  2. 6. Genetic variability and nitrogenase activity of cyanobacterial communities associated with tropical seagrass meadows (western Indian Ocean)

    Author : Mariam Hamisi; Birgitta Bergman; Thomas Lyimo; Beatriz Díez; Lucas Stal; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; nitrogenase activity; diazotrophs; seagrass; western Indian ocean; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Tropical seagrass ecosystems are highly productive and important for sustaining marine life and associated coastal societies. In this study, the diversity and role of nitrogen-fixing cyanobacteria associated with five common seagrass genera in coastal regions of the western Indian Ocean (WIO; Tanzania) were examined, as well as the impact of anthropogenic activities.

    Author : Sofia Omar Viegas; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mozambique is one of the high burden tuberculosis (TB) and human immunodeficiency virus (HIV) countries with a prevalence of HIV infection in adults of 11.5% and an estimated TB prevalence of 559 per 100 000 population. Fifty six percent of the TB patients in Mozambique are estimated to be HIV positive. READ MORE

  6. 9. Immunity to malaria: importance of exposure and parasite polymorphism

    Author : Klara Sondén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Malaria continues to carry an intolerable burden of disease and mortality, predominantly on children in Sub-Saharan Africa. An efficacious vaccine would be a powerful tool in the combat against malaria. READ MORE

  7. 10. Exploring the metagenome of the Baltic Sea sediment

    Author : Fredrik Hårdeman; Sara Sjöling; Gunnar Sandström; Kornelia Smalla; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maringeologi; Bakterier;

    Abstract : Environmental microorganisms are fundamental to ecosystem function, acting as drivers in processes such as primary production, organic matter remineralisation, pollution remediation and global biogeochemical cycling. However, the study of the bacterial communities requires the application of advanced culture-independent methods considering that only a small fraction of the community is otherwise accessed.
