Fig. 1From: Pathological and immunological characteristics of piglets infected experimentally with a HP-PRRSV TJ strainClinical 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, nā=ā5) and control group (Control, nā=ā5). Rectal temperatures equal or above 41Ā Ā°C (ā„41Ā Ā°C) were defined as fever. Data are presented as mean valuesāĀ±āSD. Asterisks indicate significant differences (**pā<ā0.01) between infected and control groupsBack to article page
