The replication of low pathogenic H4N6 AIV in chicken macrophages (MQ-NCSU cell line).

<p>Chicken macrophages were infected with low pathogenic H4N6 AIV at a MOI of 1. Cell supernatants were collected at 0, 6, 16, 24, 31 and 42 hours post-infection. This figure is representative of three separate experiments with four biological replicates per time point. Virus titre is represented by the log₁₀ TCID₅₀. Significant differences (<i>P</i> ≤ 0.05) between the viral titer at a specific time point and the time of infection (time 0) are indicated by an *.
