Figure 3From: The index herd with PMWS in Sweden: Presence of serum amyloid A, circovirus 2 viral load and antibody levels in healthy and PMWS-affected pigsMean log levels of PCV2 DNA copy number in serum. Black circles represent pigs diagnosed with PMWS (n = 4). All these pigs were dead at day 55. Pigs without clinical signs of PMWS were grouped as having low (squares, n = 17) or high (triangles, n = 17) maternal immunity to PCV2. All these pigs were alive at day 55. ** illustrates that the indicated groups differ (p < 0.01) from the group with high maternal immunity to PCV2 at that day.Back to article page
