“…Studies of the parasites of the fish in the Papaloapan basin began in 1954 and are largely taxonomic treatments concentrating mostly on fish in the Los Tuxtlas area and particularly Catemaco Lake, Veracruz (Caballero and Winter 1954;Lamothe-Argumedo 1974Lamothe-Argumedo and Ponciano-Rodrı´guez 1986;Caballero-Deloya 1977;Salgado-Maldonado 1978;Salgado-Maldonado et al 1992, 1998Garcı´a-Prieto 1990;Garcı´a-Prieto et al 1996;Pe´rez et al 1992;Jime´nez-Garcı´a 1993;Moravec 1998;Moravec et al 1998Moravec et al , 2000Moravec et al , 2002aCaspeta-Mandujano et al 1999Salgado-Maldonado 2000, 2001;Scholz et al 2001b;Pa´ez-Rodrı´guez et al 2002;Aguilar-Aguilar et al 2003a;Mendoza-Franco et al 2003b). More recent studies addressing the role of freshwater fishes as transmitters of the human gnathostomiasis have been done in the Temascal Reservoir, Oaxaca (Almeyda-Artigas 1991; Almeyda-Artigas et al 1995;Lamothe-Argumedo 1977;Lamothe-Argumedo et al 1989).…”

Helminth parasites in freshwater fish from the Papaloapan river basin, Mexico

et al. 2005

A checklist based on previously published records and original data is presented for the helminth parasites reported in 35 fish species from nine families from the Rio Papaloapan basin, east Mexico. The checklist contains 85 taxa from 39 helminth families. Trematodes and nematodes were the most abundant taxonomic groups. The helminth fauna in the fish of the Papaloapan River basin predominantly consists of Neotropical species that are largely autogenic. The introduced species Centrocestus formosanus was the most widely distributed helminth, infecting 16 host species. Ten of the recorded helminth species have only been found in fish from the Papaloapan. This inventory contributes 157 new host records, and reports the presence of 30 helminth species in the Papaloapan for the first time . This inventory shows the richness of helminth parasite species in the fish of the Papaloapan River basin in comparison with the other hydrological basins in Mexico. It also demonstrates that this fauna is typically Neotropical and quite similar to that from the neighboring basins of the Grijalva-Usumacinta system and the Yucatan Peninsula. The data also suggest highly effective transmission between environments within the same basin and that the regional parasite fauna is strongly influenced by fish community composition.

“…There is intraspecific variation in the morphological measurements of L1 of M. cichlasomae in different species of definitive hosts. The mean length of L1 larvae (134.00 ± 11.63) from M. cichlasomae females from C. urophthalmus in the present study was longer than that of M. cichlasomae L1 from Xiphophorus helleri Heckel, 1848 (Cyprinodontiformes: Poecilidae) (100 μm long) (Moravec et al , 1998). This difference in total length can be associated with intraspecific variability given the different species of definitive hosts.…”

Molecular evidence linking the larval and adult stages of Mexiconema cichlasomae (Dracunculoidea: Daniconematidae) from Mexico, with notes on its phylogenetic position among Dracunculoidea

et al. 2018

We describe the larval developmental stages and life cycle of the dracunculid nematode Mexiconema cichlasomae in both the intermediate, Argulus yucatanus (Crustacea: Branchiura), and definitive hosts, Cichlasoma urophthalmus (Perciformes: Cichlidae), from the Celestun tropical coastal lagoon, Yucatan, Mexico. The morphological analyses showed significant differences between the total length of L1 found in M. cichlasomae gravid female and L2-L3 in A. yucatanus. This result indicates that the M. cichlasomae larval development occurs in the intermediate host. We obtained sequences from the small subunit (SSU) ribosomal marker from larval stages of M. cichlasomae in A. yucatanus and adult nematodes in C. urophthalmus. Our morphological and molecular results support conspecificity between M. cichlasomae larvae in A. yucatanus and the adult stages in C. urophthalmus. We briefly discuss the phylogenetic position of M. cichlasomae among the Daniconematidae, and provide evidence of the monophyly of the daniconematids associated with branchiurid intermediate hosts. Based on the phylogenetic results, we support the transfer of the Mexiconema genus to the family Skrjabillanidae and do not support the lowering of family Daniconematidae to subfamily.

“…( Pérez-Ponce de León et al 1999 ), and Mexiconema cichlasomae ( Moravec et al 1998 ). However, their presence in elasmobranchs is considered accidental; elasmobranchs can be infected through 2 ways: 1) ingestion of prey acting as intermediate hosts for almost completely developed larvae and 2) ingestion of definitive hosts constituting an accidental, probably postcyclic transmission ( Moravec et al 1998 ; Anderson 2000 ; Weaver and Smales 2014 ).…”

A comprehensive and updated summary of the literature and unpublished records contained in scientific collections on the helminth parasites of the elasmobranchs from Mexico is herein presented for the first time. At present, the helminth fauna associated with Elasmobranchii recorded in Mexico is composed of 132 (110 named species and 22 not assigned to species), which belong to 70 genera included in 27 families (plus 4 incertae sedis families of cestodes). These data represent 7.2% of the worldwide species richness. Platyhelminthes is the most widely represented, with 128 taxa: 94 of cestodes, 22 of monogeneans and 12 of trematodes; Nematoda and Annelida: Hirudinea are represented by only 2 taxa each. These records come from 54 localities, pertaining to 15 states; Baja California Sur (17 sampled localities) and Baja California (10), are the states with the highest species richness: 72 and 54 species, respectively. Up to now, 48 elasmobranch species have been recorded as hosts of helminths in Mexico; so, approximately 82% of sharks and 67% of rays distributed in Mexican waters lack helminthological studies. The present list provides the host, distribution (with geographical coordinates), site of infection, accession number in scientific collections, and references for the parasites. A host-parasite list is also provided.
