Ectoparasites of Nile tilapia (Oreochromis niloticus) in cage farming in a hydroelectric reservoir in Brazil.
TLDR
For the majority of ectoparasites found in this study, fish in the intermediate and final phases had higher parasitism rates than those in the initial phase, which may help fish farmers to understand the parasite dynamics of the fish species studied in cage-farming systems.
Parasitism by Sphincterodiplostomum musculosum (Digenea, Diplostomidae) metacercariae in the eyes of Steindachnerina insculpta (Characiformes, Curimatidae).
TLDR
The histological analyses revealed that the metacercariae were apparently lodged behind the retina, and this pattern can be explained by the cumulative effect of parasitism, as demonstrated by the positive correlation between the abundance of metacertariae and fish body size.
The Relationships between Parasite Intensity, Locomotor Performance, and Body Condition in Adult Toads (Rhinella icterica) from the Wild
TLDR
Individuals with higher parasite intensity did not show poorer body condition or higher standard metabolic rates, suggesting that parasite intensity in the field was not associated with large changes in energy stores and that the relationship between parasite intensity and host performance remains nonsignificant during conditions of low energy demand.
Parasitic communities of Hoplosternum littorale (Hancock, 1828) as indicators of environmental impact.
TLDR
The results of the physicochemical analysis of the water showed that the mouth of the Peixe River can be considered an area that suffers more from anthropogenic actions than the Lagoa da Cabeça de Boi.
Chapiniella variabilis (Nematoda) parasitizing Chelonoidis carbonarius and C. denticulatus (Testudinidae) in the state of Piauí.
TLDR
The present study adds new observations on the morphology, mainly relating to the mouth papillae, external and internal leaf-crown elements, excretory pore, deirids and male and female posterior end to the Chapiniella variabilis, to the Neotropical region of South America.
First case of an infection of the metacercariae of Austrodiplostomum compactum (Lutz, 1928) (Digenea, Diplostomidae) in Hypostomus regani (Ihering, 1905) (Siluriformes: Loricariidae)
TLDR
This is the first report of a loricarid fish infected with A. compactum, which was recorded infecting the eyes of a Hypostomus regani.
Prevalence and distribution of Angiostrongylus cantonensis (Nematoda, Angiostrongylidae) in Achatina fulica (Mollusca, Gastropoda) in Baixada Santista, São Paulo, Brazil.
TLDR
This study aimed to determine the prevalence of A. cantonensis infection in Achatina fulica in the nine municipalities that make up Baixada Santista, São Paulo, Brazil.
Helminth fauna of Leptodactylus syphax (Anura: Leptodactylidae) from Caatinga biome, northeastern Brazil.
TLDR
New helminth records for the Neotropical region are presented, thus helping in understanding the pattern of species distribution, and it increases the knowledge of parasites associated with amphibians.
Hemoparasites of the genus Trypanosoma (Kinetoplastida: Trypanosomatidae) and hemogregarines in Anurans of the São Paulo and Mato Grosso do Sul States - Brazil.
TLDR
The objective of the present study was to evaluate the presence of hemogregarines and Trypanosoma spp.
A new species of Tereancistrum (Monogenea, Dactylogyridae) from the gills of three Leporinus species (Characiformes, Anostomidae) and a revised description of Tereancistrum parvus.
TLDR
This new species is mainly characterized by the morphology of the copulatory complex, a dorsal anchor with a well-developed superficial and inconspicuous deep root, and the shape of the accessory anchor sclerite with small spathulate termination.
