In this survey, we inventoried the helminths of heteromyid and cricetid rodents captured in Yucatan Peninsula from 2017 to 2019. Helminths were identified using morphological techniques (clearing, staining, scanning electron microscopy). Also, 28S rRNA gene individuals several helminth taxa was successfully amplified sequenced. To confirm identification at generic level, some cases specific genealogical relationships parasites, phylogenetic analyses performed with new sequences. We 22 species including three trematodes (Brachylaimidae, Dicrocoeliidae, Microphallidae), five cestodes (Davaineidae, Hymenolepididae, Taeniidae), 14 nematodes (Trichuridae, Ancylostomatidae, Ornithostrongylidae, Heligmonellidae, Oxyuridae) Heteromys gaumeri (Heteromyidae), Ototylomys phyllotis, Oligoryzomys fulvescens, Peromyscus yucatanicus, Sigmodon toltecus, Reithrodontomys gracilis (Cricetidae). The overall frequency infection small 84.1% (143/170); all specimens H. gaumeri, S. toltecus Ol. fulvescens infected helminths. total, provided 46 sequences 17 Seven are likely undescribed species, six reported for first time Mexico, 12 host records Americas.
