An anisakid nematode larva found in cod sold in the state of Minas Gerais, Brazil was studied by light and scanning electron microscopy and by a molecular approach. Mitochondrial cytochrome c-oxidase subunit 2 (mtDNA cox-2), 28S rRNA and ITS1, 5.8S and ITS2 regions were amplified using the polymerase cha...

A total of 103 specimens of Hoplias intermedius (Günther, 1864) and 86 specimens of H. malabaricus (Bloch, 1794) from the upper São Francisco River, State of Minas Gerais were collected between April 2011 and August 2013, and their parasitic fauna were investigated. Four species of Digenea were found: ...
In this study, an important ornamental fish, Betta splendens (Osphronemidae), from three different Brazilian states was examined for parasitic infestations. Smears with parasites were impregnated with silver nitrate or stained using Giemsa for taxonomic evaluation. A disc-shaped trichodinid with a body d...
This paper describes the morphology of Cucullanus pinnai pinnai parasitizing Pimelodus maculatus in the Guandu River, Brazil, based on differential interference contrast (DIC) microscopy and scanning electron microscopy (SEM), providing new morphological data about this species of parasite. Nematodes wer...
Neosporosis is a disease caused by the protozoon Neospora caninum that leads to significant economic losses in many countries. In the present study, we report on use of the recombinant protein NcSRS2 of N. caninum expressed in Pichia pastoris in an indirect immunoenzymatic assay (ELISA) for diagnosing ne...

This study compared the parasite communities of Hoplias malabaricus and Hoplerythrinus unitaeniatus from Amazon river system. Hoplias malabaricus were infected by Ichthyophthirius multifiliis, Piscinoodinium pillulare, Tetrahymena sp., Urocleidoides eremitus, Braga patagonica, metacercariae of Clinostomu...
The degree of parasite aggregation is determined by a number of factors that are not well understood. In total, 3,746 fish from 73 species and their parasites were analyzed to determine associations between the degree of aggregation by taxon and specific characteristics of the fish. A multiple linear reg...
O objetivo do presente estudo foi avaliar a influência do parasitismo intestinal crônico sobre parâmetros hematológicos e de líquido peritoneal por meio da comparação dessas características em equinos naturalmente parasitados e após administração de anti-helmíntico. Utilizaram-se 21 cavalos d...
Objetivo. Identificar la presencia de parásitos con potencial zoonótico en los principales parques de la ciudad de Tunja, Boyacá, Colombia. Material y métodos. Se seleccionaron 28 parques de la ciudad en los que se recogieron 124 muestras de materia fecal de perros y muestras de suelo con ayuda de un...

Nos últimos anos, grandes perdas de colônias de abelhas melíferas vêm sendo registradas em várias regiões do mundo. Contudo, os motivos desse acontecimento permanecem obscuros. O ácaro ectoparasita Varroa destructor Anderson e Trueman (Acari: Varroidae) pode ser um dos responsáveis por esse fato,...
