Isopods Cymothoidae ectoparasites of fish from the Amazon

Abstract Most freshwater species of Cymothoidae are distributed in South America. They have mainly been recorded in the eastern and western regions of the Amazon River basin. However, in this ecosystem, the biodiversity of this group may be greater if the entire Amazon basin is considered. In this regard...

Gastrointestinal and external parasites of the Variable hawk Geranoaetus polyosoma (Accipitriformes: Accipitridae) in Chile

Abstract Information about parasites associated with diurnal raptors from Chile is scarce. Between 2006 and 2017, a total of 15 specimens of the Variable hawk, Geranoaetus polyosoma (Quoy & Gaimard, 1824) were collected, 14 of them from different localities in the Biobío region and one specimen from...

External and intestinal parasites of the Austral thrush Turdus falcklandii (Aves, Turdidae) in central Chile

Abstract A total of thirty Austral thrushes Turdus falcklandii Quoy & Gaimard, 1824 (Turdidae) carcasses were brought to the Departamento de Ciencia Animal, Facultad de Ciencias Veterinarias, Universidad de Concepción, to be examined for ecto- and endoparasites. Ectoparasites were found on 20% (6/30...

Occurrences of Ornithocoris toledoi (Cimicidae) on a free-range chicken farm in the state of Rio de Janeiro, Brazil

Abstract Ornithocoris toledoi is a hematophagous insect that parasites birds, particularly, galliformes. Although the occurrence of this arthropod is relatively low in Brazil, this is an important ectoparasite associated with backyarding poultry. The objective of this study was to report the occurrence o...

Gastrointestinal and ectoparasites of plumbeous rail, Pardirallus sanguinolentus (Aves: Rallidae) in Central Chile

Abstract With the aim to identify the parasite fauna of plumbeous rail, Pardirallus sanguinolentus (Aves: Rallidae) in Chile, 26 carcasses were parasitologically necropsied. The present study revealed the presence of 14 species of parasites (inverse Simpson index = 4.64; evenness = 0.332), including ect...

Domestic infestation by Sclerodermus sp. with associated skin manifestation

An. bras. dermatol; 93 (4), 2018
Abstract: Sclerodermus sp. is an aculeate insect (Hymenoptera: Bethylidae), measuring 2-4 mm in length. It is a parasitoid and needs termites as hosts to complete its life cycle. It is found in a wide variety of woods and may accidentally sting humans who come near affected wooden objects. A 50-year-old ...

External and gastrointestinal parasites of the rufous-collared sparrow Zonotrichia capensis (Passeriformes, Emberizidae) in Chile

Abstract A total of 277 rufous-collared sparrows, Zonotrichia capensis Müller, 1776 (Emberizidae), were examined for external parasites. The birds were captured using mist nets in seven locations in northern and central Chile. Additionally, seven carcasses from central Chile (the Biobío region) were ne...

Parasites of the Southern silvery grebe Podiceps occipitalis (Aves, Podicipedidae) in Chile

Abstract A total of 97 southern silvery grebes (Podiceps occipitalis), which died as the result of an oil spill on the coast of central Chile, were examined for ecto- and endoparasites. Two lice species including Aquanirmus rollandii (Philopteridae) and Pseudomenopon dolium (Menoponidae) were found from ...

Does hair coat length affect flea infestation in naturally infested dogs?

Abstract The Siphonaptera are parasitic insects of endothermic animals and Ctenocephalides felis and Pulex irritans are important parasites of dogs. This study evaluated the effect of hair coat length and time of year on the population size of C. felis and P. irritans in naturally infested dogs. Fleas we...

Gastrointestinal and external parasites of Enicognathus ferrugineus and Enicognathus leptorhynchus (Aves, Psittacidae) in Chile

Abstract Parasite species are important components of biodiversity, as they provide valuable information about host health, evolutionary relationships, population structures, trophic interactions, the existence of environmental stresses, and climatic conditions. With the aim of describing the parasites a...
