Predictive models and experimental manipulations aiming to investigate relationships between climate change and infectious disease have primarily focused on host exposure, risk of infection and disease spread. However, host immunity to infection is an important source of variation among individuals and the way this affects the impact of climate change on host-pathogen interactions needs to be considered.
On Friday, March 17, Dr. Isabella Cattadori will discuss the use of a combination of long-term field observations, field and laboratory manipulations and mathematical modelling of a rabbit-helminth system, to explore whether heterogeneities in the host immune response exacerbate or suppress the impact of climate warming on the dynamics and persistence of two gastrointestinal helminths.
Dr. Cattadori is an Associate Professor of Biology, Department of Biology and The Huck Institute, CIDD - Center for Infectious Disease Dynamics, at Pennsylvania State University. She works on different aspects of the ecology of infectious diseases driven by fundamental questions of human, livestock and wildlife concern. Dr. Cattadori is interested in the processes and factors that generate host heterogeneity to infection and transmission, both at the individual and the host population level. Her work is focused primarily on gastrointestinal helminths but also includes bacteria and viruses.
