“…Although there is a lack of detailed biology on this parasite, it is known to have a direct or indirect life cycle, with the former being the most usual (Santos et al 2010). The infection occurs on land through skin penetration or ingestion of infected preys (Mati & Melo 2014, Sulieman et al 2015. Even though this nematode infects several amphibian species (Campião et al 2014, Sulieman et al 2015, this is the first record of the genus Strongyloides acting as a parasite for species of the Odontophrynidae family.…”

Parasites are an important component of the global biomass, having significant roles in several regulatory mechanisms in the ecosystem. Parasitism is one of the most common ecological interactions on the planet. Studies have shown that the helminth fauna of only 8% of amphibian species in Brazil have been studied, and this percentage is lower for the Odontophrynidae family, with only four of the 50 species kown to occur in Brazil having been investigated. Here, we present the helminth fauna of Proceratophrys ararype, an anuran endemic to the “Brejo de Altitude” Chapada do Araripe (Araripe Plateau), northeastern Brazil. The infection parameters analyzed were prevalence, mean intensity of infection and mean abundance of parasites. We used the Pearson’s linear correlation coefficient to check the correlations between the abundance of the parasites with the snout-vent length (SVL) of hosts. To verify the degree of aggregation of parasites in hosts, we used the dispersion index. Out of 40 specimens examined, 19 specimens were infected with at least one parasite. The overall prevalence was 47.5% with a mean infection intensity of 18.93 ± 10.77. The endoparasitic community associated with P. ararype consisted of six species of parasites, with Falcaustra mascula having the highest prevalence (25%). Most parasites had a uniform dispersion index in the hosts and their abundance was unrelated to host size. Here, we also present a compilation of all parasites associated with host species of the genus Proceratophrys from South America. Overall, we found 23 species of parasites associated with five host species (P. ararype, P. appendiculata, P. boiei, P. cristiceps, P. mantiqueira). Of these, two species of parasites (Oswaldocruzia mazzai and Strongyloides sp.) represent new records for the genus Proceratophrys. Our results demonstrate the lack of studies on amphibian helminth fauna and fill an important knowledge gap on the diversity of parasites of Proceratophrys ararype, an endemic frog from the Araripe Plateau, northeastern Brazil.

“…Although the life cycle of Strongyloides is not known, it can be considered a direct or indirect cycle, the first being the most common (Santos et al, 2010). Infection occurs on land through skin penetration or ingestion of infected prey (Mati & Melo, 2014;Sulieman et al, 2015). Although there are several records of this nematode infecting amphibian species (Campião et al, 2014;Sulieman et al, 2015;Mascarenhas et al, 2021), this is the second record of the genus Strongyloides acting as a parasite for species of the Odontophrynidae family and the first for O. carvalhoi.…”

La familia Odontophrynidae comprende 40 especies de anuros ampliamente distribuidas en América del Sur, desde Brasil hasta Argentina y Paraguay. Odontophrynus carvalhoi Savage & Cei, 1965, especie de tamaño mediano, hábitos terrestres y reproducción explosiva, es uno de los representantes de esta familia. A pesar de su extensa distribución, los datos sobre su historia natural son limitados, y la información publicada se centra principalmente en patrones de actividad, dieta y comportamiento defensivo. En este estudio, presentamos datos sobre la composición y patrones de infección de endoparásitos asociados con O. carvalhoi en un bosque relicto en el estado brasileño de Ceará. La comunidad de parásitos estuvo compuesta por 11 especies, siendo Aplectana hylambatis (76,67%) y Oswaldocruzia mazzai (79,49%) las más prevalentes. Además, reportamos nuevas ocurrencias de especies de parásitos para O. carvalhoi, contribuyendo al conocimiento de la fauna parasitaria en la región Neotropical. Estos hallazgos subrayan la importancia de la investigación parasitológica para una comprensión integral de la ecología y biología de esta especie de anfibio.

“…Several studies have been carried out on amphibians in some area in Southern Nigeria including Southern Eastern region (Akani et al, 2003), Guinea savanna at New Bussa (Aisien et al, 2004a), Gelegele Forest Reserve, in South Western Nigeria (Aisien et al, 2009). For instance, Aisien et al (2009) Furthermore, the helminthparasites of amphibians have also been reported from several locations in Nigeria (Aisien et al, 2003(Aisien et al, , 2004b2009;Aisien et al, 2015;Imasuen et al, 2012) and Sudan (Sulieman et al, 2015). Due to the economic importance of amphibians there is the need to ascertain the parasites associated with them.…”

The specimens were dissected and examined following standard protocol. Results revealed the presence of 3 Classes of helminthes distributed into 2 cestodes, 4 nematodes and 1 trematode. The prevalence for each parasite wasCepaloclamyssp (10.3%), Pentastimidsp (6.89%) (cestodes), Oxyuridsp (6.89%), Applectanamakintoshi(3.44%), (31.0%), Cosmocera ornate (10.3%) (nematodes), and Mesocolium monas (17.2%) (trematoda). The mean intensity of infection were <1 except for Amplicaecumafricanum(7.14) a nematode, and Mesocolium monas (13.86) a trematode. Hence, there is the need for a close study of these parasites to ascertain their level of public health importance with regard to potential transmission to humans that feed on the definite predators of the amphibians.
