A checklist of the parasitic helminths of cricetid and heteromyid rodents in Mexico

Abstract

We present an updated checklist of helminth species infecting cricetid and heteromyid rodents (Rodentia: Cricetidae and Heteromyidae) distributed in Mexico. For each helminth record, we include information on helminth taxonomy, location within the host, life stage, host associations, collection localities, citation, and museum collections, when available. We recorded more than 73 helminth species from 47 host species distributed across 21 states in Mexico. The present list represents the most up-to-date knowledge of helminth species infecting cricetid and heteromyid rodents in Mexico. En el presente trabajo se da a conocer el registro actualizado de los helmintos parásitos que se encuentran en roedores cricétidos y heterómyidos (Rodentia: Cricetidae y Heteromyidae) distribuidos en México. Para cada registro de helminto se incluye la información taxonómica, su localización en el huésped así como su estado de desarrollo y asociación con éste; además de proveer los datos del lugar de colecta, la citas bibliográficas donde han sido registrados y los datos de la colección donde se encuentran depositados, siempre y cuando los datos estén disponibles. Se enlistan más de 73 especies de helmintos que parasitan a 47 especies de huéspedes, distribuidos en 21 estados de la República Mexicana. El presente listado representa el conocimiento más actualizado de las especies de helmintos que infectan roedores cricétidos y heterómidos en México.

Helminths of small rodents (Heteromyidae and Cricetidae) in the Yucatan Peninsula, Mexico: an integrative taxonomic approach to their inventory

“…In Mexico, metacestodes of Hyd. taeniaeformis have also been reported in the liver of cricetid and murid rodents (Preisser & Falcón-Ordaz 2019;Panti-May et al 2021). However, the length of large hooks of Hyd.…”

“…Particularly, in Yucatan, only 11 helminth taxa have been recorded in 4 of 13 heteromyid and cricetid rodent species: 3 in H. gaumeri (Panti-May & Robles 2016;Panti-May et al 2018), 4 in P. yucatanicus (Panti-May et al 2018), 3 in Sigmodon toltecus (de Saussure) (Panti-May et al 2018) and 1 in Ototylomys phyllotis Merriam (Chitwood 1938). In Campeche and Quintana Roo, no helminths have been recorded in small rodents (Preisser & Falcón-Ordaz 2019). This clearly shows that the inventory of the helminths parasitizing wild small rodents is incomplete in the Yucatan Peninsula.…”

“…Studies on helminths parasitizing wild small rodents in Mexico began in the late 1930s (Chitwood 1938). Several decades later, numerous studies have investigated the helminths of small rodents throughout the country (see García-Prieto et al 2012;Preisser & Falcón-Ordaz 2019). However, the reported list of helminth species of these rodents is incomplete due to the limited number of hosts examined and surveys conducted in some regions.…”

“…However, the reported list of helminth species of these rodents is incomplete due to the limited number of hosts examined and surveys conducted in some regions. The most recent checklist of the helminths of small rodents in Mexico reported 87 taxa of helminths in 47 of 190 cricetid and heteromyid rodent species from 21 Mexican states (Preisser & Falcón-Ordaz 2019). Particularly, in Yucatan, only 11 helminth taxa have been recorded in 4 of 13 heteromyid and cricetid rodent species: 3 in H. gaumeri (Panti-May & Robles 2016;Panti-May et al 2018), 4 in P. yucatanicus (Panti-May et al 2018), 3 in Sigmodon toltecus (de Saussure) (Panti-May et al 2018) and 1 in Ototylomys phyllotis Merriam (Chitwood 1938).…”

Morphological and molecular characterization of Trichuris muris (Nematoda: Trichuridae): studies from two commensal rodent species

“…In Mexico, T. muris has been recorded mainly in commensal rodents such as M. musculus , R. rattus and Rattus norvegicus in the Mexican states of Hidalgo, Mexico City, Tabasco and Yucatan (Panti-May et al , 2021), with the only record from the wild rodent Heteromys irrotatus found in the state of Morelos (Preisser & Falcón-Ordaz, 2019). Meanwhile, in Argentina T. muris has only been recorded in R. rattus found in one city, Corrientes (Gómez Muñoz et al , 2018).…”
