contained IncHI2 plasmids encoding Whole-genome sequencing was used to put the canine isolates in phylogenetic context with available human ST171 sequences, as well as to characterize their plasmids.

Marthamycetales species are widely distributed, non-lichenized, apothecial ascomycetes that are associated with various woody plants and grasses. Most species are presumed to be saprobes, although a few are pathogens. Apothecia are small and erumpent, with farinose discs that are encircled by ragged, projecting flaps of degraded plant tissue.

Cell type-specific regulatory programs that drive type 1 diabetes (T1D) in the pancreas are poorly understood. Here, we performed single-nucleus multiomics and spatial transcriptomics in up to 32 nondiabetic (ND), autoantibody-positive (AAB), and T1D pancreas donors. Genomic profiles from 853,005 cells mapped to 12 pancreatic cell types, including multiple exocrine subtypes.

Breastfeeding is essential for reducing infant morbidity and mortality, yet exclusive breastfeeding rates remain low, often because of insufficient milk production. The molecular causes of low milk production are not well understood. Fresh milk samples from 30 lactating individuals, classified by milk production levels across postpartum stages, were analyzed using genomic and microbiome techniques.

Somatic mitochondrial DNA (mtDNA) mutations are frequently observed in tumors, yet their role in pediatric cancers remains poorly understood. The heteroplasmic nature of mtDNA-where mutant and wild-type mtDNA coexist-complicates efforts to define its contribution to disease progression. In this study, bulk whole-genome sequencing of 637 matched tumor-normal samples from the Pediatric Cancer Genome Project revealed an enrichment of functionally impactful mtDNA variants in specific pediatric leukemia subtypes.

The nitrogen-fixing, chemolithoautotrophic genus is found across numerous diverse environments worldwide and is an important member of many ecosystems. These species serve as model systems for their metabolic properties and have industrial applications in bioremediation and sustainable protein, food and fertilizer production. Despite their abundance and utility, the majority of strains are without a genome sequence, and only eight validly published species are known to date.
