2. Seroprevalence of Toxoplasma gondii and Toxocara canis in a human rural population of Southern Rio Grande do Sul
ABSTRACT Due to the growing population of pets, especially homeless dogs and cats, zoonoses still represent a significant public health problem. Toxoplasma gondii and Toxocara spp. are epidemiologically important zoonotic agents as they are etiological factors of human toxoplasmosis and toxocariasis, respectively. These parasites remain neglected even though

3. Experimental toxocariasis in BALB/c mice: relationship between parasite inoculum and the IgG immune response
BALB/c mice were inoculated with 5-500 Toxocara canis infective eggs, and bled at 15-120 days post infection (dpi) to evaluate the dynamics of IgG antibody response and larvae distribution. Positive results were observed in all occasions for every inoculum, and a direct proportional relationship between antibody detection and the parasitic load was observed.

4. Toxocara spp. seroprevalence in pregnant women in Brasília, Brazil
Abstract INTRODUCTION: The impact of gestational toxocariasis is an understudied topic on female reproductive health. We estimated anti-Toxocara IgG prevalence among pregnant women in Brasília, Brazil, and investigated the association of the infection with history of abortion and contact with pets. METHODS: Infection was diagnosed using ELISA with excre

5. Infecção experimental de Tilápia-do-nilo (Oreochromis niloticus Linnaeus 1757) por Toxocara canis / Experimental study of migration of Toxocara canis in Nile Tilapia (Oreochromis niloticus)
A toxocaríase é uma doença de distribuição mundial, causada pelos nematódeos Toxocara canis e T. cati, parasitos cujos hospedeiros definitivos são os cães e os gatos, respectivamente. Esses agentes podem também infectar seres humanos, e suas larvas podem migrar pelo organismo, ocasionando a síndrome de larva migrans visceral (toxocaríase visceral)

6. An evaluation of the dot-ELISA procedure as a diagnostic test in an area with a high prevalence of human Toxocara canis infection
The aim of this work was to evaluate a dot-enzyme-linked immunosorbent assay (dot-ELISA) using excretory-secretory antigens from the larval stages of Toxocara canis for the diagnosis of toxocariasis. A secondary aim was to establish the optimal conditions for its use in an area with a high prevalence of human T. canis infection. The dot-ELISA test was standa

7. Detecção de larvas de toxocara canis em leite de coelhas infectadas experimentalmente / Detection of larvae of Toxocara canis in milk from experimentally infected rabbits
Com objetivo de estudar a possibilidade de transmissão de larvas pela via transmamária em coelhos, doze coelhas (Nova Zelândia) nulíparas foram infectadas com 1000 ovos larvados de T. canis, por via oral. Outras cinco coelhas receberam oralmente solução fisiológica e serviram como controle. Um mês após a inoculação, cada quatro coelhas foram acasa

8. Prevalência e fatores associados à presença de anticorpos anti-Toxocara spp. em doadores de sangue de Presidente Prudente, São Paulo. / Prevalence and associated factors with anti-Toxocara Spp. antibodies in blood Donors of Presidente Prudente, São Paulo, Brazil
A toxocaríase é uma zoonose de distribuição mundial ocasionada por Toxocara canis e T. cati, que são parasitos de cães e gatos, respectivamente. A doença é mais comum em crianças, mas pode também acometer adultos. A finalidade do presente estudo foi avaliar a soroprevalência de IGg anti-Toxocara spp. em 253 doadores de sangue entre 19 e 65 anos de

9. Evidence for eosinophil recruitment, leukotriene B4 production and mast cell hyperplasia following Toxocara canis infection in rats
It is well known that eosinophilia is a key pathogenetic component of toxocariasis. The objective of the present study was to determine if there is an association between peritoneal and blood eosinophil influx, mast cell hyperplasia and leukotriene B4 (LTB4) production after Toxocara canis infection. Oral inoculation of 56-day-old Wistar rats (N = 5-7 per gr

10. Identification of candidate antigens from adult stages of Toxocara canis for the serodiagnosis of human toxocariasis
In the present work, we identified adult Toxocara canis antigens through sodium dodecyl sulfate-polyacrylamide gel electrophoresis for potential use in human toxocariasis immunodiagnosis. The sensitivity and specificity of several semi-purified antigens, as well as their cross-reactivity with other parasitic infections, were assessed by IgM and IgG-enzime li

11. Infecção de gerbils (Meriones unguiculatus) com Toxocara canis : migração de larvas e estudo morfológico com pesquisa imunohistoquímica de antígenos de larvas nas lesões
Introduction. In last years, the gerbils have been used as experimental model of toxocariasis, especially for studies of ocular lesions and central nervous system. Objectives. To study the migration of larvae and lesions with immunohistochemical study in gerbils infected or re-infected with Toxocara canis. Methods. Gerbils were infected with 1,500 embryonate

12. Acute schistosomiasis mansoni: revisited and reconsidered
Acute schistosomiasis is a systemic hypersensitivity reaction against the migrating schistosomula and eggs. A variety of clinical manifestations appear during the migration of schistosomes in humans: cercarial dermatitis, fever, pneumonia, diarrhoea, hepatomegaly, splenomegaly, skin lesions, liver abscesses, brain tumours and myeloradiculopathy. Hypereosinop
