| Abstrakt: | Background: HEV is endemic in several Middle Eastern countries including Saudi Arabia, which hosts the annual pilgrimage for Muslims from around the world. One of the Hajj rituals is the sacrifice of animals, including camels, cows, goats, and sheep. HEV Zoonosis is established in swine and other suspected species, including deer, rabbits, dromedary, and Bactrian camels. HEV was identified in small, domesticized animals like goats, cows, sheep, and horses. We previously investigated HEV seroprevalence in Camels. This study aimed to evaluate HEV seroprevalence in other highly consumed ruminants in Saudi Arabia, namely cows, sheep, and goats. Methods: Sera from cows (n = 47), goats (n = 56), and sheep (n = 67) were analyzed for the presence of HEV-IgG by using in-house developed ELISA assays. Results: The highest seroprevalence was found in sheep (62.7%), followed by cows (38.3%), and then goats (14.3%), with a p-value of < 0.001. No other demographic characteristics of the animals were significantly correlated with the HEV seroprevalence. Conclusions: This study provides baseline data as the first study on the seroprevalence of HEV in ruminant animals in Saudi Arabia. The high seroprevalence found in sheep and cows must be further investigated for the potential zoonotic HEV transmission to humans. Further studies are needed to investigate the active viremia in these animal species through nucleic acid detection and sequencing to provide data on the circulating HEV genotypes among the targeted animal species. The detection of HEV in different animal products, such as milk, liver, and others, also remains an important study area to consider. |
