Clinical evaluation for each piglet post infection. After infection, mean rectal temperatures (a), mean clinical score (b) and body weight (c) of each animal were measured daily in HP-PRRSV inoculation group (PRRSV, n = 5) and control group (Control, n = 5). Rectal temperatures equal or above 41 °C (≥41 °C) were defined as fever. Data are presented as mean values ± SD. Asterisks indicate significant differences (**p < 0.01) between infected and control groups
