Figure 1From: Reduction of porcine circovirus type 2 (PCV2) viremia by a reformulated inactivated chimeric PCV1-2 vaccine-induced humoral and cellular immunity after experimental PCV2 challengeMean values of the genomic copy number of porcine circovirus type 2 DNA in serum and nasal swabs from vaccinated challenged (T01; □ for serum and ■ for nasal swab) and non-vaccinated challenged (T03; ◯ for serum and ● for nasal swab) animals. Variation is expressed as the standard deviation. Significant difference is indicated at p value <0.001*.Back to article page
