Global Status of Porcine circovirus Type 2 and Its Associated Diseases in Sub-Saharan Africa

Figure 2

Four main genotypes of PCV2 as shown by phylogenetic tree that was constructed based on neighbor-joining method for complete genomes of some PCV2 sequences obtained from NCBI Genbank; genotypes of the virus were written on the main branches of the tree and PCV1 was used as outgroup (NB: the tree was constructed using Geneious 9.1.5, Biomatters Ltd. Boostrap values obtained from 1000 replicates are shown at the major nodes).
