From: Bottlenecks in the transmission of porcine reproductive and respiratory syndrome virus (PRRSV1) to naïve pigs and the quasi-species variation of the virus during infection in vaccinated pigs

Figure 1

Summary of the 14 transmission events studied. A Intranasal inoculation of 9 naïve pigs using a nebulizer; B Experimental infection in a 1:1 basis of 5 non-vaccinated naïve pigs (R1 to R5) from seeders (D1 to D5). Nucleotide diversity (π) estimations of the donor population (orange boxes) and the founder variants, in green boxes if the global diversity decreased and in red if an increase was reported. The donor animals, the recipient animals, and the nucleotide diversity estimations are also depicted in Table 1.
