“…Species of the genus Schrankiana have a direct life cycle. This parasite has only been found parasitizing anuran species in the family Leptodactylidae (Campião et al , 2014; González & Hamann, 2014). This is the first record of Schrankiana sp.…”

Helminth community structure of 13 species of anurans from Atlantic rainforest remnants, Brazil

This study aimed to evaluate the community composition and structure of the helminths found in 13 anuran species, and to evaluate whether this parasite community is determined by anuran characteristics. We found that the helminth fauna of the amphibians from five anuran families consisted of 13 taxa and that Cosmocercidae gen. sp. was the most prevalent taxon, followed by Oswaldocruzia subauricularis. Host body size was a determining factor of the composition and structure of the parasitic fauna. Helminth abundance and richness were positively correlated with host body size. The host Leptodactylus latrans had the highest helminth richness (n = 8). The frog Hypsiboas faber had the greatest helminth diversity (H' = 0.711). The mean helminth species richness and diversity differed significantly between host species (P < 0.05). Taken together, our data indicate that, in sympatric species of amphibians, the morphological and behavioural characteristics of the hosts are important for structuring the helminth parasite communities.

“…Leptodactylus bufonius, together with R. major, was the best-studied species in both ecoregions [26,[30][31][32]42,48,49,52,67,70,71,79,81]. Therefore, we emphasize that estimates on parasite species richness are strongly influenced by sampling effort [136].…”

Nematodes of Amphibians from the South American Chaco: Distribution, Host Specificity and Ecological Aspects

2021

View full text Add to dashboard Cite

This is the first review of the nematode parasites of amphibians from Dry Chaco (DC) and Humid Chaco (HC) ecoregions of South America, covering aspects related to their systematics, distribution, host range and ecology, including their life cycles. Of approximately 100 species of amphibians that inhabit these ecoregions, the nematode parasites of 32 species are known. The parasite species consisted of 51 taxa: 27 in HC and 18 in DC. The family Cosmocercidae alone included 18 species. Aplectana hylambatis and Cosmocerca podicipinus showed the widest geographical and host distribution. Leptodactylus bufonius and Rhinella major presented a high number of nematode parasites. The species richness of nematodes was related to the host body sizes and to the strategy to obtain prey. The mean species richness was higher in terrestrial amphibians with intermediate characteristics in the generalist–specialist spectrum in terms of diet, and in amphibians with intermediate characteristics between actively foraging and the “sit-and-wait” approach in terms of searching for prey. The patterns of similarity among amphibian species showed groups linking with their habitats. Nematodes usually have direct life cycles with the infectious form entering the host passively or actively. However, many amphibians are also involved in heteroxenous cycles that develop in the aquatic environment.

We collected 142 hylid frogs representing 3 species, chaco treefrog Hypsiboas raniceps, dwarf treefrog Dendropsophus nanus, and sanborn treefrog Dendropsophus sanborni, near the city of Corrientes, Corrientes Province, Argentina, between January 2002 and December 2003, and we examined them for nematodes. Two species of cosmocercid nematodes were found infecting the large intestine of these hosts. Cosmocerca parva was found infecting H. raniceps and D. sanborni, whereas Cosmocerca podicipinus was found infecting D. nanus. These nematode species are reported for the first time from these hylids from Corrientes, Argentina.
