Silencing expression of the Rhipicephalus microplus vitellogenin receptor gene blocks Babesia bovis transmission and interferes with oocyte maturation
... A splenectomized Holstein calf (C90979) 3–4 months of age, that tested negative for B. bovis by PCR [17] and cELISA [19], was used in this study. The animal was main- tained according to protocols approved by the ...

Rhipicephalus (Boophilus) microplus aquaporin as an effective vaccine antigen to protect against cattle tick infestations
... Several of these gene coding regions were discovered to encode proteins with significant amino acid similarity to aquaporins. Aquaporins, originally called water channels, allow the regulation of water transport across ...

Immune related redox metabolism of embryonic cells of the tick Rhipicephalus microplus (BME26) in response to infection with Anaplasma marginale
... Herein, we show that different microbial stimuli trigger distinct gene expression profile of components of the pro- oxidant/antioxidant system in BME26 cells. Remarkably, A. marginale exposure triggers the downregulation ...
