Fig. 7From: A descriptive study on spatial and temporal distributions of genetic clusters of porcine reproductive and respiratory syndrome virus infecting pig sites in Quebec, Canada, between 2010 and 2019Distribution of genetic distances among wild-type sequences in three administrative regions according to year. A total of 2222 wild-type sequences (1 randomly selected per pig site and per year,) submitted between 2010 and 2019 were included. Within a specific year, regions with different letters indicate a significant pairwise difference in genetic diversity from the molecular analysis of variance (AMOVA) (P < 0.002), considering a Bonferroni adjustment for multiple testing.
