In Situ Localization of Staphylococcus shinii and Staphylococcus succinus in Infected Rhipicephalus microplus Ticks: Implications for Biocontrol Strategies

Pathogens
Rhipicephalus microplus is a blood-sucking parasite that causes heavy infestations on cattle and is a vector for severe tick-borne diseases, such as anaplasmosis and babesiosis, and poses a significant threat to the cattle industry.

Ticks and tick‐borne bacterial pathogens found on hard ticks (Acari: Ixodidae) on cattle in the Central River region of The Gambia

Medical and Veterinary Entomology, Volume 40, Issue 1, Page 91-100, March 2026.
First detection of Ehrlichia minasensis, Anaplasma marginale and hemotropic Mycoplasma spp. in cattle in The Gambia. Identification of four tick species, with Hyalomma marginatum being the most common. 15.6% of ticks tested positive for tick‐borne pathogens, including Ehrlichia spp., A. marginale and hemotropic Mycoplasma spp.

Amblyomma cajennense Sensu Stricto (Fabricius, 1787) and Amblyomma sculptum (Berlese, 1888) Tick Saliva Elicit Immune‐Modulatory Activity in Isolated Murine Macrophages With an Insight Into Proteomic Analysis

Parasite Immunology, Volume 48, Issue 3, March 2026.
ABSTRACT Tick saliva is known to cause immunosuppression and help pathogen transmission. Amblyomma sculptum is a public health concern as a vector of Rickettsia rickettsii. Another close‐related species is Amblyomma cajennense sensu stricto (s.s.). The impact of saliva from these species on murine macrophages remains unclear.

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 ...
