Fig. 4
The condensed phylogenetic relationships of Protostrongylids based on ITS-2 sequences of the rDNA, using the Neighbor-Joining method with the Tamura 3-parameter method. The percentages of replicate trees in the bootstrap test (1000 replicates) are shown next to the branches. The analysis involved 14 rDNA ITS-2 nucleotide sequences (5 from antelopes, 4 from local sheep and 5 from Genbank). Evolutionary analyses were conducted in MEGA7.

The phylogenetic relationships showing topology of Protostrongylids using the Neighbor-Joining method with the Tamura 3-parameter method with the bootstrap test (1000 replicates) shown next to the branches. The analysis involved 10 rDNA ITS-2 nucleotide sequences (2 from antelopes and 8 from Genbank). Evolutionary analyses were conducted in MEGA7.
