| Hydatidosis is a potential zoonotic helminthic disease affect ing a broad spectrum of
mammals, including humans, worldwide. The current review was conducted to investigate
the genotypic status and prevalence of hydatid disease in camels across the world. For the
purpose of the study, the articles addressing the worldwide prevalence of hydatidosis in
camels were searched in several English language databases. The search process resulted in
the inclusion of 122 papers. Based on the data presented in the reviewed articles, the pooled
prevalence of hydatid disease in camels across the world was measured at 23.75% (95%
CI=20.15-27.55). Moreover, the subgroup analysis demonstrated significant differences in
the overall prevalence of hydatidosis among camels based on year, geographic area, gender,
infected organ, fertility rate of the cyst, and diagnostic technique (P<0.001). Furthermore, the
E. granulosus genotypes identified in camels with hydatidosis included G1, G2, G3, G1-G3,
G5, G6, G7, G6-G7, and G6-G10, with G6 being the most common genotype throughout the
world. The data obtained from the current study are central to the better conceptualization of
the biological and epidemiological characteristics of E. granulosus s.l. genotypes around the
world, which can be helpful in the planning and adoption of more comprehensive control
strategies. |
