1. Os anticorpos produzidos pela vacina contra a COVID-19 são passados ao lactente através do leite materno?
Sim. Estudos evidenciam a presença de anticorpos no leite materno após a vacinação contra Covid-19
. Existem outros estudos que mostram a presença de IgA (anticorpo) contra a Covid-19 em leite materno após a infecção materna pelo vírus
. Porém, é importante destacar que os cuidados individuais devem ser mantidos, como evitar aglomer

2. β-Glucan of Candida albicans Cell Wall Extract Inhibits Salmonella Typhimurium Colonization by Potentiating Cellular Immunity (CD8 + and CD4 + T Cells)
Abstract INTRODUCTION: Antimicrobial resistance has been reported in the drugs used for the treatment of typhoid fever. The immunomodulatory substance β-glucan can be used as an alternative therapy as it potentiates host immunity. The aims of this study are to observe the effect of Candida albicans cell wall (CCW) extract towards host immunity (TCD8+ and T

3. The effect of swimming on oral health status: competitive versus non-competitive athletes
ABSTRACT Young swimmers are particularly susceptible to the onset of oral diseases. Objective To evaluate the oral health status in young competitive and non-competitive swimmers, involving an assessment of salivary cariogenic bacteria and secretory IgA (S-IgA) concentration. Material and Methods Before training sessions (T1), 54 competitive and 69 non-c

4. Influence of consumption of probiotics on presence of enterobacteria in the oral cavity
Clinical benefits of probiotics have been clearly reported in different gastrointestinal disorders, many of them caused by enterobacteria. The oral cavity is a port of entry and can be an important reservoir of these microorganisms. This work evaluated whether consumption of probiotics was able to influence the presence of enterobacteria in the oral cavity a

5. Ocular toxoplasmosis: evaluation of lacrimal - specific secretory IgA levels in both patients with active and inactive phases of the disease
Ocular toxoplasmosis can result in recurrent uveitis. Studies have shown that a correlation between active ocular toxoplasmosis and the presence of anti-Toxoplasma gondii secretory IgA (SIgA) in tears. This study compares anti-T. gondii SIgA levels in patients' tears during the acute and inactive phases of toxoplasmic uveitis. Twenty-nine positive tear speci

6. Reduction of the amount of intestinal secretory IgA in fulminant hepatic failure
Intestinal barrier dysfunction plays an important role in spontaneous bacterial peritonitis. In the present study, changes in the intestinal barrier with regard to levels of secretory immunoglobulin A (SIgA) and its components were studied in fulminant hepatic failure (FHF). Immunohistochemistry and double immunofluorescent staining were used to detect intes

7. Effect of hyperoxia on the intestinal IgA secretory component in neonatal rats and on intestinal epithelial cells in vitro
Oxygen therapy is essential for the treatment of some neonatal critical care conditions but its extrapulmonary effects have not been adequately investigated. We therefore studied the effects of various oxygen concentrations on intestinal epithelial cell function. In order to assess the effects of hyperoxia on the intestinal immunological barrier, we studied

8. O efeito do estresse psicológico na imunidade salivar secretória
Objetivo: estudar os níveis salivares de Imunoglobulina A Secretória (S-IgA), Imunoglobulina A1 Secretória (S-IgA1), Imunoglobulina A2 Secretória (S-IgA2) e Componente Secretor (SC), assim como as razões S-IgA/SC, S-IgA1/SC e S-IgA2/SC em estudantes universitários, incluindo um grupo apresentou sintomas depressivos, bem como estresse psicológico prolo

9. Passive acquisition of protective antibodies reactive with Bordetella pertussis by the newborn via placental transfer and breastfeeding / Aquisição passiva de anticorpos protetores reativos com Bordetella pertussis pelo recém-nascido via transferência placentária e aleitamento materno
Pertussis is currently considered an important public health problem in developed countries. Although there is no evidence of an increase in the number of pertussis cases in our country, can not rule out the hypothesis of a future re-emergence of disease, as epidemiological data from some regions show an increase in incidence, indicating that probably there

10. Prevalência de infecções urogenitais durante o trabalho de parto a termo e pré termo e associação com níveis de IgA secretora no colostro / Prevalence of urogenital infections during term and preterm labor and association with secretory IgA levels in colostrums
As infecções urogenitais (IUG) são muito prevalentes durante a gestação e são reconhecidamente uma das principais causa de trabalho de parto prematuro. Entretanto, a prevalência de IUG no período intraparto é pouco conhecida. Diversas variáveis podem alterar a concentração das imunoglobulinas no colostro. A prematuridade e as infecções urogenit

11. Influence of probiotics on Candida presence and IgA anti-Candida in the oral cavity
Probiotics are defined as microorganisms that promote benefits to host health, mainly by regulating resident microbiota. Disequilibrium in microbiota can favor the growth of opportunist microorganisms and the development of pathologies, like candidosis caused by yeasts of the Candida genus. This work evaluated whether probiotics consumption was able to influ

12. Anti-Toxoplasma gondii secretory IgA in tears of patients with ocular toxoplasmosis: immunodiagnostic validation by ELISA
Toxoplasma gondii causes posterior uveitis and the specific diagnosis is based on clinical criteria. The presence of anti-T. gondii secretory IgA (sIgA) antibodies in patients' tears has been reported and an association was found between ocular toxoplasmosis and the anti-T. gondii sIgA isotype in Brazilian patients. The purpose of this study was to provide a
