Figure 2From: Increased Toxoplasma gondii positivity relative to age in 125 Scottish sheep flocks; evidence of frequent acquired infectionT. gondii seroprevalence in sheep according to age of animal. The percentage of sheep being T. gondii seropositive increased from 37.3%, in animals that are one year old, to 73.8% in animals that are more than 6 years old, while the number of borderline samples stayed fairly unchanged for the different age groups. Borderline cases were excluded from the calculation of the age-related T. gondii seroprevalence.Back to article page
