The Missing Pieces: The Role of Secretion Systems in Virulence.

is likely the most common bacterial cause of gastroenteritis worldwide, responsible for millions of cases of inflammatory diarrhea characterized by severe abdominal cramps and blood in the stool. Further, infections are associated with post-infection sequelae in developed countries and malnutrition and growth-stunting in low- and middle-income countries. Despite the increasing prevalence of the disease, campylobacteriosis, and the recognition that this pathogen is a serious health threat, our understanding of pathogenesis remains incomplete.

Shared antibiotic resistance and virulence genes in Staphylococcus aureus from diverse animal hosts.

The emergence of methicillin-resistant Staphylococcus aureus (MRSA) poses an important threat in human and animal health. In this study, we ask whether resistance and virulence genes in S. aureus are homogeneously distributed or constrained by different animal hosts.

Accessory Genome Dynamics of Local and Global Populations.

is a major bacterial colonizer and opportunistic pathogen in dogs. Methicillin-resistant (MRSP) continues to emerge as a significant challenge to maintaining canine health. We sought to determine the phylogenetic relationships of across five states in the New England region of the United States and place them in a global context.

One-component order parameter in URuSi uncovered by resonant ultrasound spectroscopy and machine learning.

The unusual correlated state that emerges in URuSi below = 17.5 K is known as "hidden order" because even basic characteristics of the order parameter, such as its dimensionality (whether it has one component or two), are "hidden." We use resonant ultrasound spectroscopy to measure the symmetry-resolved elastic anomalies across .

Hidden order and beyond: an experimental-theoretical overview of the multifaceted behavior of URuSi.

This topical review describes the multitude of unconventional behaviors in the hidden order, heavy fermion, antiferromagnetic and superconducting phases of the intermetallic compound URuSi when tuned with pressure, magnetic field, and substitutions for all three elements. Such 'perturbations' result in a variety of new phases beyond the mysterious hidden order that are only now being slowly understood through a series of state-of-the-science experimentation, along with an array of novel theoretical approaches. Despite all these efforts spanning more than 30 years, hidden order (HO) remains puzzling and non-clarified, and the search continues in 2019 into a fourth decade for its final resolution.
