Objectives: This retrospective study was undertaken between 2008 and 2009 to assess the seroprevalence of Toxoplasmosis among pregnant women and the role of the parity, the age and the abortion presence or absence in acquisition of infection pregnant women at the National Institute of health in Rabat in Morocco. Methods: Specific T. gondii IgG and IgM were measured by Enzyme-Linked Immunosorben...

Respiratory syncytial virus (RSV) is the leading cause for respiratory illness that requires hospitalization in infancy. High levels of maternal antibodies can protect against RSV infection. However, RSV-infected infants can suffer from severe disease symptoms even in the presence of high levels of RSV-specific antibodies. This study analyzes several serological characteristics to explore poten...

abstract background: varicella is a highly contagious and dangerous disease especially in immunocompromised patients. children with cancer are at increased risk of severe illness and may fatal cases occur. vaccination from vzv ( varicella zoster vaccine) infection can be safe, immunogenic, and effective in children with leukemia who meet the criteria and are at the risk of serious disease or de...

Significant differences in both specificity and avidity of anti-DNA antibodies were observed in the sera of groups of patients with active systemic lupus erythematosus glomerulonephritis, active systemic lupus erythematosus without nephritis, and in IgG eluates obtained by DNAase digestion of isolated glomeruli from glomerulonephritic kidneys. With methylated albumin-kieselguhr fractionated 3H-...

The standardized enzyme-linked immunosorbent assay (ELISA) for measurement of serum immunoglobulin G (IgG) antibody responses to meningococcal C polysaccharide has been modified to employ assay conditions that ensure specificity and favor detection primarily of high-avidity antibodies. The modified and standard assays were used to measure IgG antibody concentrations in sera of toddlers vaccinat...

To determine quantitatively the number and avidity of receptors for the Fc portion of IgG on human platelets, we have measured the binding to platelets of human monomeric monoclonal IgG, and of small covalently crosslinked polymers of IgG1 labeled with 125I. The binding of labeled IgG1 monomers to platelets is too weak to permit quantitation. The binding of dimers or larger polymers of IgG1 is ...

OBJECTIVES We determined the seroprevalence and correlates of Toxoplasma gondii infection in pregnant women in Aguascalientes City, Mexico. DESIGN A cross-sectional survey. SETTING Pregnant women were enrolled in the central Mexican city of Aguascalientes. PARTICIPANTS We studied 338 pregnant women who attended prenatal care in 3 public health centres. PRIMARY AND SECONDARY OUTCOME MEAS...

During the 2009-2010 H1N1 influenza pandemic, an adjuvanted monovalent vaccine containing ∼25% of the normal antigen dose and AS03 adjuvant was widely used in Canada. This vaccine was found to be well-tolerated and immunogenic in young children (D. W. Scheifele et al., Pediatr. Infect. Dis. J. 30:402-407, 2011). We report here additional analyses to further characterize the humoral response to ...
