1. Hypogammaglobulinemia: a diagnosis that must not be overlooked
Humoral immunological defects are frequent and important causes of hypogammaglobulinemia, leading to recurrent infections, autoimmunity, allergies, and neoplasias. Usually, its onset occurs in childhood or during the second and third decades of life; however, the diagnosis is made, on average, 6 to 7 years afterwards. As a consequence, antibody defects can l

2. Neuromielite óptica recorrente - aspectos clínicos, imunológicos e imagenológicos / Recurrent neuromyelitis optica in brazilian patients: clinical, immunological, and neuroimaging characteristics
INTRODUÇÃO: A neuromielite óptica (NMO) recorrente não foi completamente estudada em pacientes brasileiros após a descoberta do autoanticorpo sérico NMO-IgG e seu antígeno específico aquaporina-4. Neste trabalho, descrevemos os aspectos clínicos, imunológicos e de ressonância magnética (RM) de pacientes portadores de NMO recorrente. MÉTODOS: For

3. Estudo da flutuação sérica de anticorpos maternos nos períodos pré e pós-parto e transferência de imunidade passiva em cabritos recém-nascidos utilizando colostro bovino e caprino / Study of maternal serum antibodies fluctuation in pre and post partum period and passive immunity transfer in newborn goat kids using bovine and caprine colostrum
The objective of this study was to evaluate the fluctuation of serum antibodies in goats pre and immediately post partum period and the passive immunity acquisition efficiency in goat kids fed caprine and bovine colostrum, contributing for an evaluation of colostrum management alternative and a better knowledge of passive immunity formation and transference

4. Proteção imunológica contra a formação de cistos cerebrais em camundongos vacinados pela via nasal com proteínas recombinates de Toxoplasma gondii
Toxoplasma gondii is a protozoan parasite which can invade and reside in a wide range of host cells. It can infect all warm-blooded animals, including human being. Parasite invasion is associated with protein secretion from three organelles: micronemes, rhoptries and dense granules. These excreted/secreted antigens were highly immunogenic in humans and roden

5. Immunoglobulin in the pathogenesis in visceral leishmaniasis in hamsters / "Imunoglobulina na patogenia da leishmaniose visceral em hamsteres"
Pathogenesis of tissue lesions in visceral leishmaniasis (VL) was searched in hamsters infected with Leishmania (Leishmania) chagasi amastigotes. Internalization of IgG from VL hamsters by human umbilical vein endothelial cells was observed in vitro and in liver and kidney in hamsters VL, under transmission electron microscopy, at 30 and 60 days of infection

6. "Resposta imune humoral na malária humana: quantidade e qualidade de anticorpos anti-Plasmodium falciparum" / Humoral immune response in human malaria : quantity and quality of anti-Plasmodium falciparum antibodies
Neste estudo avaliamos a resposta imune humoral de indivíduos naturalmente expostos à malária em áreas endêmicas no Brasil. Os anticorpos IgG, IgG1, IgG2, IgG3, IgG4, IgM, IgE e IgA anti-formas eritrocitárias de Plasmodium falciparum foram determinadas por ELISA. Anticorpos IgG, IgG1, IgG2 de alta avidez e IgG3 de baixa avidez predominaram nos indivíd

7. Avaliação do BCG como adjuvante na imunoterapia específica para asmáticos / Assessment of BGC as an adjuvant in specific immunotherapy in asthmatic patients
O aumento da prevalência de doenças alérgicas como a asma, tem sido atribuído à falta de estímulos infecciosos. A atopia, que embasa as manifestações alérgicas, caracteriza-se por uma disfunção imune com predomínio da resposta do tipo Th2. Experimentos em modelos animais com micobactérias e seus produtos têm demonstrado resultados promissores n

8. Assessment of laboratory improvement by the Center for Disease Control Diagnostic Immunology Proficiency Testing Program.
The data accumulated from 1969 to 1979 in the Diagnostic Immunology portion of the Center for Disease Control Proficiency Testing Program were evaluated for evidence of change in performance among the participating laboratories. Evidence of improved performance was found for the rubella, rheumatoid factor, tularemia, quantitative immunoglobulin (immunoglobul

9. Immunology of the monobactam aztreonam.
To assess the immunological cross-reactivity of the monobactam antibiotic aztreonam (AZ), rabbits were immunized with protein conjugates of benzylpenicillin, cephalothin (CEPH), and AZ. The resulting antibenzylpenicilloyl (BPO) and anti-CEPH rabbit antibodies showed negligible cross-reactivity with AZ conjugated to human serum albumin (AZ-HSA), whereas anti-

10. Antibodies against papillomavirus antigens in cervical secretions from condyloma patients.
Samples of cervical secretions and serum from 30 women with genital condylomas and 30 age-matched controls were tested for the presence of immunoglobulin A (IgA) and IgG antibodies against a panel of papillomavirus-derived antigens. The same cervical samples were also analyzed for presence of human papillomavirus (HPV) DNA by Southern blotting and polymerase

11. Early and early disseminated phases of Lyme disease in the rhesus monkey: a model for infection in humans.
We demonstrate that Borrelia burgdorferi infection in the rhesus monkey mimics the early and early disseminated phases of human Lyme disease. Clinical, bacteriological, immunological, and pathological signs of infection were investigated during 13 weeks after inoculation of the spirochete. Three animals were given B. burgdorferi (strain JD1) by needle inocul

12. Evaluation of Rapid Diagnostic Tests for Typhoid Fever
Laboratory diagnosis of typhoid fever requires isolation and identification of Salmonella enterica serotype Typhi. In many areas where this disease is endemic, laboratory capability is limited. Recent advances in molecular immunology have led to the identification of sensitive and specific markers for typhoid fever and technology to manufacture practical and
