Recent discoveries of basal extracellular Rickettsiales have illuminated divergent
evolutionary paths to host dependency in later-evolving lineages. Family Rickettsiaceae …

Rickettsiae include diverse Gram-negative microbial species that exhibit obligatory
intracellular lifecycles between mammalian hosts and arthropod vectors. Human infections …

Pathogenic bacteria secrete protein effectors to hijack host machinery and remodel their
infectious niche. Rickettsia spp. are obligate intracellular bacteria that can cause life …

Alpha‐solenoids are a significant and diverse subset of structured tandem repeat proteins
(STRPs) that are important in various domains of life. This review examines their structural …

While fleas are often perceived simply as a biting nuisance and a cause of allergic
dermatitis, they represent important disease vectors worldwide, especially for bacterial …

Ankyrin repeat is a 33-amino acid motif commonly observed in eukaryotes and, to a lesser
extent, in prokaryotes and archaea and rarely in viruses. This motif plays a crucial role in …

Blumeria graminis f. sp. tritici (Bgt) is a globally important fungal wheat pathogen. Some
wheat genotypes contain powdery mildew resistance (Pm) genes encoding immune …

Intracellular bacteria use secreted effector proteins to modify host biology and facilitate
infection. For many of these microbes, a particular eukaryotic domain—the ankyrin repeat …

Leptospira is a genus of bacteria that includes free-living saprophytic species found in water
or soil, and pathogenic species, which are the etiologic agents of leptospirosis. Besides all …

While fleas are often perceived simply as a biting nuisance and cause of allergic dermatitis,
they represent important disease vectors worldwide, especially for bacterial zoonoses such …
