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 0.4Ā S/P ratio designates threshold value above which titers are considered positive for anti-PRRSV antibodies. Data from groups of nā€‰=ā€‰5 piglets are expressed as meansā€‰Ā±ā€‰SD. The horizontal lines represent the geometric mean for each group and statistical analysis was performed and the data are shown as * pā€‰<ā€‰0.05, ** pā€‰<ā€‰0.01, *** pā€‰<ā€‰0.001
