Silencing expression of the Rhipicephalus microplus vitellogenin receptor gene blocks Babesia bovis transmission and interferes with oocyte maturation

Parasites & Vectors, 2019
Background Rhipicephalus microplus is an efficient biological vector of Babesia bovis, a causative agent of bovine babesiosis. Babesia bovis is passed transovarially to the next generation of ticks, which then transmit the parasite to naïve animals.

Biochemical Characterization of a Kunitz‐Type Protease Inhibitor From Mimosa regnellii and Its Effects on Melanoma Cell Viability and Angiogenesis

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
A Kunitz‐type serine protease inhibitor (JTI) purified from Mimosa regnellii seeds selectively targets melanoma cells. JTI triggers mitochondrial apoptosis, increases ROS and Ca2+ levels, arrests the cell cycle, and suppresses migration and angiogenesis without affecting healthy cells.

Early Tick Species Identification Using Eschar‐Based PCR to Guide Presymptomatic Risk Assessment in Tick‐Borne Diseases

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT In endemic regions where simultaneous larval tick bites frequently occur, early identification of tick species from eschar lesions may substantially influence presymptomatic clinical triage. We report a 78‐year‐old woman who was found after approximately 24 h of wandering, presenting with multiple clustered eschars on the lower extremities and
