FMO5 and Increased total eosinophil count: Despite enhanced eosinophilia in CD200R−/− mice, fungal burden was not significantly altered, which is in contrast to other studies where a reduction in eosinophilia (for example in surfactant protein D, Scavenger Receptor A, NADPH oxidase or eosinophil knockout mice) 25, 26 is associated with reduced fungal burden.
