Summary

This research article examines the presence of medical and veterinary pathogens in Haemaphysalis longicornis ticks across Ohio and Pennsylvania. By testing over 500 specimens, scientists confirmed the presence of Anaplasma phagocytophilum, Babesia odocoilei, and Theileria orientalis Ikeda within these invasive populations. The study highlights the first known detection of certain pathogens in host-seeking ticks in these specific regions, marking a shift in local epidemiological risks. While the ticks were found to be incompetent vectors for some diseases, their rapid reproduction and broad habitat range pose a growing threat to livestock and public health. The authors conclude that ongoing active surveillance is essential for developing effective prevention and control strategies as the species expands its footprint in North America.
