ODDS ratio a for detected virus and PMWS; Wald Chi2 test to evaluate the statistical significance of b specific lesions observed in lungs; c amount and level of replication PCV2 in PPV2 positive and PPV2 negative animals. d statistical significance in difference of presence of T lymphocytes, B lymphocytes and macrophages in alveolar walls; in alveolar spaces; in peribronchial area and in perivascular area in PPV2 positive and PPV2 negative. Positive Wald Chi2 values means that observed lesion was more frequently observed in PPV2 positive animals while negative Wald CHi2 value means that observed lesion was less frequently observed in PPV2 negative animals
