Ticks are among the most important vectors of pathogens affecting humans and other
animals worldwide. They do not only carry pathogens however, as a diverse group of …

For over 300 million years, insects have relied on symbiotic microbes for nutrition and
defence. However, it is unclear whether specific ecological conditions have repeatedly …

Ecological specialization to restricted diet niches is driven by obligate, and often maternally
inherited, symbionts in many arthropod lineages. These heritable symbionts typically form …

ABSTRACT The family “Candidatus Midichloriaceae” constitutes the most diverse but least
studied lineage within the important order of intracellular bacteria Rickettsiales.“Candidatus …

We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks
between subspecies and class, proposed between the mid-1990s, when the provisional …

Bacterial symbionts are integral to the health and homeostasis of invertebrate hosts.
Notably, members of the Rickettsiales genus Wolbachia influence several aspects of the …

Populations of key benthic habitat-forming octocoral species have declined significantly in
the Mediterranean Sea due to mass mortality events caused by microbial disease outbreaks …

Ticks are one of the most important blood-sucking vectors for infectious microorganisms in
humans and animals. When feeding they inject saliva, containing microbes, into the host to …

ABSTRACT “Candidatus Midichloria mitochondrii” is an intramitochondrial bacterium of the
order Rickettsiales associated with the sheep tick Ixodes ricinus. Bacteria phylogenetically …

Rickettsiales are a lineage of obligate intracellular Alphaproteobacteria, encompassing
important human pathogens, manipulators of host reproduction, and mutualists. Here we …
