Borrelia burgdorferi is the causative agent of Lyme disease and is transmitted to vertebrate
hosts by Ixodes spp. ticks. The spirochaete relies heavily on its arthropod host for basic …

The intracellular pathogen Anaplasma marginale (Rickettsiales: Anaplasmataceae),
described by Sir Arnold Theiler in 1910, is endemic worldwide in tropical and subtropical …

Ticks transmit more pathogens to humans and animals than any other arthropod. We
describe the 2.1 Gbp nuclear genome of the tick, Ixodes scapularis (Say), which vectors …

SUMMARY A large amount of knowledge has been acquired since the original descriptions

Anaplasmosis, a tick-borne cattle disease caused by the rickettsia Anaplasma marginale, is
endemic in tropical and subtropical areas of the world. The disease causes considerable …

The tick-borne intracellular pathogen Anaplasma marginale (Rickettsiales:
Anaplasmataceae) develops persistent infections in cattle and tick hosts. While erythrocytes …

The presence, internal distribution, and phylogenetic position of endosymbiotic bacteria from
four species of specific-pathogen-free ticks were studied. These included the hard ticks …

Background human granulocytic ehrlichiosis is a potentially fatal tick-borne infection that has
recently been described. This acute febrile illness is characterized by myalgias, headache …

We describe the isolation and characterization of Rickettsia monacensis sp. nov.(type strain,
IrR/MunichT) from an Ixodes ricinus tick collected in a city park, the English Garden in …

The causative agent of human granulocytic ehrlichiosis was recently reclassified as
Anaplasma phagocytophilum, unifying previously described bacteria that cause disease in …
