The Long-Jumping of African Swine Fever: First Genotype II Notified in Sardinia, Italy

Figures

  Figure 1. A maximum likelihood phylogenetic tree inferred from the dataset composed of p72 (A) and p54 (B) sequences by the GTR+G+I model of nucleotide substitution. Strains under study are indicated with green circles. Bootstrap values < 70 are not shown. The scale bar indicates the number of substitutions per site.

  Figure 3. Location of the outbreak farm (blue star) and the pig farms (black dots) located in the protection and surveillance area (pink) around the outbreak with respect to restriction zones I (light blue), II (light pink), and III (red) for ASFV genotype I in Sardinia.

  Figure 4. The figure illustrates the tracing of the meat and meat products that hypothetically caused the ASFV genotype II outbreak. On the left, the flow chart indicates each actor involved; on the right, the time and actions are described.

  Figure 5. This figure geographically illustrates the tracing (arrows) of the meat and meat products that hypothetically caused the ASFV genotype II outbreak. Actors A (red dot), B (yellow triangle), C1 (blue pentagon), C2 (green pentagon), C3 (blue pentagon), and D2 (red dot) refer to farms in Zinasco (Pavia province, Lombardia region), wholesalers in Cesena (Forlì-Cesena province, Emilia-Romagna region), retailers in Northwest Sardinia, retailers in Northeast Sardinia, retailers in South Sardinia, and a farmer in Dorgali, respectively. The blue areas indicate level I restriction zones, the pink areas indicate level II restriction zones, the red area indicates the level III restriction zone, and the violet areas indicate the protection and surveillance areas around outbreaks.
