Phylogenetic comparison of West Nile virus (WNV) nonstructural protein 5 partial gene fragment identified in a veterinary student’s serum and in the virus isolate obtained from mouse brain and the horse’s brain after autopsy (triangles) relative to other WNV strains from South Africa and elsewhere. The neighbor-joining tree was compiled by using MEGA version 4 software (www.megasoftware.net/under) and 1,000 bootstrap replicates by using the maximum composite likelihood algorithm.

Figure. Phylogenetic comparison of West Nile virus (WNV) nonstructural protein 5 partial gene fragment identified in a veterinary student’s serum and in the virus isolate obtained from mouse brain and the horse’s brain after autopsy (triangles) relative to other WNV strains from South Africa and elsewhere. The neighbor-joining tree was compiled by using MEGA version 4 software (www.megasoftware.net/under) and 1,000 bootstrap replicates by using the maximum composite likelihood algorithm. Genetic lineages are indicated on the right as described (3–7). Scale bar indicates nucleotide substitutions per site. JEV, Japanese encephalitis virus (included as outgroup).
