Clinical Characteristics and Diagnostic Prediction of Severe Fever with Thrombocytopenia Syndrome and Rickettsiosis in the Co-Endemic Wakayama Prefecture, Japan

Medicina, 2023
Background and Objectives: The Wakayama prefecture is endemic for two types of tick-borne rickettsioses: Japanese spotted fever (JFS) and scrub typhus (ST). Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne hemorrhagic viral disease with

Potential Role of Avian Populations in the Epidemiology of Rickettsia spp. and Babesia spp.

Veterinary Sciences, 2021
Birds often are carriers of hard and/or soft ticks harboring pathogens of humans and veterinary concern. Migratory avian species, which cover long distance by their flight, may deeply influence the ticks’ distribution worldwide; in particular, they can ...

Detection of causative agents of tick-borne rickettsioses in Western Siberia, Russia: identification of Rickettsia raoultii and Rickettsia sibirica DNA in clinical samples. [PDF]

Clinical Microbiology and Infection, 2017
The main causative agent of tick-borne rickettsioses in Siberia is considered to be Rickettsia sibirica; however, only a few cases have been genetically confirmed. Other pathogenic species of Rickettsia have been detected in ixodid ticks in Western Siberia.

Molecular detection of Rickettsia spp. in wild ungulates and their ticks in Mediterranean areas of southwestern Spain

Zoonoses and Public Health, Volume 70, Issue 6, Page 485-497, September 2023., 2023
Abstract Wildlife is an important reservoir of zoonotic pathogens. The objective of the present study was to assess the importance of wild ungulates in the epidemiology of Rickettsia spp. Ticks and spleen samples were collected from 262 red deer (Cervus elaphus) and 83 wild boar (Sus scrofa) hunted in southwestern Spain over a 5‐year period.

Distribution and molecular characterization of rickettsiae in ticks in Harbin area of Northeastern China.

PLoS Neglected Tropical Diseases, 2020
Tick-borne rickettsioses are world-spreading infectious zoonoses. Ticks serve as reservoirs and vectors for Rickettsia and play a key role in transmission of rickettsioses.

Estimating the distribution of Oryzomys palustris, a potential key host in expanding rickettsial tick‐borne disease risk

Ecosphere, Volume 14, Issue 3, March 2023., 2023
Abstract Increasingly, geographic approaches to assessing the risk of tick‐borne diseases are being used to inform public health decision‐making and surveillance efforts. The distributions of key tick species of medical importance are often modeled as a function of environmental factors, using niche modeling approaches to capture habitat suitability ...

New geographical records for tick‐borne pathogens in ticks collected from cattle in Benin and Togo

Veterinary Medicine and Science, Volume 9, Issue 1, Page 345-352, January 2023., 2023
A total of 396 ticks were collected from cattle between 2019 and 2020, and divided in pools (two to six ticks per pool) for molecular screening. The present study highlights the presence of zoonotic agents in ticks collected from cattle in Benin and Togo.

Surgical Removal of a Tick-Bite Region Without the Presence of an Insect Body. [PDF]

Clin Case Rep
Surgical excision of a tick‐bite lesion revealed retained mouthparts despite the absence of a visible tick body. Dermoscopy demonstrated chelicerae imprints, and histopathology confirmed the presence of residual tick structures. This case highlights the combined diagnostic value of dermoscopy and histopathology in cases where the tick body is not found.

Evaluating the Clinical and Immune Responses to Spotted Fever Rickettsioses in the Guinea Pig‐Tick‐Rickettsia System

Current Protocols, Volume 2, Issue 11, November 2022., 2022
Abstract The guinea pig was the original animal model developed for investigating spotted fever rickettsiosis (SFR). This model system has persisted on account of the guinea pig's conduciveness to tick transmission of SFR agents and ability to recapitulate SFR in humans through clinical signs that include fever, unthriftiness, and in some cases the ...
