13. Preliminary study of the presence of antibodies against excretory-secretory antigens from protoscoleces of Echinococcus granulosus in dogs with intestinal echinococcosis
The aim of the present study was to analyze the antibody response against excretory-secretory antigens (ES-Ag) from Echinococcus granulosus protoscoleces, using sera from dogs infected with E. granulosus and other helminths. ES-Ag were obtained from the first 50 h maintenance of protoscoleces in vitro. Immunochemical characterization was performed by immunob

14. Investigação sobre associação entre ácaros da poeira, atopia, manifestações alérgicas e infecções intestinais helmínticas. / Investigation beetween dust mites, atopy allergy and intestinal helminthic infections.
The role of dust mites in the determination of the clinical form of allergy has not been well established. Many records in the literature show negative association between helminth infections and allergy, however, these data are still controversial. In this study we investigated the role of B. tropicalis and D. pteronyssinus as agents of atopy and allergy an

15. Evaluation of techniques for the diagnosis of Strongyloides stercoralis in human immunodeficiency virus (HIV) positive and HIV negative individuals in the city of Itajaí, Brazil
Human immunodeficiency virus (HIV) and intestinal parasites are common in Brazil. Previous studies have shown that infection with Strongyloides stercoralis is frequently associated with HIV infection. Strongyloidiasis is difficult to diagnosis and stool examination with conventional techniques fails to detect the helminth larvae. We made a prospective study,

16. Nematode Infections Are Risk Factors for Staphylococcal Infection in Children
Nematode infection may be a risk factor for pyogenic liver abscess in children and we hypothesized that the immunomodulation induced by those parasites would be a risk factor for any staphylococcal infection in children. The present study was designed to compare, within the same hospital, the frequency of intestinal nematodes and Toxocara infection in childr

17. Toxocariase humana e parasitoses intestinais em areas sob o risco de enchentes no municipio de Campinas, Estado de São Paulo, Brasil
Human intestinal parasitoses remain a very common public health problem, and their geographical distribution and prevalence are associated with several factors, particularly the low socio-economic status of the population. Nematodes such as Toxocara canis and Toxocara cati (parasites in dogs and cats, respectively) are the main agents of the visceral and ocu

18. Plasmodium/intestinal helminth co-infections among pregnant Nigerian women
Hospital based studies were conducted to investigate the occurrence of Plasmodium/intestinal helminth co-infections among pregnant Nigerian women, and their effects on birthweights, anaemia and spleen size. From 2,104 near-term pregnant women examined, 816 (38.8%) were found to be infected with malaria parasites. Among the 816 parasitaemic subjects, 394 (48.

19. Estructura comunitaria de helmintos de perros vagabundos de San Juan de Lurigancho, Lima, Perú
Thirty stray dogs Canis familiaris Linnaeus, 1758 were collected in San Juan de Lurigancho, Lima, Peru, between January and March 1997 and necropsied for helminths. Three species were collected: the cestodes Dipylidium caninum (Linnaeus, 1758) Railliet, 1892 and Taenia pisiformis (Bloch, 1780) and the nematode Toxocara canis (Werner, 1782) Stiles, 1905. Fift

21. Human Onchocerciasis and Tetanus Vaccination: Impact on the Postvaccination Antitetanus Antibody Response
To investigate whether helminth infections may affect the efficacy of vaccines by impairing the immune response to nonparasite vaccine antigens, we compared the antibody responses to tetanus toxoid (TT) after tetanus vaccination in 193 subjects with Onchocerca volvulus infection with 85 comparable noninfected controls. After vaccination, the proportions of s

22. Infection with Toxoplasma gondii Reduces Established and Developing Th2 Responses Induced by Nippostrongylus brasiliensis Infection
Oral infection of C57BL/6 mice with 100 cysts of the protozoan parasite Toxoplasma gondii results in the development of small intestinal Th1-type immunopathology. In contrast, infection with intestinal helminths results in the development of protective Th2-type responses. We investigated whether infection with the helminth Nippostrongylus brasiliensis influe

23. Mast cells disrupt epithelial barrier function during enteric nematode infection
We have investigated the influence of mast cells on the barrier function of intestinal epithelium during nematode infection. Trichinella spiralis infection induces a strong type 2 cytokine-mediated inflammation, resulting in a critical mucosal mastocytosis that is known to mediate expulsion of the parasites from the intestine. The host response to infect

24. Peripheral Cytokine Responses to Trichuris muris Reflect Those Occurring Locally at the Site of Infection
The study of human cellular immune responses to parasite infection under field conditions is very complex. Often, the only practical site from which to sample the cellular responses is the peripheral blood. Sampling peripheral blood lymphocytes (PBL) relies on the assumption that these peripheral responses accurately reflect the immune responses acting local
