Rodents were found to harbour six assemblages (A\u2013E, G) and four sub\u2010assemblages (AI, AII, BIII, BIV) of\n                      <jats:italic>G. duodenalis<\/jats:italic>\n                      , with marked geographic variation. The highest pooled prevalence was observed in Europe (17.9%; 95% CI: 9.8\u201330.5), where assemblages C, D, G, and most occurrences of E, B, and A were reported. Assemblages C and D were entirely absent in Asia. In contrast, most reports of the rodent\u2010specific assemblage G originated from Asia. South America (represented solely by Brazil) reported only assemblage A.

Belgium also showed notable diversity (A, B, C, E), with assemblage B being the most prevalent in both countries. Assemblage D was found exclusively in Romania, while assemblage C was reported only in Belgium and Italy. Notably, the highest assemblage diversity was observed in chinchillas (five: A\u2013E), squirrels (four: A, B, E, G), and rats (three: A, B, G).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      Although various rodent species, especially chinchillas, mice, porcupines, rats, squirrels, and voles, carry\n                      <jats:italic>G. duodenalis<\/jats:italic>\n                      zoonotic assemblages (A and B), the overall molecular prevalence in rodents remains relatively low.
