“…Results for L. brownorum, the mostly aquatic host that we examined in this study and those reported for the terrestrial hosts C. marinus and C. valliceps in Yucatán (Espinola-Novelo and Guillén-Hernández, 2008) strongly differ from results reported in a study which examined specimens of both terrestrial species and 2 aquatic (L. berlandieri and L. vaillanti) species closely related to L. brownorum from Los Tuxtlas, Veracruz (Guillén-Hernández, 1992;Guillén-Hernández, et al 2000). These fi ndings suggest that digeneans species are an important component which structures the parasite community of amphibians in Veracruz, while in Yucatán nematodes appear to take their place as we found them to be more species-rich and abundant.…”

“…The widespread distribution of fi nal hosts of M. temperatus suggests the presence of a species complex which needs further research. Numerous studies have shown that in general more digeneans species are found in amphibians with either aquatic or semiaquatic habits, while nematode species are more common in terrestrial amphibians (Aho, 1990;Guillén-Hernández et al, 2000;Pérez-Ponce de León et al, 2000;Paredes-Calderón, et al, 2004;Espínola-Novelo and Guillén-Hernández, 2008). Overall, results from this work contradict these fi ndings; nematode species richness and mean abundance in L. brownorum were greater compared to that of digeneans in 2 of the localities (Table 2).…”

Between July 2004 and June 2005, 84 specimens of Lithobates brownorum (Sanders, 1973) were collected and examined for helminths. Hosts came from 3 localities in the state of Yucatán, Mexico: Celestún (n= 35), Lagunas de Yalahau (n= 33), and Ría Lagartos (n= 16). Twelve helminth taxa were found: 7 nematodes, 4 digeneans, and 1 acanthocephalan. With the exception of Haematoloechus fl oedae and Megalodiscus temperatus, all helminth taxa found have a Neotropical distribution. Our results differ from those obtained in previous studies dealing with amphibians in Mexico because we found higher richness and abundance of nematodes than digenean species. The relatively low mean intensity and mean abundance values reached by digenean species in this study may be related to the generalist host diet and with the vagility of frogs (from the aquatic to the terrestrial environment or vice versa).

“…In the region of Los Tuxtlas, three additional species of Gorgoderina have been reported – namely, Gorgoderina festoni Mata-López & León Règagnon, 2005, Gorgoderina parvicava (Travassos, 1922) and Gorgoderina sp. (reported as Gorgoderina attenuata (Stafford, 1902) (Guillén-Hernández et al ., 2000; Paredes-Calderón et al ., 2004; Mata-López & León-Règagnon, 2005). The second morphotype, Cystocercous cercaria type II, was nested within a group of species of Phyllodistomum , with high nodal support value; it appears as sister taxon of P. inecoli .…”

Morphological and molecular assessment of the diversity of trematode communities in freshwater gastropods and bivalves in Los Tuxtlas tropical rainforest

Trematode life cycles involve molluscs as first intermediate hosts. The identification of trematodes based on the morphology of cercariae released from molluscs is challenging because the identification relies on adult forms obtained from their definitive hosts. Several studies have recently genetically characterized these larval forms establishing a link with adults sampled from their vertebrate hosts, allowing their identification at species level. In Los Tuxtlas tropical rainforest, in south-eastern Mexico, 57 species of trematodes have been reported from wildlife vertebrates; however, studies evaluating the diversity of trematode cercariae in molluscs are lacking. Here, we studied 11 species of molluscs to assess the diversity of cercariae in two lakes of Los Tuxtlas, Veracruz, Mexico; six of the 11 species were infected. Twelve cercarial morphotypes were collected and characterized morphologically. Sequences of the 28S ribosomal RNA gene were generated to allocate each morphotype into a family using the most recent phylogenetic classification of the Digenea as a framework; molecular work revealed 16 genetic lineages; some cercariae were identified up to genus (Apharyngostrigea, Ascocotyle, Centrocestus, Echinochasmus, Lecithodendrium and Posthodiplostomum), and some to species levels (Gorgoderina rosamondae, Langeronia macrocirra, Oligogonotylus manteri and Phyllodistomum inecoli) based on their phylogenetic position within the tree, and the genetic distance with respect to other sequenced congeners. Therefore, the cercarial morphotypes in the present study represent at least 16 putative species. Our study contributes to a better understanding of the trematode diversity in an area of high vertebrate species diversity, and to the knowledge of trematode life cycles.

“…The number of studies carried out on helminth parasites of amphibians and reptiles from Mexico has increased considerably in the last 15 yr. Those studies generally have covered topics such as taxonomic record of helminth species in amphibians and reptiles from a specific geographic area (Guill´en-Herna´ndez et al, 2000; P´erez-Ponce de Le´on et al, 2000Le´on et al, , 2001Bursey and Goldberg, 2001;Goldberg and Bursey, 2002, among others), helminth parasites of a particular species of host (ParedesCalder´on et al, 2004;Cabrera-Guzma´n et al, 2007;Esp´ınola-Novelo and Guill´en-Herna´ndez, 2008;Ya´˜nez-Arenas and Guill´en-Herna´ndez, 2010), or the taxonomy of a particular helminth species (Le´on-R`egagnon and Brooks, 2003;RazoMendivil et al, 2004;Mata-L´opez and Le´on-R`egagnon, 2006;Le´on-R`egagnon, 2010;Mart´ınez-Salazar and Le´on-R`egagnon, 2010). As a result of these studies, a significant number of new species of different taxonomic groups have been described.…”

Two new species of Parapharyngodon Chatterji, 1933, parasitizing 3 species of hylid frogs (Diaglena spatulata, Triprion petasatus, and Trachycephalus typhonius) from Mexico are described. The 2 new species share the presence of a gubernaculum with Parapharyngodon lamothei and belong to the group of those species with short spicule; both differ from the remaining species of the genus in the papillar pattern on ventrolateral and dorsal lips and in the thickness of cuticular annulations and cuticular ornamentation in the female specimens. These are the third and fourth reports of Parapharyngodon spp. parasitizing hylid frogs. In addition to the egg characteristics, we propose that length of the lateral alae is also a taxonomically relevant feature to differentiate species of the genus. A bibliographic review of all species historically assigned to Parapharyngodon is given, including those that have been declared species inquirenda, or transferred to other genera and those that are considered valid.
