  2. 1. Dynamics of Coinfection : Complexity and Implications

    Author : Samia Ghersheen; Vladimir Kozlov; Uno Wennergren; Vladimir Tkachev; Åke Brännström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. READ MORE

  4. 2. HIV-2 genetic evolution and viral dynamics

    Author : Eleonor Brandin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HIV-2; antiretroviral treatment; resistance; pathogenesis; co-receptor; neutralization; viral dynamics;

    Abstract : HIV-2 is less pathogenic and less transmissible compared to HIV-1. This is believed to be due to the lower viral load that is seen in HIV-2 infected patients. However, why this lower viral load is seen is not known. In this thesis we have investigated different aspects of HIV-2 in order to understand the pathogenesis of HIV-2 better. READ MORE

  5. 3. Imported infections’ importance : global change driving Dengue dynamics

    Author : Mikkel B. Quam; Joacim Rocklöv; Annelies Wilder-Smith; Eduardo Massad; Dave D. Chadee; Umeå universitet; []

    Abstract : Background Dengue is a significant problem of international health concern. According to the World Health Organization in 2012, globally, dengue is “the most important mosquito borne viral disease” with incidence 30 higher than it had been 50 years ago. READ MORE

  6. 4. Epidemiology of viral respiratory infections with focus on in-hospital influenza transmission

    Author : Martina Sansone; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; influenza; rhinovirus; infection-control; hospital outbreak; nosocomial; phylogeny; polymerase chain reaction; viral transmission; whole-genome sequencing; system dynamics;

    Abstract : Human Rhinoviruses (HRV) and influenza viruses are respiratory pathogens which represent a major global disease burden. Healthcare-associated infections (HCAI) are increasingly recognized as a public health concern, but limited data has been published on the characteristics and epidemiology of HCAI caused by respiratory viruses.

  7. 5. Viral Loop Dynamics in Temperate and Polar Freshwaters

    Author : Christin Säwström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; akvatisk ekologi; aquatic ecology; marine biology; Hydrobiology; temperate; polar; freshwaters; nutrient limitation; bacterial mortality; lysogeny; dissolved organic carbon; humic; Arctic; Antarctic; Bacteria; Virus; limnology; Marinbiologi; limnologi;

    Abstract : All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. READ MORE
