“…Thus, the higher prevalence, abundance and intensity of infection of turtles from Portil may be related to the higher frequency of plant matter in the diet of these turtles than in those from Acebuche (N. Perez-Santigosa, unpublished PhD.). Infection intensities could be also related with the abundance of intermediate hosts in each locality as has been previously described (Esch and Gibbons, 1979a;Esch et al, 1979b).…”

We report the prevalence and diversity of helminth parasites found in native turtles Mauremys leprosa and Emys orbicularis from three localities in southwestern Spain and we describe the helminth communities of exotic turtles Trachemys scripta elegans coexisting in the wild with both native turtle species. Five nematodes species were identified, of which Serpinema microcephalus was the only species common between two localities, although infection parameters were different between them. This is the first report of cross transmission of S. microcephalus and Falcaustra donanaensis from native to exotic turtles and the first report of genus Physaloptera in turtles of the Palearctic Region. Continuous releasing of exotic pet turtles in wildlife ecosystems increases the risk of parasite introductions and, consequently, potential transmission to native species, and highlights the impending need for regulation of pet turtle trade in Europe..

“…In this context, the helminth assemblage composition and differences in parasite loads of S. contortus, C. emydidius, F. affinis, D. renale and T. corti between individuals from rural and urban environments may be related to the availability of intermediate and/or paratenic hosts, which should be ingested to continue the helminth cycle. Esch et al (1979), upon analyzing the diversity of intestinal helminth Trachemys scripta (Thunberg in Schoepff, 1792) (Emydidae) in six habitats thermally influenced by a nuclear reactor noted greater diversity as to chemical and physical characteristics in more stable places, suggesting that diversity may result from the complexity of the parasiteʼs life cycle. In order to evaluate diet influence on helminth acquisition, one should also take into account that the diet of freshwater turtles can vary in relation to maturity and gender (Teran et al, 1995;Souza, 2004;Brasil et al, 2011;Hahn et al, 2014).…”

The assemblage of helminths of Trachemys dorbigni was analyzed according two environments (rural and urban) and according to host’s gender. Thus, the helminths found were: Spiroxys contortus (Rudolphi, 1819), Falcaustra affinis (Leidy, 1856), Camallanus emydidius Mascarenhas & Müller, 2017, Dioctophyme renale (Goeze, 1782) (larvae), Eustrongylides sp. (larvae) (Nematoda), Telorchis corti (Stunkard, 1915), Telorchis achavali Mañé-Garzón & Holcman-Spector, 1973, Telorchis spp. (Digenea), Polystomoides rohdei Mañé-Garzón & Holcman-Spector,1968 and Neopolystoma sp. (Monogenoidea). Parasitological indices suggests that S. contortus, F. affinis, C. emydidius, T. corti and P. rohdei are species common in helminth assemblage of T. dorbigni in southern Brazil. Infection by Dioctophyme renale is typical of the urban area and suggest relation with eutrophication process and feedback of parasitic cycle in the freshwater urban environment. Parasitological indices of Neopolystoma sp. and T. achavali suggest to be occasional infections; whereas infection by Eustrongylides sp. could be considered accidental. About Telorchiidae, there was no co-occurrence of the species of this group for the examined hosts. In relation to host’s gender, it was observed that infections by S. contortus, F. affinis, C. emydidius and T. corti had higher rates in females, showing a more intimate association with the females of T. dorbigni. The results suggest that human impact on the environment could affect the infrapopulacional dynamics of parasite species influencing the presence and rates of infection of helminths or exacerbating heterogeneities related to host’s gender.
