Spatial Distribution and Host‐Specific Patterns of Avian Haemosporidian Infections in a Semi‐Arid Region of Northeastern Iran

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
A survey of 263 birds across 10 species in Semnan Province, Iran, revealed a 22.1% prevalence of avian haemosporidian infections, dominated by Haemoproteus spp. Pigeons showed significantly higher infection risk. Spatial analysis identified clustering in Shahroud County, suggesting local climatic and ecological conditions influence parasite ...

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Itch‐induced tick removal (IITR): An acquired neuroimmune mechanism, itch‐induced tick removal, develops after repeated tick exposure, mobilizing T cells and macrophages at the tick bite site to trigger a rapid scratching response that facilitates timely tick removal within a critical window that precedes the transmission of many tick‐borne pathogens ...
