Phylogenetic relationship of Echinococcus granulosus -complex genotypes recovered from Sudanese camels and other genotypes identified globally. Partial NADH dehydrogenase subunit 1 gene sequences generated from EG isolates were aligned with sequences of other EG isolates from different parts of the world. Sequences were analyzed with the BioEdit software (Ibis Biosciences, Carlsbad, CA, USA). The phylogenetic tree was constructed using Unweighted Pair Group Method with Arithmetic mean (UPGMA) implemented in MEGA software version 5 [36]. Bootstrap values were calculated from analysis of 1000 replicates of the data set, and values greater than 50% are indicated at the appropriate nodes. Each EG isolate is designated by the country of origin, GenBank accession number and the genotype of the isolate when available. The GenBank accession numbers (JN637176, JN637177) were given for the Sudan isolates of genotype 5 (E. ortleppi) and genotype 6 (E. canadensis), respectively. Corresponding nucleotide sequence of NADH 1 of Taenia multiceps, GenBank accession number HM143887.1, is used as an out group in the constructed phylogenetic tree. The strains from Sudan are highlighted in red color for clarity.
