Parasites in feces of the endemic rattlesnake, Crotalus triseriatus (Serpentes: Viperidae), from Mexican highlands

Artículo científicoThere are few studies about parasitic infections in Crotalus triseriatus (Wagler, 1830), an endemic rattlesnake from the highlands of central Mexico. This species occupies several habitats, from conserved forested regions to heavily impacted landscapes. To increase the parasitological knowledge of this reptile species without impacting populations, we obtained fecal samples of 16 rattlesnakes between 2012 and 2014 from Toluca Valley, Mexico. By using flotation technique, we found oocysts of Eimeria sp. and eggs of Capillariidae sp. The most frequent parasite was Eimeria sp. (62.5%). This study provides the first records of occurrence of parasites in reptilian feces from Mexico. Our results may be important for wildlife conservation purposes, for example, they could indicate of the population health of this species during processes of translocation

Endohelminth parasites of seven goodein species (Cyprinodontiformes: Goodeidae) from Lake Zacapu , Michoacán, Central Mexico Plateau

A total of 11 parasitic endohelminth taxa were found in 7 freshwater fish species of the subfamily Goodeinae in Zacapu Lake, Michoacan, Mexico. Six were adults (Margotrema cf. bravoae, Phyllodistomum sp., Saccocoelioides sogandaresi, Rhabdochona lichtenfelsi, Bothriocephalus acheilognathi and Caryophillidae gen. sp.), while the remaining 5 taxa (Clinostomum complanatum, Posthodiplostomum minimum, Tylodelphis sp., Eustrongylides sp. and Polymorphus brevis) were larvae. The taxa S. sogandaresi, Tylodelphis sp., and R. lichtenfelsi reached the highest levels of prevalence and mean abundance among all hosts, while the cestodes B. acheilognathi and Caryophillidae gen. sp. showed the lowest values. This study contributes with the inventory of the freshwater fish helminth fauna in Central Mexico Plateau, and particularly with the previous work that has been done with Goodeinae, a subfamily of freshwater fishes endemic to that part of the country
