As a leading cause of bacterial-derived gastroenteritis worldwide, Campylobacter has a significant impact on human health. In the developed world, most campylobacteriosis cases are attributed to the consumption of undercooked, contaminated poultry; however, it has been shown that Campylobacter can be transmitted to humans through contaminated water and other types of food, including beef and milk. As such, high-resolution microbial source-tracking is essential for health department officials to determine the source(s) of Campylobacter outbreaks. For these reasons, this protocol provides the techniques needed for isolation of Campylobacter from agricultural and environmental sources, as well as human clinical specimens. Additionally, we describe a simple method for preparing high-quality genomic DNA that can be used for whole-genome sequencing and downstream bioinformatics analyses of Campylobacter genotypes. © 2018 by John Wiley & Sons, Inc.

Sauvagesia rhodoleuca is an endangered species endemic to southern China. Due to human activities, only six fragmented populations remain in Guangdong and Guangxi. Despite considerable conservation efforts, its demographic history and evolution remain poorly understood, particularly from a genomic perspective.

Background: Although blood group variation was first described over a century ago, our understanding of the genetic variation affecting antigenic expression on the red blood cell surface in many populations is lacking. This deficit limits the ability to accurately type patients, especially as serological testing is not available for all described blood groups, and targeted genotyping panels may lack rare or population-specific variants.
Study Design And Methods: Here, we perform serological assays across 24 antigens and whole genome sequencing on 100 Omanis, a population underrepresented in genomic databases.

Introduction: Typhoid fever, caused by Salmonella Typhi and Paratyphi, remains a sig-nificant public health concern, particularly in developing countries. The emergence of antimicrobial resistance, including resistance to first-line drugs, fluoroquinolones, and the development of re-sistance to ceftriaxone, poses a significant threat to effective treatment.
Methods: This study investigated extended-spectrum β-lactamase (ESBL)-producing Salmonella Typhi isolates from blood samples of patients with suspected typhoid fever at a tertiary care hospital in Western Rajasthan, India, between April 2022 and May 2024.

Listeria: Biology and Infection Research Group (LisBio), Valencia, Spain.
Listeria monocytogenes is a saprophytic bacterium and a foodborne pathogen of humans and animals. Little is known about its distribution and genetic diversity across different environments within the same geographical region. We conducted a large-scale longitudinal study in southeastern Spain monitoring Listeria spp.

Here, using whole-exome sequencing of a cohort of 17 Japanese patients with 46,XY disorders or differences of sex development, we identified two pathogenic DEAH-box helicase 37 (DHX37) variants in three patients. We also identified a patient with a likely pathogenic variant in SOX9 and a rare likely benign variant in DHX37. This Data Report highlights the genetic and phenotypic diversity of DXH37 variants.
