Helminths ofDermatonotus muelleri(Anura: Microhylidae) from Northeastern Brazil

Abstract

The helminth fauna associated with Muller's termite frog, Dermatonotus muelleri, from the southern region of Ceará State, Brazil, was studied. The species richness was 6 helminth taxa, including cystacanths of Acanthocephala and 5 nematode species: Aplectana membranosa, Parapharyngodon silvoi, Raillietnema spectans, larvae of Physaloptera sp., and an unidentified nematode. The overall prevalence was 88.6%, with an average intensity of infection of 123.7 ± 26.3. The nematode Raillietnema spectans presented the highest prevalence and was the most abundant ( d = 0.670). Host body size did not influence the intensity of infection nor the richness of helminth species. This study increases the body of knowledge about the diversity of helminth fauna associated with Dermatonotus muelleri from northeastern Brazil, extending the record of hosts and the geographic distribution of these helminth species.

Nematodes of Proceratophrys ararype (Anura: Odontophrynidae), an endemic frog from the Araripe Plateau, northeastern Brazil

“…Oswaldocruzia mazzai have been shown to infect a variety of anuran hosts (e.g., Campião et al 2014, Teles et al 2015, Alcantara et al 2018, Oliveira et al 2019) but our study is the first to record a species of the genus Proceratophrys as a host of O. mazzai. The low host specificity is usual for some groups of helminths (Campião et al 2015, Oliveira et al 2019.…”

“…The parasite Raillietnema spectans was initially described in the large intestine of leptodactylids and bufonids (Alcântara et al 2018), and it has been registered for several other species: Rhinella crucifer (Wied-Neuwied, 1821), R. icterica and Leptodactylus latrans (Campião et al 2014), Pleurodema diplolister (Peters, 1870) (Teles et al 2015), Physalaemus albifrons (Spix, 1824), P. cicada Bokermann, 1966 P. cuvieri Fitzinger, 1826 (Oliveira et al 2019), and Dermatonotus muelleri (Boettger, 1885) (Alcantara et al 2018). This parasite is known to presents a direct life cycle and transmission that occurs via ingestion or penetration of larvae in the skin (Anderson 2000).…”

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

“…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.…”

Helmintos Asociados Con 15 Especies De Anuros De La Meseta De Ibiapaba, en El Noreste De Brasil

“…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).…”
