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 ...

Development and Characterization of Microsatellite Genetic Markers for Hyalomma rufipes, a Tick Vector of Crimean‐Congo Hemorrhagic Fever Virus

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study developed and validated 14 polymorphic microsatellite markers to investigate the population genetics of Hyalomma rufipes, a tick species that transmits Crimean‐Congo Hemorrhagic Fever Virus (CCHFV) in East Africa. Ticks collected from livestock in northern Kenya were morphologically and genetically identified, followed by genome sequencing ...

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.

Evaluation in vitro of the infection times of engorged females of Rhipicephalus (Boophilus) microplus by the entomopathogenic nematode Steinernema glaseri CCA strain Avaliação in vitro dos tempos de infecção de fêmeas ingurgitadas de Rhipicephalus (Boophilus) microplus pelo nematoide entomopatogênico Steinernema glaseri estirpe CCA

Ciência Rural, 2010
Studies have shown that ticks are susceptible to infection by entomopathogenic nematodes. These studies indicate different susceptibilities of ticks to infection by these fungi, depending on the tick species, development phase, entomopathogenic nematodes
