Knowledge that free-living amoebae are capable of causing human disease dates back
some 50 years, prior to which time they were regarded as harmless soil organisms or, at …

Free-living amoebae are important predators that control microbial communities. They are
ubiquitous and have been isolated from various natural sources such as soil, freshwater, salt …

Throughout the natural world, organisms have responded to predators, inadequate
resources, or inclement conditions by forming ongoing mutually beneficial partnerships--or …

Background The BTB domain (also known as the POZ domain) is a versatile protein-protein
interaction motif that participates in a wide range of cellular functions, including …

Current understanding of microorganism–virus interactions, which shape the evolution and
functioning of Earth's ecosystems, is based primarily on cultivated organisms. Here we …

Diverse bacterial lineages form beneficial infections with eukaryotic hosts. The origins,
evolution, and breakdown of these mutualisms represent important evolutionary transitions …

Type 3 secretion systems (T3SSs) are essential components of two complex bacterial
machineries: the flagellum, which drives cell motility, and the non-flagellar T3SS (NF-T3SS) …

Haematopoietic and vascular cells are thought to arise from a common progenitor called the
haemangioblast. Support for this concept has been provided by embryonic stem (ES) cell …

In the rRNA-based tree of life four bacterial phyla, comprising the Planctomycetes,
Verrucomicrobia, Chlamydiae and Lentisphaerae, form together with the candidate phyla …

Genomes from all of the crucial bacterial pathogens of humans, plants and animals have
now been sequenced, as have genomes from many of the important commensal, symbiotic …
