Schematic diagram showing the summary results of predictors for infectious disease mortality (ID-mortality), with the size of effect. The estimated ID-mortality was 13.3 (10.4-16.3; 95% CI) per 100 calf years at risk. The variables with a -ve sign on the lines have a protective effect against ID-mortality. The main pathogens identified to be associated with increased risk for death are infection with Trypanosoma spp. mainly being T.vivax, high intensity infection with Theileria spp. as observed at microscopy, and high worm burden measured by the strongyle eggs per gram of faeces. Seroconversion to T.parva was associated with a protective effect.
