25. Enzyme-linked immunosorbent assay and Western blot antibody determination in sera from patients diagnosed with different helminthic infections with Anisakis simplex antigen purified by affinity chromatography
An evaluation of the sensitivity and the specificity of the Anisakis simplex antigens purified by affinity chromatography was performed using sera from patients diagnosed with Anisakis sensitisation and sera from patients previously diagnosed with different helminthic infections. Only the sera of the patients diagnosed with Schistosoma mansoni or Onchocerca

26. Helmintos e protozoários em fezes de javalis (Sus scrofa scrofa) criados em cativeiro
Faecal samples from 79 wild boars (Sus scrofa scrofa) were examined by sedimentation method, zinc sulfate flotation method, and centrifugal flotation in sugar solution for endoparasites research. The results showed that 97.5% of the samples were positive for helminths and/or protozoa as follows: strongilides (70.9%), Ascaris suum (46.9%), Trichuris suis (29.

27. Comparison of different monoclonal antibodies against immunosuppressive proteins of Ascaris suum
The extract of Ascaris suum suppresses the humoral and cellular immune responses to unrelated antigens in the mouse. In order to further characterize the suppressive components of A. suum, we produced specific monoclonal antibodies which can provide an important tool for the identification of these proteins. The A. suum immunosuppressive fractions isolated b

28. Freqüência de soropositividade para antígenos de Toxocara canis em crianças de classes sociais diferentes
Para estudar a freqüência da infecção pelo Toxocara canis em crianças de classes sociais diferentes de Brasília, Brasil, foram testados soros de 602 crianças de ambos os sexos, de 1 a 12 anos, distribuídas em dois grupos representativos de condições socioeconômicas distintas. As amostras do primeiro grupo foram obtidas em laboratório público que

29. Evolution of ascariasis in humans and pigs: a multi-disciplinary approach
The nematode parasite Ascaris lumbricoides infects the digestive tracts of over 1.4 billion people worldwide, and its sister species, Ascaris suum, has infected a countless number of domesticated and feral pigs. It is generally thought that the putative ancestor to these worms infected either humans or pigs, but with the advent of domestication, they had amp

30. Characterization of Sm14 related components in different helminths by sodium dodecyl sulphate-polyacrylamide gel electrophoresis and Western blotting analysis
Sm14 was the first fatty acid-binding protein homologue identified in helminths. Thereafter, members of the same family were identified in several helminth species, with high aminoacid sequence homology between them. In addition, immune crossprotection was also reported against Fasciola hepatica infection, in animals previously immunized with the Schistosoma

31. Evaluation by ELISA of Anisakis simplex Larval Antigen Purified by Affinity Chromatography
In order to improve the specificity and sensitivity of the techniques for the human anisakidosis diagnosis, a method of affinity chromatography for the purification of species-specific antigens from Anisakis simplex third-stage larvae (L3) has been developed. New Zealand rabbits were immunized with A. simplex or Ascaris suum antigens or inoculated with Toxoc

32. Extracts of Ascaris suum egg and adult worm share similar immunosuppressive properties
Adult Ascaris suum body extract (Asc) prepared from male and female worms (with stored eggs) down-regulates the specific immune response of DBA/2 mice to ovalbumin (OA) and preferentially stimulates a Th2 response to its own components, which is responsible for the suppression of the OA-specific Th1 response. Here, we investigated the participation of solubl

33. Production and characterization of a monoclonal antibody against an Ascaris suum allergenic component
Ascaris suum allergenic components (PIII) separated by gel filtration chromatography of an adult worm extract were used to immunize BALB/c mice. Popliteal lymph node cells taken from the immunized animals were fused with SP2/O myeloma cells using polyethylene glycol (MW 1450) as fusogen. The hybridomas were cultured in HAT-containing medium and cloned at lim

34. Ocorrência de helmintoses, de suínos criados na periferia de Itabuna - Bahia
O presente trabalho relata os resultados obtidos a partir de um levantamento helmintológico, com ênfase especial para cisticercose, em 50 suínos (29 fêmeas e 21 machos), sem raça definida, com idade de quatro a 18 meses, peso corporal entre 15 a 70Kg, precedentes de criações da periferia do município de Itabuna, Bahia. A necropsias, a identificação

35. Propriedades imunorreguladoras de extratos solúveis obtidos de vermes adultos ou de ovos de Ascaris suum. / Immunoregulatory properties of soluble extracts from Ascaris suum worms or eggs.
O extrato de Ascaris suum (Asc total), preparado a partir de uma mistura de vermes machos e fêmeas (albergando ovos), suprime a resposta imune específica a ovalbumina (OA). A partir do fracionamento deste extrato por gel filtração demonstrou-se que componentes protéicos de alto peso molecular (PM), eluídos no primeiro pico (PI), eram supressores da res

36. Humoral factors affecting mouse peritoneal cell adherence reactions to Ascaris suum.
The abilities of normal mouse peritoneal exudate cells and fluids to mediate in vitro cell adherence reactions to Ascaris suum juveniles were investigated. Exudates were induced by intraperitoneal injection of Sephadex G-25 or by infection with A. suum and changes in the peritoneal cell populations were determined. The presence of a heat-labile component, pr
