Figure 1: Histologic section with a gravid, femaleOnchocerca lupi specimen embedded in the episclera of a dog from
South Texas. The cuticular pattern of two inner striae (dashed arrows)
within the space between two outer cuticular ridges (solid arrows) aided
in the species—level identification. (H&E, 40X, Bar = 50µm).
Figure 2: Phylogenetic relationship of based on cox1gene of Onchocerca lupi nematode isolate from a dog in South
Texas, United States (GenBank accession no. MW577256), and otherOnchocerca spp. isolates. Analysis was performed using the
Maximum Likelihood method (1,000 bootstrap replicates). Nodes with less
than 90% support were condensed.
