In this study, 412 fresh horse fecal samples were collected from four Chinese regions covering four rearing systems and were screened for\n                    <jats:italic>E. bieneusi<\/jats:italic>\n                    internal transcribed spacer (ITS) sequences via nested PCR, with risk factor and phylogenetic analyses conducted. The overall infection prevalence reached 15.0% (62\/412), varying geographically from 9.7% (Wenzhou) to 29.3% (Qiqihar). Foals &lt;1 year and male horses exhibited significantly higher infection risks, with crude prevalence ratios (PRs) of 4.47 and 2.28, respectively, while prevalence did not differ statistically across rearing modes (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.182). Eighteen genotypes were identified: 11 known (D, horse1, Peru8, Type IV, EbpC, CAF1, GX3, HNR\u2010VI, SHWR5, SYSWR18, SYSWR23) and seven novel (HRBM1, KDM1, KDM2, QQHRM1, QQHRM2, QQHRM3, WZM1). Genotype D was dominant, accounting for 58.1% (36\/62) of positive isolates, followed by genotype horse1 at 14.5% (9\/62) and genotype EbpC at 3.2% (2\/62). The other eight known genotypes and all seven novel genotypes each had one isolate. All seven novel genotypes clustered within zoonotic Group 1 with all the known genotypes except HNR\u2010VI identified here.
