Detection and characterization of rickettsiae in Western Australia

, 2007
The aim of this study was to address the shortfall in current, in-depth knowledge of Western Australian rickettsiae investigating in particular, the role of native and feral animals as reservoir hosts.

Experimental infection with Rickettsia rickettsii in an Amblyomma dubitatum tick colony, naturally infected by Rickettsia bellii

Ticks and Tick-borne Diseases, 2014
Amblyomma dubitatum engorged females, naturally infected by Rickettsia bellii, were used to establish a laboratory colony. Larvae, nymphs, and adults were exposed to two strains of Rickettsia rickettsii by feeding on needle-inoculated guinea pigs, and thereafter reared on uninfected guinea pigs.

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that precedes the transmission of many tick‐borne pathogens ...

Acute Disseminated Encephalomyelitis Presenting as Fever of Unknown Origin in a 4‐Year‐Old Boy: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT A 4‐year‐old boy presented with prolonged fever of unknown origin and systemic inflammation without early neurological signs. MRI revealed multifocal demyelination, and MOG antibodies were positive. He was diagnosed with ADEM and treated with steroids and IVIg, but relapsed twice, consistent with multiphasic disseminated encephalomyelitis ...

Rickettsiales and rickettsial diseases in Australia

, 2010
Currently, there are 12 known Rickettsiales species in Australia. However research into the diversity and range of these agents in Australia is still far from complete.

Infection Potential of Rickettsia felis via Ingestion

, 2019
Rickettsia felis is the etiologic agent of flea-borne spotted fever (FBSF) in humans and a poorly described cause of fever in animals. It is transmitted by its primary arthropod vector and reservoir host, the cat flea Ctenocephalides felis.

Ankyrin repeat domain-encoding genes in the wPip strain of Wolbachia from the Culex pipiens group [PDF]

, 2007
BACKGROUND: Wolbachia are obligate endosymbiotic bacteria maternally transmitted through the egg cytoplasm that are responsible for several reproductive disorders in their insect hosts, such as cytoplasmic incompatibility (CI) in infected mosquitoes ...

Pathways of Protein Secretion in Prokaryotes and Eukaryotes: Molecular Mechanisms, Biological Functions, and Therapeutic Opportunities

MedComm, Volume 7, Issue 6, June 2026.
This graphical abstract delineates noncanonical protein secretion systems across eukaryotes and prokaryotes. Eukaryotic UcPS covers four ER–Golgi bypass pathways, enabling rapid leaderless protein export via direct transmembrane translocation or vesicle‐mediated release.

Ehrlichia, Anaplasma, and Rickettsia

, 2016
Rickettsia, Ehrlichia, and Anaplasma are infections primarily transmitted by ticks (but, in the case of certain Rickettsial species, are transmitted by other vectors as well), which can cause an abrupt, febrile, and flu-like illness often associated with
