“…For instance, a study by Merst et al (2023) explored the infection rates among stray dogs and slaughtered animals in the Al-Kharj region in Saudi Arabia, revealing a 14% infection rate in dogs and rates of 9.18%, 7.5%, and 10% for sheep, goats, and camels, respectively. Another study in the eastern region of Saudi Arabia identified three Echinococcus species in camels E. granulosus, E. Canadensis, and E. ortleppi (Al-Hizab et al, 2021). The prevalence of Echinococcosis, a zoonotic disease, is notable among livestock in the Arabian Peninsula countries (Al-Shaibani et al, 2021) and is a global concern (Alvi and Alsayeqh., 2022).…”

Echinococcosis, or hydatidosis, is a serious veterinary disease and public health issue worldwide, particularly in rural areas in which dogs have frequent contact with local herbivores. This study assessed the frequency of hydatidosis found among farm animals slaughtered in Al-Jouf Province in northern Saudi Arabia in 2021. A total of 156754 sheep, 36337 goats, 8590 camels, and 986 cattle were inspected for hydatidosis infection by comprehensive evaluation involving meticulous visual inspection and manual exploration of the internal organs through palpation. The cysts were subjected to molecular and phylogenetic analysis. The overall prevalence rates of hydatid cysts were 0.43%, 0.19%, 0.54%, and 0.51% in the inspected sheep, goats, camels, and cattle, respectively. The highest disease prevalence rates among sheep (27.8%) and goats (30.9%) occurred in the spring, and the highest prevalence rates among camels (41.3%) and cattle (80%) were in the summer. Regarding the prevalence of the disease in four slaughterhouses in the Al-Jouf Province, the highest prevalence in sheep, goats, and camels was in the Tabarjal slaughterhouse (1.43%, 0.81%, and 1.08%, respectively), although the Al-Qurayat slaughterhouse had the highest prevalence rate in cattle (1.98%). Complete molecular analysis indicated that cytochrome c oxidase subunit 1 (cox1) sequences from cyst isolates belonged to Echinococcus granulosus (E. granulosus). Moreover, there was high homology (98-100%) with associated Genbank sequences of E. granulosus isolated from sheep in the Kingdom of Saudi Arabia (KSA). Sheep and camels were a significant source of hydatidosis transmission to dogs and helped to maintain disease incidence in the Al-Jouf Province. Thus, significant efforts should focus on preventing cyst transmission from abattoirs and infected stray dogs.

Taeniids, consisting of two genera Echinococcus and Taenia, are obligatory tapeworms of mammals, and their pathogenicity was due to infection with larval stages. Hydatid (the larval stage of Echinococcus granulosus) and coenurus (the larval stage of Taenia multiceps) cysts are prevalent in domestic, wild ruminants, livestock, swine, and dogs, and accidentally they could also be found in humans. They lead to different clinical manifestations that cause economic loss in livestock and human morbidity. In Saudi Arabia, few studies were performed on hydatid and coenurus cyst genetic variations. The main goal of the present study was to identify E. granulosus and T. multiceps cyst isolates collected from slaughtered Harri sheep in Saudi Arabia by partial sequencing with PCR amplification of the cytochrome C oxidase 1 (COX1) gene. Molecular and phylogenetic evaluation based on COX1 sequences indicated that cyst isolates belong to E. granulosus and T. multiceps, respectively, successfully submitted in NCBI Genbank. Molecular characterization showed a low nucleotide diversity with two submitted isolates of coenurus with related isolates of Genbank. Conversely, E. granulosus isolates showed higher nucleotide diversity. The reported data could serve as a foundation for future molecular epidemiological and biological studies.
