The proliferation rate of human brain microvascular endothelial cells [HBMECs] infected and non-infected with Neospora caninum as a function of time in hours [x axis]. The proliferation of HBMECs with and without infection was assessed by the MTT assay. Group: Red = control HBMECs; blue = infected HBMECs. Data points are the mean of quadruplet readings. The intercept of the model was the absorbance at t = 1 hr in the control group. The model coefficients represent the difference to this reference. After having accounted for time, there was no significant difference between the control and infected group. Experiment was repeated at least 3 times.
