Immunoproteomic profiling of Rickettsia parkeri and Rickettsia amblyommii
Ticks and Tick-borne Diseases, 2015 Rickettsia parkeri is an Amblyomma-associated, spotted fever group Rickettsia species that causes an eschar-associated, febrile illness in multiple countries throughout the Western Hemisphere. Many other rickettsial species of known or uncertain pathogenicity have been detected in Amblyomma spp.

Insect Science, EarlyView.This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Frontiers in Cellular and Infection MicrobiologyJapanese 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

Brain Pathology, 1997 In this review I shall try to provide a brief, up‐to‐date, account of the neuropathology of those viral and rickettsial diseases that are particularly prevalent in tropical regions. These diseases are not, however, exclusive to the tropics. Some, such as AIDS, are common in temperate regions as well, though others are closer to being exclusively ...

Tropism and Pathogenicity of Rickettsiae [PDF]
Frontiers in Microbiology, 2012 Rickettsiae are obligate intracellular parasitic bacteria that cause febrile exanthematous illnesses such as Rocky Mountain spotted fever, Mediterranean spotted fever, epidemic, and murine typhus, etc. Although the vector ranges of each Rickettsia species are rather restricted; i.e., ticks belonging to Arachnida and lice and fleas belonging to Insecta ...

Insect Science, EarlyView.A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Molecular detection of multiple Rickettsia species in ticks from the Republic of Guinea
Ticks and Tick-Borne DiseasesTick-borne rickettsioses are emerging and re-emerging zoonotic diseases worldwide that are caused by Gram-negative bacteria of the genus Rickettsia. Ticks act as both reservoirs and vectors for these bacteria, thereby increasing opportunities for the ...

Putting Rodents at the Center of One Health Programs: A Narrative Synthesis
Integrative Zoology, EarlyView.Rodents link human, animal, and environmental health across diverse ecosystems. Rodent diversity underpins both zoonotic disease risk and ecosystem function. Environmental change reshapes rodent communities and spillover dynamics. Rodents act as reservoirs, amplifiers, and sentinels of emerging pathogens.
