| ecological comparison of the risks of mother-to-child transmission and clinical manifestations of congenital toxoplasmosis according to prenatal treatment protocol. | we compared the relative risks of mother-to-child transmission of toxoplasma gondii and clinical manifestations due to congenital toxoplasmosis associated with intensive prenatal treatment in lyon and austria, short term treatment in 51% of dutch women, and no treatment in danish women. for each cohort, relative risks were standardized for gestation at seroconversion. in total, 856 mother-child pairs were studied: 549 in lyon, 133 in austria, 123 in denmark and 51 in the netherlands. the relativ ... | 2001 | 11561963 |
| effect of prenatal treatment on mother to child transmission of toxoplasma gondii: retrospective cohort study of 554 mother-child pairs in lyon, france. | the aim of prenatal serological screening for toxoplasmosis is to identify and treat maternal infection as soon as possible in order to prevent transmission of the parasite to the fetus. however, despite widespread provision of prenatal toxoplasma screening across europe, the effectiveness of prenatal treatment is uncertain. the study aimed to determine the effect of the timing and type of prenatal treatment on mother to child transmission of toxoplasma gondii. | 2001 | 11821334 |
| spatial distribution of soil contamination by toxoplasma gondii in relation to cat defecation behaviour in an urban area. | in urban areas, there may be a high local risk of zoonosis due to high densities of stray cat populations. in this study, soil contamination by oocysts of toxoplasma gondii was searched for, and its spatial distribution was analysed in relation to defecation behaviour of cats living in a high-density population present in one area of lyon (france). sixteen defecation sites were first identified. cats were then repeatedly fed with marked food and the marked faeces were searched for in the defecat ... | 2008 | 18325523 |
| discrepancies between a new highly sensitive toxoplasma gondii elisa assay and other reagents: interest of toxo igg western blot. | immunodiagnostic assays are commonly used to screen for maternal toxoplasmic seroconversion during pregnancy. the introduction to the market of a new highly sensitive igg assay, the elecsys toxo igg test, has resulted in discrepancy issues with other immunoassays because of a lack of standardisation. western blot appears to be a good alternative gold standard to the dye test, as the latter is not routinely available. for the present prospective study, we compared the analytical performances of t ... | 2011 | 21484254 |
