“…Previously, only C. vulpis was morphologically identified in red foxes from Romania (52), and is now morphologically and molecularly confirmed in two mustelid species, M. martes and M. foina. In red foxes, the abundance of C. vulpis has a strong positive relationship with the presence of wetlands, and environmental factors mostly act on the intermediate hosts, regulating the distribution pattern (52).…”

Species of genus Crenosoma have a wide distribution and are reported in Europe, the Americas, and Asia. Currently, the genus includes 14 nominal species, out of which 9 are parasitic in mustelids. Two species are mostly reported in mustelids from Europe, namely C. melesi and C. petrowi. Up to now, no genetic sequences are deposited in GenBank for any of the two. The aims of this study were to investigate the distribution, prevalence, and diversity of Crenosoma spp. infecting mustelids in Romania and to genetically characterize the species. Mustelids (n = 247) were collected over a period of 7 years from different locations in Romania and the respiratory tract was removed and examined for nematodes. Detected nematodes were morphologically identified and fragments of two genes were sequenced. Sampled mustelids included Eurasian badger, Meles meles (n = 102), Eurasian otter, Lutra lutra (n = 20), beech marten, Martes foina (n = 36), European pine marten, Martes martes (n = 5), steppe polecat, Mustela eversmanii (n = 1), European mink, Mustela lutreola (n = 1), least weasel, Mustela nivalis (n = 2), European polecat, Mustela putorius (n = 78), and marbled polecat, Vormela peregusna (n = 1). Nematodes from Eurasian badgers were morphologically identified as C. melesi (n = 13, 12.74%) and C. petrowi (n = 3, 2.94%). Nematodes from the beech martens were identified as C. petrowi (n = 6, 16.66%), C. vulpis (n = 1, 2.78%) and Crenosoma spp. (n = 3, 8.33%). Co-infections with two Crenosoma species were detected in one beech marten (C. petrowi + C. vulpis, n = 1, 2.77%) and in one European pine marten [C. petrowi + C. vulpis (n = 1, 20%)]. Two genes of Crenosoma melesi and C. petrowi were partly sequenced for the first time. We report new host-parasite associations for M. martes and C. vulpis. However, further studies are needed in order to determine the host-parasite associations and to improve the understanding of the epidemiology of Crenosoma nematodes.

“…The host and environmental factors influencing parasitic abundance were evaluated by mean of a Generalised Linear Model (GLM), with Poisson distribution family. Attending to the home range of the fox ( Deak et al, 2020 ), environmental variables were calculated for a 1 km buffer (400 ha) from the geographic location of origin of each individual using QGIS (3.16.11) software ( QGIS Development Team, 2021 ). The environmental variables were grouped into three categories: climatic variables, spectral index and land uses ( Table 2 ).…”

“…Likewise, individuals with high body mass can harbor more parasites since a larger habitat favor parasite colonization, while individuals with low body condition can exhibit reduced immune competence related to nutrients deficiency and an increase in parasitosis (Wilson et al, 2002;Morand, 2015). In addition, environmental characteristics that influence parasitic infections include altitude, climate (e.g., temperature, humidity), habitat quality, among others (Wells et al, 2007;Barelli et al, 2021;Deak et al, 2020;Kiene et al, 2021). Effects of helminths and protozoa infections on rodents living in human-modified habitats can be intensified with detrimental impact at host population scale (Santicchia et al, 2015).…”

Gastrointestinal parasites are well-documented in small mammals from north-central Chile, but little is known about endoparasites of rodents in southern Chile. A survey was conducted between January and February 2018 to evaluate gastrointestinal parasites and risk factors of wild rodents that live in rural areas in Northern Chiloé Island, Chile. A total of 174 fecal samples from rodents of six native and one introduced species were collected and examined using the Mini-FLOTAC method. Also, 41 individuals of four native wild rodent species were examined furtherly to determinate adult parasites from gastrointestinal tracts. The overall prevalence of endoparasites was 89.65% (156). Helminth egg types included: Rodentolepis spp., Capillariidae, Trichuris sp., Syphacia sp., oxyurid-type eggs, Strongyloides sp., Spirurid-type eggs, Strongilid-type eggs, Moniliformis sp., and an unidentified nematode egg and larvae. Protozoa comprised coccidia, amoeba, and unidentified cysts. From necropsies, adult parasites involved Syphacia sp. Trichuris sp., Protospirura sp. and Physaloptera sp. In Abrothrix olivacea, individuals with low-body-mass index exhibited reduced infection probability for Spirurid-type and Strongilid-type eggs. Some parasites in this study may affect human health. In rural settings where environmental conditions are changing, more research should be undertaken to understand parasitic infections in wildlife and implications for public health and conservation.
