(A) Viral RNA copy numbers in the tissues of domestic pigeons in response to PPMV-1 strain LHLJ/110822 infection. Viral RNA copy numbers in the tissues from domestic pigeons in each group were measured by real time RT-PCR at 1, 3, and 7 dpi. The results represent the mean of 3 independent experiments with 3 replicates per experiment. The results are expressed as means ± standard errors (SEM). Statistical analysis was performed using IBM SPSS 19.0 statistical software (IPSS, Inc., Chicago, IL). a,bThe values with different letters are significantly different (P < 0.05). (B) Serum samples were collected to measure serum antibody levels of pigeons inoculated with the PPMV-1 strain LHLJ/110822. Antibodies were examined by HI every 4 d from the eighth day to 28th day. Values are presented as mean ± SEM (statistical significance: ∗P < 0.05). The data were analyzed by using IBM SPSS 19.0 statistical software (IPSS, Inc., Chicago, IL). Abbreviations: HI, hemagglutination inhibition; PPMV-1, pigeon paramyxovirus type 1.
