Molecular detection of Rickettsia felis in dogs, rodents and cat fleas in Zambia
Parasites & Vectors, 2019 Flea-borne spotted fever is a zoonosis caused by Rickettsia felis, a Gram-negative obligate intracellular bacterium. The disease has a worldwide distribution including western and eastern sub-Saharan Africa where it is associated with febrile illness in ...

Stewardship of Molecular Diagnostics in Transplant Viral Infections
Transplant Infectious Disease, EarlyView.ABSTRACT The transplant environment requires special considerations when testing for viral infections as immunosuppression results in atypical infection profiles. Microbes otherwise considered commensals or causing mild disease can lead to severe infections in transplant environments. Therefore, guidelines tend to recommend broader microbial testing in

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

Multistate Survey of American Dog Ticks (Dermacentor variabilis) for Rickettsia Species
Vector Borne and Zoonotic Diseases, 2019 Dermacentor variabilis, a common human-biting tick found throughout the eastern half and along the west coast of the United States, is a vector of multiple bacterial pathogens. Historically, D.

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.Bat ectoparasites collected from four insectivorous bat species were identified through mitochondrial gene analysis. This study provides the first evidence of bat‐associated Bartonella species in ectoparasites, including bat flies (Phthiridium sp., Raymondia sp.

Pest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.

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.

Time series model based on global structure of complete genome [PDF]
, 2000 A time series model based on the global structure of the complete genome is proposed. Three kinds of length sequences of the complete genome are considered. The correlation dimensions and Hurst exponents of the length sequences are calculated.
