Leukocyte count and antibody detection in the sera from HP-PRRSV infected and control piglets. The heparinized blood sample from each piglet was collected for white blood cell counts (a); ELISA anti-PRRSV antibody titers in the sera were determined with the IDEXX PRRS ELISA kit (b). Values represent average titers from five animals. Dashed line at 0.4 S/P ratio designates threshold value above which titers are considered positive for anti-PRRSV antibodies. Data from groups of n = 5 piglets are expressed as means ± SD. The horizontal lines represent the geometric mean for each group and statistical analysis was performed and the data are shown as * p < 0.05, ** p < 0.01, *** p < 0.001
