    Sammanfattning : I investigated the bacterial utilization of terrestrially derived dissolved organic nitrogen (DON) in aquatic ecosystems, and assessed the potential role of river-born DON in marine eutrophication. To determine the bioavailability of DON, I developed a bioassay employing N-limited bacterial regrowth cultures, which were calibrated with additions of inorganic nitrogen. LÄS MER

    Sammanfattning : Human cytomegalovirus (HCMV) is a herpesvirus. Following a primary infection, HCMV persists in the body in a latent form and most adults are virus carriers. Infection and reactivation of HCMV occur in inummocompromised patients causing severe disease and appear to be the result of inflammatory processes. LÄS MER
