Introduction To determine the prevalence of immunoglobulin G (IgG) and M (IgM) anti-Toxoplasma gondii antibodies among pregnant postpartum women attended within public healthcare system in Niterói, State Rio de Janeiro, to detect possible exposure factors associated with T. infection this population. Methods IgM IgG anti-T. were investigated 276 124 by using indirect immunofluorescence (IFAT) immunoenzymatic assay (ELISA) techniques. The participants selected convenience sampling. All these...
The present study conducted a toxoplasmosis-related knowledge level survey with 400 pregnant and puerperal women attended in public health units the municipality of Niterói, Rio de Janeiro. Only 111 (27.8%) claimed to know about disease. Most them (n = 289; 72.2%) had never heard toxoplasmosis nor knew how prevent infection by Toxoplasma gondii. A significant difference (p 0.013) regarding presence anti-T. gondii IgG was observed between who disease those it. These results highlight...
Abstract The aim of this study was to verify the immunogenicity Pterobothrium heteracanthum (Cestoda: Trypanorhyncha) crude protein extract (PH-CPE) in BALB/c mice. parasites were obtained from Micropogonias furnieri (Osteichthyes: Sciaenidae). Groups six mice each immunized with 10, 50 or 100 μg PH-CPE, on days 0 and 35. Both specific IgG IgE responses developed after immunization. immunoblot assay revealed that recognizes PH-CPE proteins two molecular weight ranges, 60–75 30–40 kDa, larger...
Abstract The aim of this study was to determine the allergenic activity components present in crude extracts Pterobothrium crassicolle plerocerci (CPE) and blastocysts (CBE) obtained from Micropogonias furnieri a murine model. Two groups seven animals each received 50 µg CPE or CBE on days 1, 35 120. Serum samples were tested by ELISA Immunoblotting. Specific IgG IgE levels detected ELISA, showing specific humoral responses for primary immunization both immunoglobulins continuously growing...
The purpose of this study was to evaluate the contamination public squares ofthree cities located in State Rio de Janeiro, Brazil, by eggs and larvae ofhelminths, observe presence feces from animals environmentalconditions that contribute infectious structures development. Samples from60 were analyzed centrifuge-flotation spontaneoussedimentation techniques. Sixteen (26.7%) samples positive for presenceof hookworms-like eggs, 2 (3.3%) Toxocara sp; both cases fecal soilsamples analyzed....
Report of two canine dirofilariosis cases ectopic location in the state Rio de Janeiro. This is first report erratic migration for this parasitosis dogs state, calling attention to short period time between cases. The fact that area endemic parasite, its zoonotic potential and human demonstrates authorities should be alerted control programs along with pathogenic profile infections.
Abstract: Trichiurus lepturus (Actinopterygii, Perciformes) is a commercially and economically important fish. A total of 60 specimens this cutlassfish were collected the coast municipalities Niterói Cabo Frio, state Rio de Janeiro, Brazil. The fish measured, necropsied, filleted had their organs investigated for digenetic trematodes. Taxonomic identification was based on morphological morphometric characters. T. parasitized with adult Lecithochirium monticellii. Parasite indices prevalence,...
Abstract Fish consumption plays an important role in human diet. Hoplias malabaricus, commonly known as traíra, is a freshwater fish widely appreciated several Brazilian states and frequently infected by Eustrongylides sp. fourth-instar larvae (L4). The aim of the present study was to evaluate allergenic potential L4 crude extract (CEE). BALB/c mice were immunized intraperitoneally (IP) 10 μg CEE with 2 mg aluminum hydroxide on days 0 35. Specific IgG IgE antibody levels determined after...
Some fish parasites can cause a variety of symptoms in humans, including allergies. This was cross-sectional study based on interviews, serum analysis by ELISA for anti-Pterobothrium heteracanthum IgG and statistical evaluation. Four individuals were seroreactive (6.25%), with no association handling (p = 1.000) or ingestion more than twice week 0.232). There significant 0.032) between reactivity the absence allergy symptoms. Seroreactivity against P. humans detected, but not associated...
A avaliação do curso da infecção por Toxoplasma gondii em camundongos alimentados com micotoxinas, utilizando a histopatologia e imuno-histoquímica, demonstrou ocorrência de lesões mais acentuadas nos animais infectados expostos às toxinas.Diferentes quadros inflamação necrose encefálica hepática mostraram que associação entre parasitismo ingestão das micotoxinas causou agravamento nas lesões.A fumonisina B1(FB1, isolada ou associada outras micotoxinas) foi responsável alterações celulares...
The present study evaluated the frequency of intestinal parasitoses in children public day care centers applying parasitological and immunological diagnostic methods. Fecal samples from 121 six daycare were analyzed using techniques. Epidemiological data obtained through a questionnaire, where parents / or guardians asked, for instance, whether had contact with soil, ate raw food, such as vegetables undercooked meat, normally walked around barefoot animals. 82 also tested Giardia...
O desconhecimento ou nível insatisfatório de informações sobre as enteroparasitoses e sua prevenção, aliados ao baixo socioeconômico, educacional insuficiência saneamento básico, têm sido apontados como fatores risco para a aquisição dessas infecções. Neste estudo foram averiguados os conhecimentos estudantes do 3º 7º ano Ensino Fundamental dos funcionários sete escolas Municipais Niterói, RJ, Brasil. Foram aplicados questionários, respostas avaliadas adequadas, inadequadas, incompletas, não...
Inserir novos recursos na prática pedagógica é um importante aliado do processo de ensino. A utilização vídeos divulgados pela mídia busca garantir o acesso ao conhecimento diversas formas e aprimorar a dinâmica ensino no ambiente da sala aula. Este estudo buscou avaliar contribuição inclusão seriados com conteúdo parasitologia durante as aulas, como estratégia complementar Foram projetados discutidos forma crítica episódios “Dr. House” “Parasitas assassinos”. As atividades foram avaliadas...
The aim of this study was to evaluate the association between a longer sedimentation time, reading larger number slides, and collection multiple samples on efficiency spontaneous technique. Twenty-two patients with previous parasitological exam positive for intestinal protozoa were recruited collect new fecal (3 per patient) before beginning antiparasitic treatment. All collected used centrifuge-flotation techniques. Of these, all 22 based sedimentation, 59.1% (13/22) centrifuge flotation....
