Checklist of Helminth parasites of Amphibians from South America.
TLDR
The biodiversity of helminth parasites in South American amphibians is documented to identify gaps in the authors' knowledge, which in turn may guide subsequent studies.
Helminth community structure of 13 species of anurans from Atlantic rainforest remnants, Brazil
TLDR
The data indicate that, in sympatric species of amphibians, the morphological and behavioural characteristics of the hosts are important for structuring the helminth parasite communities.
Parasitic infections of Piaractus mesopotamicus and hybrid (P. mesopotamicus x Piaractus brachypomus) cultured in Brazil.
TLDR
Assessment of parasitic infections in the "pacu" fish and the "patinga" hybrid in the northwest of São Paulo State, Brazil found that appropriate fish handling, in conjunction with monitoring of water quality, can reduce the stress to which the farmed fish are exposed and is essential for pathogen control.
How Many Parasites Species a Frog Might Have? Determinants of Parasite Diversity in South American Anurans
TLDR
It is concluded that specialist parasites are more likely to be associated with large anurans, which are the ones harbouring higher PSR, and that the lack of association of PSR with hosts’ clade diversification suggests it is strongly influenced by ecological and contemporary constrains.
Description of three new species of Hepatozoon (Apicomplexa, Hepatozoidae) from Rattlesnakes (Crotalus durissus terrificus) based on molecular, morphometric and morphologic characters.
TLDR
This is the first description of new Hepatozoon species from snakes, based on molecular characterization and morphological data, in South America, and based on the molecular and morphologic differences, three new species were proposed.
New host records and a checklist of fishes infected with Austrodiplostomum compactum (Digenea: Diplostomidae) in Brazil.
TLDR
It is hypothesized that the metacercariae larval stage of the parasite has a low specificity for the second intermediate host (fish) and the majority of fish species infected in Brazil belong to the Loricariidae and Cichlidae families.
Helminths of Lizards (Reptilia: Squamata) from Mato Grosso State, Brazil
TLDR
Eleven new host records and 10 new state (1 new country) records were reported.
Antitumor effect of Bothrops jararaca venom.
TLDR
It was observed that in vivo treatment with BjV induced tumor growth inhibition, increased animal survival time, decreased mortality, increased the influx of polymorphonuclear leukocytes on the early stages of tumor growth, and did not affect the mononuclear cells number.
Diversity in the genus Rhabdias (Nematoda, Rhabdiasidae): Evidence for cryptic speciation
TLDR
Results suggest evidence for host–parasite cophylogeny in the R. pseudosphaerocephala complex and dispersal events among their populations, and supported the monophyly of Rhabdiasidae and improved the resolution of main clades.
Morphological and Molecular Characterization of Clinostomum detruncatum (Trematoda: Clinostomidae) Metacercariae Infecting Synbranchus marmoratus
TLDR
Both neighbor-joining (NJ) and maximum likelihood (ML) trees showed 2 clear separate clusters grouping together the species from the Palearctic region and those from the Nearctic/Neotropical regions.
