Crassicaudiasis in three geographically and chronologically distant Cuvier's beaked whales () stranded off Brazil.

The Cuvier's beaked whale (CBW; ) is a cosmopolitan marine mammal found in deep tropical and temperate waters of all oceans. CBW strandings have been recorded sporadically in Brazil; however, there is lack of information available regarding their causes of stranding and/or death. Herein, we report the epidemiologic, pathologic, morphologic parasitologic features and molecular identification of arterial and renal crassicaudiasis by sp.

Endoparasites observed within invertebrates used as live food items for captive wild birds: Overview and potential risks.

To monitor and evaluate potential risks to birds' health, invertebrate species that have been used as live food items had their body contents searched for endoparasites. The contents of approximately 10,000 invertebrates were analyzed. A principal component analysis was performed to study the relationship between the presence/absence of endoparasites and the characteristics of the invertebrates.

POTENTIAL CROSS-CONTAMINATION OF SIMILAR Giardia duodenalis ASSEMBLAGE IN CHILDREN AND PET DOGS IN SOUTHERN BRAZIL, AS DETERMINED BY PCR-RFLP.

Giardia duodenalis is an enteric parasite that has distinct genetic groups. Human infections are mainly caused by assemblages A and B, although sporadic infections by assemblages C and D have also been reported. Animals can be infected by a wide range of assemblages (A to H).

The use of epifluorescence microscopy and fluorescent dyes for visualization of Oxyuris equi eggs.

This study presents a new method for visualization of Oxyuris equi eggs collected by means of a clear adhesive tape applied to the perianal region of horses. The obtained results indicate that this protocol permits a quick, easy, clear and selective visualization of Oxyuris equi eggs even in the presence of feces and other material. Another advantage of this method is that it can be used with fluorescent dyes solubilized in water, which will stain biologic material without dissolving or altering the adhesive tape and is also environmentally safe.

Toxoplasma gondii seropositivity and risk factors in pregnant women followed up by the Family Health Strategy.

Introduction: Toxoplasmosis is a zoonotic infection caused by Toxoplasma gondii. It is transmitted by the ingestion of contaminated water and foods, by soil contaminated with cat feces, especially while handling it, and congenitally via the placenta. The diagnosis of maternal infection is made by serological detection of either IgM or IgG antibodies.

Capillaria hepatica in Puma concolor: first report in Brazil.

Capillaria hepatica was detected by histopathologic diagnosis in two cougars that were shot in April 2008 in Painel, Santa Catarina, Brazil. Macroscopic analysis of their livers revealed the presence of diffuse granulomas, and the histopathologic analysis indicated the presence of C. hepatica eggs, surrounded by mononuclear inflammatory cell infiltrate, small foci of necrosis, and mild-to-moderate fibrosis.

Presence of Fasciola hepatica in feral nutria (Myocastor coypus) living in a public park in Brazil.

Sixteen nutria (Myocastor coypus) from a protected area in Curitiba, Brazil, were sampled to determine the prevalence of Fasciola hepatica eggs and intestinal parasites and the presence of snails in the habitat used by nutria. The overall prevalence rates were 56.25% (9) for F.

Glomerulonephritis in water buffaloes (Bubalus bubalis) naturally infected by Fasciola hepatica.

Glomerulonephritis caused by Fasciola hepatica was observed in buffaloes. Renal biopsies of 20 buffaloes, 11 with F. hepatica and 9 uninfected buffaloes (controls), were examined by light microscopy, direct and indirect immunofluorescence, and immunohistochemical analysis.
