The epidemiology of vaccine preventable virus infections : studies of rubella virus and hepatitis B virus infections performed by oral fluid testingVyse, Andrew J. January 2000 (has links)
This thesis presents studies on the epidemiology of vaccine preventable VIruS infections investigated by oral fluid testing. It involved studies of both rubella and hepatitis B virus infections by the detection of specific IgG in oral fluid and of rubella virus by PCR detection and genotyping of viral nucleic acid. To select an oral fluid collection device with optimal performance for these studies three (Orasure, Omni- SAL, Oracol) were compared. Each device collected oral fluid of sufficient quality for qualitative analysis of virus specific IgG, but DracoI was most acceptable to the subjects being tested. IgG capture ELISA (GACELISA) tests were developed for detection of rubella and anti-HBc specific IgG in oral fluid. Their sensitivity was less than that of corresponding serum ELiSAs, with sensitivity decreasing with increasing age of subjects. Whilst the performance of the rubella GACELISA was shown to be an improvement over the existing radioimmunoassay and was particularly sensitive with samples from paediatric populations, the performance of the anti-HBc GACELISA was not considered good enough for further use. The development of an RT-PCR assay targeting the El gene of rubella virus enabled the molecular epidemiology of rubella to be investigated using samples from the UK, China, Greece, and Brazil. By comparison to previously reported strains, the majority of strains were assigned to three banches of a phylogenetic tree. Those assigned to branches 1 (UK, Greece, China) and 2 (China) were not closely related to any previously reported strains. The timing of oral fluid collection and subsequent storage was critical for PCR detection. Ideally oral fluid samples should be collected within 14 days of the onset of symptoms and stored at least at -20°C prior to testing.

Imunologia das interações materno-fetais na asma: padrões de reatividade imunológica no colostro e no sangue de mães asmáticas e no sangue de cordão de seus respectivos recém-nascidos. / Immunology Interaction fetal-maternal in asthma: immunological reactive patterns in blood and colostrum from healthy and asthmatic mothers and in blood from their respective newborns.Silva, Simone Corrêa da 08 April 2008 (has links)
A Asma vem apresentando taxas de prevalência crescentes em todo o mundo. Os objetivos deste trabalho são avaliar a presença de elementos celulares e humorais indicativos em sangue e colostro de mães asmáticas e saudáveis e no sangue de cordão umbilical de seus recém-nascidos (RN). Observamos menor produção de IgG pelas mães asmáticas. Células dendríticas de mães asmáticas possuem maior expressão de CD80 e CD86. Mães asmáticas possuem mais células de memória central. Linfócitos T CD4+ de mães asmáticas produzem níveis maiores IFN-g. Células CD3+ e CD4+ de mães asmáticas produziram mais IL-13. Mães saudáveis produziram maiores quantidades de IL-10. Concluímos que mães asmáticas possuem menores níveis de IgG e IgM, o que parece aumentar dos níveis de IgE, mães asmáticas possuem mais células de memória central, linfócitos T CD4+ produzem maiores quantidades de citocinas como IL-13 e IFN-g, células dendríticas de mães asmáticas possuem maior expressão das moléculas co-estimulatórias, assim como seus RNs possuem maior expressão de CD80. Células de mães asmáticas produzem níveis menores de IL-10, o colostro de mães atópicas não possui diferenças entre os parâmetros aqui estudados. O aleitamento materno deve ser indicado para mães asmáticas e seus filhos. / Asthma has been presenting higher prevalence rates worldwide. The objective of this work is to evaluate the presence of cellular elements and humoral indicative in blood and colostrums of healthy and asthmatic mothers and in cord umbilical blood of their newborn (NB). Lower production of IgG from asthmatic mothers was observed. Dendritic cells of asthmatic mothers have higher CD80 and CD86 expression. Asthmatic mothers have more central memory cells. TCD4+ lymphocyte of asthmatic mothers produce higher levels of IFN-g. CD3+ and CD4+ cells of asthmatic mothers produce higher quantity of IL-13. Healthy mothers produce higher quantity of IL-10. We conclude that asthmatic mothers have lower levels of IgG and IgM, and this seems to raise the IgE levels, asthmatic mothers have more central memory cells, CD4+ T lymphocyte and produce higher quantities of cytokines such as Il-13 and IFN-g. Dendritic cells of asthmatic mothers have higher expression of costimulatory molecules, as well as their NBs have higher expression CD80. Cells of asthmatic mothers produce lower levels of IL-10, the colostrums of atopic mothers does not have differences in the parameters here studied. The maternal breastfeeding must be indicated for asthmatic mothers and their of spring.
