Leptospira is a complex bacterial genus which biodiversity has long been overlooked. In the
recent years however, environmental studies have contributed to shed light on its original …

Free-living amoebae (FLA) are ubiquitous protozoa mainly found in aquatic environments.
They are well-known reservoirs and vectors for the transmission of amoeba-resistant …

Symbiotic interactions change with environmental context. Measuring these context-
dependent effects in hosts and symbionts is critical to determining the nature of symbiotic …

As predators of bacteria, amoebae select for traits that allow bacteria to become symbionts
by surviving phagocytosis and exploiting the eukaryotic intracellular environment. Soil …

The relationship between the social amoeba Dictyostelium discoideum and its
endosymbiotic bacteria Paraburkholderia provides a model system for studying the …

The social amoeba Dictyostelium discoideum is a predatory soil protist frequently used for
studying host-pathogen interactions. A subset of D. discoideum strains isolated from soil …

Some endosymbionts living within a host must modulate their hosts' immune systems in
order to infect and persist. We studied the effect of a bacterial endosymbiont on a …

The phylum Chlamydiae consists of obligate intracellular bacteria including major human
pathogens and diverse environmental representatives. Here we investigated the …

The Rhabdochlamydiaceae family is a recent addition to the Chlamydiae phylum. Its
members were discovered in cockroaches and woodlice, but recent metagenomics surveys …

Bacterial endosymbionts of the groups Wolbachia, Cardinium and Rickettsiaceae are well
known for their diverse effects on their arthropod hosts, ranging from mutualistic …
