“…Nevertheless, considering the distribution records of the P. pocoto frog, which is mainly found in the Caatinga domain (Silva et al ., 2017) and the results of helminth records associated with amphibians of other species in the biome (Teles et al, 2014, 2015; 2018a, b; Araujo-Filho et al, 2015; Lins et al, 2017; Alcantara et al, 2018; Müller et al, 2018; Silva et al, 2018; Amorim et al, 2019; Oliveira et al, 2019; Madelaire et al, 2020), we suggest the potential endemism of Rhabdias pocoto n. sp. in this biome, and considering the unique morphological character and specificity for the right lung of the host, suggest that the new taxon may have strict specificity for this species of host or host family.…”

A new species of Rhabdias (Nematoda: Rhabdiasidae), a lung parasite of Pseudopaludicola pocoto (Anura: Leptodactylidae) from north-eastern Brazil: description and phylogenetic analyses

Rhabdias pocoto n. sp. is herein described from the lungs of the swamp frog Pseudopaludicola pocoto Magalhães, Loebmann, Nogueira, Kokubum, Baptista, Haddad & Garda, 2014, from the Caatinga biome in the state of Ceará, in north-eastern Brazil. The new species is characterized by a body that dilates posteriorly, six small lips (protuberances) and two rounded lateral expansions of cuticular inflation on the anterior end, each containing an amorphous gland-like structure inside and a short and conical tail. Additionally, molecular analysis and comparison of the partial mitochondrial cytochrome c oxidase I sequence of R. pocoto n. sp. revealed genetic divergence between the new species and the sequences of Rhabdias spp. previously deposited in GenBank. Phylogenetic analysis grouped the new taxon into the R. pseudosphaerocephala species complex + R. glaurungi clade. The new discovery represents the 19th species of Rhabdias spp. described in the Neotropical region, the ninth in Brazil and the first species of Rhabdias found parasitizing South American frogs of the genus Pseudopaludicola, as well as the first Caatinga biome species of Rhabdias.

“…In Brazil, there are records of O. oxyascaris infecting amphibians of the Leptodactylidae family in the South and Southeast regions (Vicente et al, 1991). In the Northeast of Brazil, the records are restricted to the states of Bahia and Pernambuco (Teles et al, 2015). This species is identified by having a mouth with three lips, muscular esophagus followed by a glandular ventricle, equal spines, and gull-wing and caudal wings absent (Vicente et al, 1991) (Figs.…”

Helminth community dynamics in a population of Pseudopaludicola pocoto (Leptodactylidae: Leiuperinae) from Northeast-Brazilian

2018

SummaryClimatic variation in low latitudes influences the dynamics and structure of parasite communities. Environmental changes caused by dry and rainy seasons alter prevalence and abundance of endoparasite communities. In addition to providing a list of the helminth species associated with the swamp frog Pseudopaludicola pocoto, this study aimed to investigate the effects of rainfall and temperature on parasitological descriptors of helminths associated with P. pocoto in an area of the semiarid zone. A total of 817 swamp frog specimens were collected between 2013 and 2017, with four sampling expeditions during the dry season and four during the rainy season. Environmental parameters of temperature and rainfall were compared to the parasitological descriptors of prevalence, abundance and mean infection intensity of the parasite community using a multivariate linear regression. A richness of eight parasite species was identified, including Nematoda (Rhabdias sp., Cosmocerca parva, Oxyascaris oxyascaris, Physaloptera sp., Brevimulticaecum sp., Spiroxys sp. and unidentified nematode) and Acanthocephala (cystacanths). Rainfall levels had a significant effect on the infection intensity of Rhabdias sp. being the presence of this species higher during the rainy season, whereas no influence of temperature was observed on the helminth community.

“…According to Anderson (2000), parasites with direct life cycles have low specificity and simple mode of transmission that can occur through egg ingestion or larval penetration through the host skin. Moreover, R. spectans and O. mazzai have been recorded infecting several Brazilian anurans, including P. diplolister, Dermatonotus muelleri (Boettger, 1885), Leptodactylus latrans (Steffen, 1815), Rhinella crucifer (Wied Neuwied, 1821), Rhinella icterica (Spix, 1824), L. fuscus, L. mystaceus, Physalaemus albifrons, P. cicada, and P. cuvieri (Campião et al, 2014;Teles et al, 2015;Alcantara et al, 2018;Oliveira et al, 2019).…”

La diversidad de los helmintos en los grupos de huéspedes con gran diversidad de especies como los anfibios anuros siguen estando subrepresentados, especialmente en sitios con condiciones ambientales severas como las regiones áridas y semiáridas. Este conocimiento es necesario para comprender el papel de los parásitos en los diferentes niveles de la organización ecológica. Con el fin de evaluar la composición del parásito una taxocenosis de las especies de anuros, describir la riqueza y diversidad de los helmintos a nivel de componentes y de la infracomunidad; además de evaluar la influencia del tamaño del cuerpo en la abundancia y diversidad de los parásitos, se realizó este estudio. Los anuros huéspedes se recogieron en la Zona de Protección Ambiental (EPA) Bica do Ipu en el semiárido brasileño. Los huéspedes recolectados fueron sometidos a eutanasia y a una necropsia en busca de parásitos. En secuencia, se identificaron los helmintos y se realizaron las pruebas estadísticas. Un total de 15 especies de huéspedes compusieron este estudio y se recogieron 1.216 helmintos con abundancia media (MA) de 12,9 ± 3,38 y intensidad media de la infección (MII) de 25,84 ± 6,44. La riqueza media de helmintos fue de 2,3 ± 0,53 (rango = 6), y la diversidad de helmintos (H) fue de 1,36. La comunidad de componentes de helmintos que infectan a los anfibios huéspedes comprende 13 taxones: dos especies de cestodos, un acantocéfalo, un trematodo y nueve nematodos. El presente estudio contribuye al conocimiento de los helmintos que infectan a los anfibios de la Caatinga brasileña, así como a la comprensión de los patrones de diversidad de las infracomunidades parasitarias asociadas a los anfibios.
