Recipe ingredients for re emergent protozoa: climatic change, rain, zoonosis, mountain and food
Abstract
When someone says that global concentrations of carbon dioxide (CO2) have continued to increase in the atmosphere to reach annual averages of 410 parts per million, it does not mean much to most people1. But certainly, the consequen-ces of the changes derived from alterations on the hydro-logical and meteorological cycles have an impact on many living systems, including zoonosis2. Global climate change produces ecological perturbations, which cause phenologi-cal shifts, as well as alterations in parasite transmission, with the potential for host switching3–5. The intersection of climate change with transmission dynamics, called ecological fitting, permits emergence of parasites and diseases without evolu-tionary changes in their capacity for host utilization6–8.
