Taenia crassiceps injection into the subarachnoid space of rats simulates radiological and morphological features of racemose neurocysticercosis.

Purpose: Neurocysticercosis is a major public health concern. Although its eradication appears feasible, the disease remains endemic in developing countries and has emerged again in Europe and in the USA. Basic studies on neurocysticercosis are needed to better understand the pathophysiologic mechanisms and, consequently, to improve treatment perspectives.

Sinuolinea niloticus n. sp., a myxozoan parasite that causes disease in Nile tilapia (Oreochromis niloticus).

Sinuolinea species are myxozoans of the order Bivalvulida, suborder Variisporina, and family Sinuolineidae, which can be parasites for freshwater and marine fish. The aim of this study was to describe the occurrence of Sinuolinea niloticus n. sp.

Development of an experimental model of neurocysticercosis-induced hydrocephalus. Pilot study.

Purpose: To develop an experimental model of neurocysticercosis-induced hydrocephalus

Methods: There were used 17 rats. Ten animals were inoculated with Taenia crassiceps cysts into the subarachnoid. Five animals were injected with 0.

Usefulness of serological ELISA assay for Taenia saginata to detect naturally infected bovines.

Bovine cysticercosis, a cosmopolitan disease caused by Taenia saginata, leads to economic losses due to carcass devaluation at slaughter. Sanitary inspection at slaughterhouses, the routine diagnostic method in Brazil, lacks the necessary sensitivity to detect the mildly infected cattle that are typically encoutered in Brazil. In this study we have tested cattle sera from animals diagnosed as positive and negative by veterianry inspection for (1) anti-parasite antibodies using metacestodes antigens (T.

Mercury concentrations in South Atlantic swordfish, Xiphias gladius, caught off the coast of Brazil.

This study evaluated the concentrations of mercury in fillets (anterior, middle, and end regions) from the swordfish, Xiphias gladius, and the relationships between mercury concentration and fish weight, as well as the region of collection. Of a total of 697 swordfish analyzed, 11 had mercury concentrations above 1 mg/kg, 421 were between 0.5 and 1.

Ethnoveterinary knowledge and practices at Colares Island, Pará state, eastern Amazon, Brazil.

Ethnopharmacological Relevance: The lack of ethnoveterinary surveys in Brazil, especially in the Amazon region, results in losses in the veterinary phytopharmacology field and in scientific documentation of the cultural traditions of plant use in the treatment of animal diseases.

Aim Of The Study: To catalog, analyze and disseminate the ethnoveterinary knowledge of the inhabitants of Colares Island, Pará state, eastern Amazon, Brazil.

Materials And Methods: A total of 72 interviews were conducted, and semi-structured questionnaires were answered by 18 men and 54 women.

Animal cysticercosis in indigenous Brazilian villages.

Sanitary inspection of beef and pork meat has been the major tool for diagnosing animal cysticercosis and for preventing taeniasis in Brazil. The indigenous villages Jaguapiru and Bororo are located close to the urban area of the municipality of Dourados in the State of Mato Grosso do Sul, Brazil, where precarious basic sanitation conditions are observed. Both cattle and pigs are raised for self-consumption of meat and milk as well as for sale on the external market, generally without official sanitary inspection.

Characterization of S3Pvac anti-cysticercosis vaccine components: implications for the development of an anti-cestodiasis vaccine.

Background: Cysticercosis and hydatidosis seriously affect human health and are responsible for considerable economic loss in animal husbandry in non-developed and developed countries. S3Pvac and EG95 are the only field trial-tested vaccine candidates against cysticercosis and hydatidosis, respectively. S3Pvac is composed of three peptides (KETc1, GK1 and KETc12), originally identified in a Taenia crassiceps cDNA library.

Taenia saginata: production and characterization of monoclonal antibodies against Taenia saginata metacestode antigens.

Cysticercosis is a major cause of economic loss in bovine production due to meat condemnation. Chemotherapy is being used in Brazilian cattle and a diagnostic test to improve the treatment program is desired. We produced monoclonal antibodies against crude (TAEB) and cyst fluid (TAEF) Taenia saginata metacestode antigens using immunized BALB/c mice.

Use of the paired samples (cerebrospinal fluid and serum) in immunodiagnostic of active and inactive human neurocysticercosis.

Paired samples of cerebrospinal fluid (CSF) and serum of 30 patients--10 with active, 10 with inactive neurocysticercosis (NCC), and 10 control subjects--were evaluated by enzyme-linked immunosorbent assay (ELISA) using two Taenia crassiceps metacestode extracts as antigen in order to detect IgG antibodies. In active NCC, high levels of IgG were detected (p < 0.05).

Application of synthetic peptides to the diagnosis of neurocysticercosis.

We tested the possible diagnostic utility of five Taenia saginata oncosphere-derived synthetic peptides in T. solium neurocysticercosis (NC). The five peptides correspond to protein sequences with high antigenic indexes that were cloned from a T.
