Invasive Staphylococcus aureus infections are common, causing high mortality,
compounded by the propensity of the bacterium to develop drug resistance. S. aureus is an …

Whether the human fetus and the prenatal intrauterine environment (amniotic fluid and
placenta) are stably colonized by microbial communities in a healthy pregnancy remains a …

The discovery of antibiotics more than 80 years ago has led to considerable improvements
in human and animal health. Although antibiotic resistance in environmental bacteria is …

Microbial genes encode the majority of the functional repertoire of life on earth. However,
despite increasing efforts in metagenomic sequencing of various habitats,–, little is known …

Staphylococcus aureus is a leading cause of bovine mastitis worldwide. Despite some
improved understanding of disease pathogenesis, progress towards new methods for the …

Mobile genetic elements are key to the evolution of bacteria and traits that affect host and
ecosystem health. Here, we use a framework of a hierarchical and modular system that …

Cyanobacteria are photosynthetic prokaryotes that inhabit diverse aquatic and terrestrial
environments. However, the evolutionary mechanisms involved in the cyanobacterial habitat …

Evolution is the hallmark of life. Descriptions of the evolution of microorganisms have
provided a wealth of information, but knowledge regarding “what happened” has precluded …

Staphylococcus aureus is a mammalian commensal and opportunistic pathogen that
colonizes niches such as skin, nares and diverse mucosal membranes of about 20-30% of …

Enterococcus faecalis is a commensal and nosocomial pathogen, which is also ubiquitous
in animals and insects, representing a classical generalist microorganism. Here, we study E …
