Figure 1. Homologous serum antibody responses in chickens inoculated with APMV serotypes 1-9.

Figure 1

Chickens in groups of 8 were inoculated via the oculo-nasal route with prototype strains of APMV serotypes 1-9, using the lentogenic LaSota strain in the case of APMV-1. A negative control group was mock-inoculated. Sero-conversion to the infecting APMV serotype was evaluated by HI assay except in the case of APMV-5 (*), which was evaluated by 50% plaque reduction assay. Antibody titers are expressed as mean reciprocal log2 titer with SEM (standard error of the mean) indicated, and titers above the dotted line were considered positive. Statistical differences were calculated by one-way ANOVA based on non-parametric test with a P value < 0.0001.
