Rickettsioses are among the oldest known infectious diseases. In spite of this, and of the
extensive research carried out, many aspects of the biology and epidemiology of tick-borne …

The genus Rickettsia encompasses 35 valid species of intracellular, coccobacilli bacteria
that can infect several eukaryotic taxa, causing multiple emerging and re-emerging diseases …

The idea that all life on earth traces back to a common origin dates back at least to Charles
Darwin's Origin of Species. Ever since, biologists have tried to piece together parts of this …

The genomic changes underlying both early and late stages of horse domestication remain
largely unknown. We examined the genomes of 14 early domestic horses from the Bronze …

Rickettsia species are endosymbionts hosted by arthropods and are known to cause mild to
fatal diseases in humans. Here, we analyse the evolution and diversity of 34 Rickettsia …

Members of the bacterial genus Rickettsia were originally identified as causative agents of
vector-borne diseases in mammals. However, many Rickettsia species are arthropod …

Reductive genome evolution has purged many metabolic pathways from obligate
intracellular Rickettsia (Alphaproteobacteria; Rickettsiaceae). While some aspects of host …

Prokaryotic genomes are often considered to be mosaics of genes that do not necessarily
share the same evolutionary history due to widespread horizontal gene transfers (HGTs) …

Many of the human infectious pathogens—especially the zoonotic or vector-borne bacteria—
are fastidious organisms that are difficult to cultivate because of their strong adaption to the …

Wolbachiae are obligate intracellular bacteria that infect arthropods and certain nematodes.
Usually maternally inherited, they may provision nutrients to (mutualism) or alter sexual …
