Course of NDV challenged chickens. Six-weeks-old naive SPF-chickens (A) or SPF-chickens infected/vaccinated with APMV-8 at the age of 3 weeks (B) were challenged with virulent NDV Herts 33/56 and monitored for clinical signs. Numbers indicate clinical index. Virus shedding was tested by NDV-specific RT-qPCR 2 days pch (C) for SPF-chickens (I) and APMV-8 vaccinated chickens (II). Given are genome equivalents (GEQ) derived from a standard curve prepared for each PCR-run. Differences between groups were statistically tested by appropriate Wilcoxon-tests for paired data. The global significance level was 0.05. All calculations were performed using R software[23], version 2.13.0(2011-04-13).
