Candidatus Rickettsia xinyangensis as Cause of Spotted Fever Group Rickettsiosis, Xinyang, China, 2015

Emerging Infectious Diseases, 2020
In 2015, we evaluated 221 patients with undifferentiated fever and tick bite or animal exposure in Xinyang, China, for Rickettsia infection. Three with mild disease were infected with Candidatus R. xinyangensis, which clustered with R.

Langat Virus Biology and Infection

Reviews in Medical Virology, Volume 36, Issue 2, March 2026.
ABSTRACT Flaviviruses pose a major threat to global health and can cause severe disease in animals and humans. Among them, tick‐borne encephalitis virus (TBEV) and related members of the tick‐borne encephalitis (TBE) serocomplex are transmitted primarily by ticks and can lead to neurological disease, including encephalitis and death. Despite many years

A humanized NOG‐EXL mouse model for producing severe fever with thrombocytopenia syndrome virus–reactive human antibodies

Animal Models and Experimental Medicine, Volume 9, Issue 2, Page 378-388, February 2026.
Humanized mouse models are essential for studying human immune response and antibody development. However, conventional models exhibit limited B cell maturation and antigen‐specific humoral responses. To overcome these limitations, we used the NOG‐EXL mice expressing human interleukin 3 (IL‐3) and granulocyte‐macrophage colony‐stimulating factor (GM ...

Spotted fever group rickettsiae (SFGR) detection in ticks following reported human case of Japanese spotted fever in Niigata Prefecture, Japan

Scientific Reports, 2021
Japanese spotted fever, a tick-borne disease caused by Rickettsia japonica, was firstly described in southwestern Japan. There was a suspicion of Rickettsia japonica infected ticks reaching the non-endemic Niigata Prefecture after a confirmed case of ...

Seasonality, Moisture, and Host Community Structure of Haemaphysalis Ticks in a Subtropical Urban Mosaic in Hong Kong, China

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We integrated field surveys, DNA barcoding and integrative taxonomy, iDNA, and ecological modeling to resolve the distributions, seasonality, and host use of Haemaphysalis ticks across Hong Kong. Moisture was indicative of adult activity, and iDNA suggested predominant feeding on wild mammals, particularly wild boar and porcupine.

Investigation of tick-borne bacterial microorganisms in Haemaphysalis ticks from Hebei, Shandong, and Qinghai provinces, China

Ticks and Tick-Borne Diseases
Tick-borne microorganisms in many tick species and many areas of China are still not thoroughly investigated. In this study, 224 ticks including two species (Haemaphysalis longicornis and Haemaphysalis qinghaiensis) were collected from four cities in ...

Borrelia miyamotoi sensu lato in Père David Deer and Haemaphysalis longicornis Ticks

Emerging Infectious Diseases, 2018
By sequence analysis of 16S rRNA, flaB, p66, and glpQ, we identified Borrelia miyamotoi in 1 of 4 Père David deer (n = 43) seropositive for Borrelia spp. and 1.2% (3/244) of Haemaphysalis longicornis ticks from Dafeng Elk National Natural Reserve, China.

RNAi Regulator C3PO Promotes Arbovirus Infection in Insect Vectors

Advanced Science, Volume 13, Issue 4, 19 January 2026.
RNA interference (RNAi) is vital for eukaryotes to defend against virus infection. The C3PO complex takes part in RNAi but its role in regulating viral infection remains unclear. This work finds that insect C3PO facilitates arbovirus replication by degrading precursors of miRNAs, especially miR‐971‐3p.
