Distribution and Ecological Drivers of Spotted Fever Group Rickettsia in Asia

EcoHealth, 2019
Spotted fever group and related rickettsia (SFGR) are a neglected group of pathogens that belong to the genus Rickettsia. SFGR are zoonotic and are transmitted by arthropod vectors, primarily ticks, fleas and mites to accidental hosts. These emerging and

Rickettsia-Macrophage Interactions: Host Cell Responses toRickettsia akariandRickettsia typhi [PDF]

Infection and Immunity, 2002
ABSTRACTThe 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 monocytes/macrophages may also contribute to the establishment of rickettsial infection and ...

Nanoparticle‐Based Tetracycline Delivery Systems: Advancing Therapeutic Effectiveness and Tackling Antibiotic Resistance

Particle &Particle Systems Characterization, EarlyView.
This review explores improved tetracycline (TCN) delivery via polymer‐based nanocarriers to enhance solubility, stability, and targeted release. It also covers stimuli‐responsive systems, triggered by pH, enzymes, or reactive oxygen species (ROS), and co‐delivery approaches that increase therapeutic efficacy in cancer and inflammatory diseases ...

Survey of Rickettsia species in hematophagous arthropods from endemic areas for Japanese spotted fever in China

Frontiers in Cellular and Infection Microbiology
Japanese spotted fever (JSF) is caused by Rickettsia japonica, mainly vectored by hard ticks. However, whether R. japonica can be transmitted by other arthropods remains unknown. Moreover, it is of interest to investigate whether other Rickettsia species

Wholly Rickettsia! Reconstructed Metabolic Profile of the Quintessential Bacterial Parasite of Eukaryotic Cells

mBio, 2017
Reductive genome evolution has purged many metabolic pathways from obligate intracellular Rickettsia (Alphaproteobacteria; Rickettsiaceae). While some aspects of host-dependent rickettsial metabolism have been characterized, the array of host-acquired ...

Molecular detection of pathogens in an equine fever diagnostic panel: 2019–2023

Equine Veterinary Journal, EarlyView.
Abstract Background A common diagnostic approach for febrile horses is to test for a panel of potential pathogens. Panels are curated by expert opinion and vary between diagnostic laboratories. Objectives To report the results of a newly developed equine fever diagnostic panel (EFDP) between 2019 and 2023 and evaluate the frequency of positive results.
