Rickettsia -Macrophage Interactions: Host Cell Responses to Rickettsia akari and Rickettsia typhi [PDF]

Infection and Immunity, 2002
The existence of intracellular rickettsiae requires entry, survival, and replication in the eukaryotic host cells and exit to initiate new infection. While endothelial cells are the preferred target cells for most pathogenic rickettsiae, infection of ...

Oral Flea Preventive to Control Rickettsia typhi–Infected Fleas on Reservoir Opossums, Galveston, Texas, USA, 2023–2024 [PDF]

Emerging Infectious Diseases
Murine typhus, a fleaborne bacterial disease caused by Rickettsia typhi, has reemerged and spread in the United States. We tested spinosad, an oral flea preventive, in opossum flea reservoirs. Spinosad killed 98% of fleas infesting opossums.

Autophagy facilitates intracellular survival of pathogenic rickettsiae in macrophages via evasion of autophagosomal maturation and reduction of microbicidal pro-inflammatory IL-1 cytokine responses

Microbiology Spectrum, 2023
The genus Rickettsia is comprised of obligate intracellular bacterial parasites of a wide range of arthropod and vertebrate hosts. Some Rickettsia species (spp.) are responsible for serious human diseases globally.
