Validation and implementation of whole-genome sequencing-based analytical methods for molecular surveillance and relatedness analysis of complex isolates at a national reference laboratory.

Whole genome sequencing-based methodologies have become extremely relevant for the molecular surveillance of human pathogens and are being increasingly introduced into national reference laboratory services. In this study, we describe the validation and implementation of core-genome Multi-Locus Sequence Typing (cgMLST) and whole genome single-nucleotide polymorphism (wgSNP) analysis at the Irish Mycobacteria Reference Laboratory, as a replacement for Mycobacterial Interspersed Repetitive Unit-Variable Number Tandem Repeat (MIRU-VNTR) typing. Concordance of clustering, discriminatory power, and ease-of-use of both WGS analytical methods were evaluated.

The first complete mitochondrial genome data of the Afghan pika (Lagomorpha, Ochotonidae), near the type locality.

The Afghan pika (Gray, 1842) is widely distributed across the mountains of Afghanistan, Iran, Pakistan, and southwestern Turkmenistan, most often at elevations between 2,000 and 3,000 m. Here we present, for the first time, the complete mitochondrial genomes of two specimens of the nominotypical subspecies , de novo assembled from Illumina short reads of fragmented probe-enriched DNA. The lengths of the circular mitogenomes are 16,408 bp and 16,407 bp, respectively.

Speciation across biomes: Rapid diversification with reproductive isolation in the Australian delicate mice.

Phylogeographic studies of continental clades, especially when combined with palaeoclimate modelling, provide powerful insight into how environment drives speciation across climatic contexts. Australia, a continent characterized by disparate modern biomes and dynamic climate change, provides diverse opportunity to reconstruct the impact of past and present environments on diversification. Here, we use genomic-scale data (1310 exons and whole mitogenomes from 111 samples) to investigate Pleistocene diversification, cryptic diversity, and secondary contact in the Australian delicate mice (Hydromyini: Pseudomys), a recent radiation spanning almost all Australian environments.
