“…Euclydes et al (2021) studied the nematode diversity of parasite communities of Atlantic species of anurans and found a positive correlation of habitat use with the variability in the parasite species composition and their functional diversity. They suggested that the higher functional diversity of parasite communities in terrestrial hosts may be related to the fact that nematodes are the main components of helminth diversity in amphibians and they are transmitted directly through contact with the soil, as pointed out by several studies (Campião et al , 2014; Hamann & González, 2015; da Silva et al , 2017; Gómez et al , 2020). Additionally, although the life cycle of most species of Oswaldocruzia remains unstudied, some works have demonstrated that the life cycles of some species are direct and well known (Anderson et al , 2000), and the greater vagility of terrestrial amphibians compared to arboreal species increases the possibility of contact with a higher diversity of parasites, as pointed out by Poulin (2007).…”

The genus Oswaldocruzia Travassos, 1917 includes approximately 90 species that are parasitic on amphibians and reptiles around the world, of which 43 occur in the neotropical region. However, molecular data supporting the taxonomic status of most species of the genus are scarce, and their phylogenetic relationships remain unknown. Using specimens of four molineid taxa (Oswaldocruzia belenensis Santos, Giese, Maldonado Jr. and Lanfredi, 2008; Oswaldocruzia chabaudi Ben Slimane & Durette-Desset, 1996, Oswaldocruzia chambrieri Ben Slimane & Durette-Desset, 1996 and Kentropyxia hylae Feitosa, Furtado, Santos and Melo, 2015) from amphibian hosts collected in different regions of Pará, Brazil, we conducted morphological studies, molecular analyses and phylogenies (maximum likelihood and Bayesian inference) using the cytochrome c oxidase subunity I (Cox1) gene. The newly generated sequences were compared with those of ten publicly available Cox1 sequences of Oswaldocruzia from Mexico. Our findings demonstrated significant differences between the sequences of amazonian specimens and sequences from specimens collected in Mexico, and we suggest that host–parasite cospeciation or habitat use might be related to molineid evolution in amphibian hosts. Additionally, this work presents new hosts and new geographical records for species of Oswaldocruzia from the neotropics.

This study aimed to comprehensively update and expand the knowledge on the diversity and richness of helminth parasites found in Peruvian amphibians. A systematic search was conducted across primary databases, encompassing both indexed and non-indexed articles, to compile the most recent data. As of the present study, a total of 83 distinct helminth taxa have been documented in association with 78 anuran species of the order Anura, marking a 176.7% increase from previously recorded figures. Nematodes exhibited the highest species richness, totalling 52 taxa (62.65%), followed by trematodes (21 taxa, 25.3%), acanthocephalans and cestodes (4 taxa each, 4.8%), and monogeneans (2 taxa, 2.4%). The overwhelming majority (85.5%) of the collected parasites (71 taxa) were identified as mature helminths, with the remaining 14.5% (12 taxa) in their larval stages. Notably, Cosmocerca brasiliense Travassos, 1925 (Cosmocercidae), and Physaloptera sp. (Physalopteridae) were the most prevalent nematodes, having infected the broadest range of host species. Rhinella marina Linnaeus, 1758 (Bufonidae), emerged as the anuran host with the highest diversity, harboring 17 distinct helminth species. These findings underscore the crucial role of helminth parasites in shaping amphibian ecosystems and their significance as bioindicators of environmental health. Protecting both amphibian hosts and their associated helminth parasites is paramount, as it is intrinsically linked to the preservation of ecological equilibrium within these ecosystems.
