Honey bee, Apis mellifera, drones are typically haploid, developing from an unfertilized egg, inheriting only their queen's alleles and none from the many drones she mated with. Thus the ordered combination or 'phase' of alleles is known, making drones a valuable haplotype resource. We collated whole-genome sequence data for 1,407 drones, including 45 newly sequenced Scottish drones, collectively representing 19 countries, 8 subspecies and various hybrids. Following alignment to Amel_HAv3.1, variant calling and quality filtering, we retained 17.4 M high quality variants across 1,328 samples with a genotyping rate of 98.7%. We demonstrate the utility of this haplotype resource, AmelHap, for genotype imputation, returning >95% concordance when up to 61% of data is missing in haploids and up to 12% of data is missing in diploids. AmelHap will serve as a useful resource for the community for imputation from low-depth sequencing or SNP chip data, accurate phasing of diploids for association studies, and as a comprehensive reference panel for population genetic and evolutionary analyses.

The Thorny Skate (Amblyraja radiata) is a vulnerable species displaying a discrete size-polymorphism in the northwest Atlantic Ocean (NWA). We conducted whole genome sequencing of samples collected across its range. Genetic diversity was similar at all sampled sites, but we discovered a ~ 31 megabase bi-allelic supergene associated with the size polymorphism, with the larger size allele having introgressed in the last ~160,000 years B.

Objectives: Emerging human pathogens of animal origin have become an increasing public health concern in recent years. The aim of this study was to investigate the transmission of group B streptococcus (GBS) clonal complex (CC) 61 strains in the southern Chinese population and analyze their genetic characteristics.
Methods: Whole-genome sequencing was performed on 693 clinical isolates of GBS collected from southern China between 2016 and 2021, and the prevalence of human CC61 isolates was investigated by genomic epidemiology.
Benzo (a) pyrene produced by food during high-temperature process enters the body through ingestion, which causes food safety issues to the human body. In order to alleviate the harm of foodborne benzo (a) pyrene to human health, a strain that can degrade benzo (a) pyrene was screened from Kefir, a traditional fermented product in Xinjiang. Bacillus cereus M72-4 is a Gram-positive bacteria sourced from Xinjiang traditional fermented product Kefir, under Benzo(a)pyrene stress conditions, there was 69.

Introduction: The methicillin-resistant Staphylococcus aureus (MRSA) genome varies by geographical location. This study aims to determine the genomic characteristics of MRSA using whole-genome sequencing (WGS) data from medical centers in Mexico and to explore the associations between antimicrobial resistance genes and virulence factors.
Methods: This study included 27 clinical isolates collected from sterile sites at eight centers in Mexico in 2022 and 2023.
