Purpose This study aims to characterise the different dipteran vector communities present at a peri-urban zoological and to explore differences in community composition among the different mammalian hosts, and to assess their potential epidemiological risk. Methods Five animal enclosures were sampled and compared using CDC light traps equipped with white lights (WL) and ultraviolet traps (UV), used alternatively over five week...

Objectives This study investigated the helminth fauna of Serrasalmus maculatus and Serrasalmus marginatus in a protected area (Santa Helena Biological Refuge) and in the lower São Francisco Falso River, Brazil. The main objective was to compare the parasitic helminth fauna of these species between the areas of occurrence and to develop an updated list of the recorded parasite species. Methods Fifty individuals of each host spe...

Purpose Strongyloidiasis is an intestinal helminthiasis that can induce structural alterations in the intestinal mucosa during infection. The present study evaluated histomorphometric alterations of the small intestine in mice experimentally infected with Strongyloides venezuelensis and treated with Rosmarinus officinalis essential oil. Methods Infected animals were treated orally with R. officinalis essential oil (200 or 400...

Background The diversity of coccidians in Neotropical wild avifauna remains significantly underestimated, particularly within the family Hirundinidae. While cosmopolitan and widely distributed hosts like Hirundo rustica Linnaeus, 1758 dominate the literature with three described Isospora spp., ecological traits of other swallows may drive different parasitic dynamics. This study provides the first integrative characterization...

The present study identified an undescribed myxozoan parasite species infecting Hoplias malabaricus specimens collected from the Arari River, in the municipality of Cachoeira do Arari in the state of Pará, northern Brazil. Thirty specimens were necropsied to search for microparasite, and when plasmodium found, material was collected for analysis via light microscopy, histology and molecular biology methodologies. Macroscopic p...
