Description
Ricardo Lopes and seven colleagues report a 2026 nationwide survey of dog exposure to two tick-borne infections in Portugal, Ehrlichia canis and Babesia species. Dogs act as sentinels whose blood shows where ticks are passing germs that also matter for wider One Health surveillance.
Nearly three thousand serum samples collected between 2015 and 2025 were tested for antibodies. Exposure was higher for Babesia, at twelve percent, than for Ehrlichia, at four percent. Ehrlichia clustered in the warm south, notably the Algarve, and rose in older dogs. Dogs positive for Babesia were also likelier to carry Ehrlichia antibodies, suggesting shared tick exposure.
