Patterns of helminth infections inRattus rattusandMus musculusfrom two Mayan communities in Mexico

Abstract

The black rat Rattus rattus and the house mouse Mus musculus are two commensal rodent species that harbour and shed zoonotic pathogens, including helminths. The aim of this survey was to study the helminth community and the patterns of infections in R. rattus and M. musculus from two Mayan communities in Mexico. Gastrointestinal helminths were isolated from 322 M. musculus and 124 R. rattus, including Gongylonema neoplasticum, Hassalstrongylus aduncus, Hassalstrongylus musculi, Hydatigera taeniaeformis metacestode, Hymenolepis diminuta, Nippostrongylus brasiliensis, Oligacanthorhynchidae gen. sp., Syphacia muris, Syphacia obvelata, Rodentolepis microstoma and Trichuris muris. The overall richness of helminths was seven in R. rattus and six in M. musculus. The results of generalized linear models showed that juvenile rodents had lower probabilities of being infected with G. neoplasticum, H. taeniaeformis and H. musculi than adult rodents. A positive association between the prevalence of S. muris and rat abundance was found. The intensity of infection with S. muris was higher in the rainy season than in the dry season; the opposite result was found for H. musculi infection. Male R. rattus harboured more S. muris specimens. The intensity of infection with T. muris was inversely associated with mouse abundance. The presence of the zoonotic H. diminuta, as well as H. taeniaeformis and R. microstoma in rodent populations indicates that there is risk of transmission, and that their entire life cycle occurs in the study area.

Patterns of Gastrointestinal Helminth Infections in Rattus rattus, Rattus norvegicus, and Mus musculus in Chile

“…In addition to the five mentioned helminthic species, H. spumosa, A. tetraptera, N. brasiliensis, and G. neoplasticum have been reportedly found in Rattus spp. and M. musculus elsewhere in both laboratory and feral specimens (8,42,(44)(45)(46)(47). The enemy release hypothesis states that invasive animals present with fewer parasite species than in their original territory (48) given the small sample size of translocated animals, the loss of parasites during the translocation process, and/or the adaptation of the parasite to the new territory (49).…”

Roedores comensales y su implicación en la salud pública en Yucatán

“…A pesar del impacto negativo de dichos roedores, todavía existen vacíos sobre el conocimiento de su biología y rol en la transmisión de enfermedades, particularmente en regiones tropicales, ya que la mayoría de la información proviene de áreas templadas de Estados Unidos de América e Inglaterra. En Yucatán, se han realizado investigaciones científicas enfocadas principalmente en estudios poblacionales de roedores (e.g., Panti-May et al 2016, 2018ab) y sobre la identificación de agentes zoonóticos en áreas rurales y urbanas (e.g., Panti-May et al 2021). En este contexto, el objetivo de este trabajo es presentar un análisis descriptivo sobre aspectos biológicos básicos del ratón casero y la rata negra en áreas tropicales y también revisar sus implicaciones en salud pública en Yucatán, México.…”
