Abstract
Hydatid cyst disease, caused by Echinococcus granulosus sensu lato (s.l.),
is linked to endemic areas in the Levant region, such as Jordan. There is a
scarcity of epidemiological data about this disease. Our goal was to pinpoint
the particular genotypes accountable for sheep and goat infection in unexplored
regions of Southern Jordan. Partial sequences of cytochrome C oxidase (Cox1,
450 bp) and NADH dehydrogenase subunit 2 (Nad2, 820 bp) of the E.
granulosus from Jordan were analysed and compared with E. granulosuss.l. reference genomes, to infer the phylogeny of the species. This
analysis demonstrated a significant degree of intraspecific similarity and
identified the presence of E. granulosus sensu stricto (G1, G3). The G1
genotype was the most prevalent (Cox1, n = 17/17); (Nad2, n =
13/18). The study examined partial Cox1 sequences from different
countries (Jordan, Lebanon, Iran, India) and regions (South America) to analyze
the genetic architecture and phylogeography of the G1 genotype at regional and
global levels. One primary haplotype (Hap_1) was present in the research
locations. We hypothesized that a certain branch of G1, known as Hap_1, was
prevalent among regions that were not geographically connected. Future research
on the biology and distribution of E. granulosus s.s. will be enhanced by
this information.
