Amblyomma imitator Ticks as Vectors of Rickettsia rickettsii, Mexico

Emerging Infectious Diseases, 2010
Real-time PCR of Amblyomma imitator tick egg masses obtained in Nuevo Leon State, Mexico, identified a Rickettsia species. Sequence analyses of 17-kD common antigen and outer membrane protein A and B gene fragments showed to it to be R. rickettsii, which

Diversity of Anaplasma phagocytophilum Strains, USA

Emerging Infectious Diseases, 2009
We analyzed the structure of the expression site encoding the immunoprotective protein MSP2/P44 from multiple Anaplasma phagocytophilum strains in the United States. The sequence of p44ESup1 had diverged in Ap-variant 1 strains infecting ruminants.

Rickettsia parkeriin Brazil

Emerging Infectious Diseases, 2007
We report finding Rickettsia parkeri in Brazil in 9.7% of Amblyomma triste ticks examined. An R. parkeri isolate was successfully established in Vero cell culture. Molecular characterization of the agent was performed by DNA sequencing of portions of the rickettsial genes gltA, htrA, ompA, and ompB.

Diversity of Rickettsia species in border regions of northwestern China

Parasites & Vectors, 2018
Rickettsia species belonging to the spotted fever group (SFG) cause infections in humans, domestic animals and wildlife. At least ten SFG Rickettsia species are known to occur in China.

Curvature and torsion in growing actin networks

, 2007
Intracellular pathogens such as Listeria monocytogenes and Rickettsia rickettsii move within a host cell by polymerizing a comet-tail of actin fibers that ultimately pushes the cell forward.

Prevalence and diversity of Rickettsia species in ectoparasites collected from small rodents in Lithuania

Parasites & Vectors, 2018
Rickettsiae are emerging pathogens causing public health problems in many countries around the world. Rickettsia spp. are found in association with a wide range of arthropods which feed on different species of animals.

Effects of Rickettsia amblyommatis Infection on the Vector Competence of Amblyomma americanum Ticks for Rickettsia rickettsii.

Vector Borne and Zoonotic Diseases, 2018
Although Dermacentor spp. ticks are considered the primary vectors of Rickettsia rickettsii in the United States, other North American tick species are also capable of transmitting the agent, including the lone star tick-Amblyomma americanum.
