  1. 1. Viruses on the wing: evolution and dynamics of influenza A virus in the Mallard reservoir

    Author : Michelle Wille; Jonas Waldenström; Timm Harder; Linnéuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Co-infections; Ecology; Epidemiology; Evolution; Host-Parasite Interactions; Immunity; Influenza A Virus; Mallard; Phylogeny; Virology; Waterfowl; Wild Birds; Wildlife Disease; Zoonotisk ekologi; Zoonotic Ecology;

    Abstract : This thesis explores the evolution of avian influenza A viruses (IAV), as well as host-pathogen interactions between these viruses and their main reservoir host, the Mallard (Anas platyrhynchos). IAV is a genetically diverse, multi-host virus and wild birds, particularly dabbling ducks, are the natural reservoir. READ MORE

  2. 2. Streptococcus equi subsp. equi and Streptococcus equi subsp. zooepidemicus : upper respiratory disease in horses and zoonotic transmission to humans

    Author : Susanne Lindahl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : The bacterium Streptococcus equi subsp. equi (S. equi) is the causative agent of the highly contagious upper respiratory disease "strangles" in horses. The ancestor of S. READ MORE

  3. 3. Birds and Borrelia

    Author : Björn Olsen; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Ixodes ticks; Birds; Epidemiology; Zoonotisk ekologi; Zoonotic Ecology; Virology; Virologi; Mikrobiologi; Microbiology;

    Abstract : The Lyme disease causing spirochaete Borrelia burgdorferi sensu lato is transmitted by ticks within the genus Ixodes. These ticks are liberal host seekers and parasitise mammals, birds and reptiles.Prior to this study, the distribution of I. ricinus ticks and Lyme disease was thought to be restricted to the southern half of Sweden.

  4. 4. The zoonotic pathogen Borrelia afzelii in its natural hosts : Bacterial dissemination and immuno-transcriptomics

    Author : Xiuqin Zhong; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Borrelia afzelii; natural hosts; bacterial load; immune response; RNA-seq;

    Abstract : Most pathogens can infect a number of different host species, but host species often differ considerably in susceptibility to a given pathogen. In the case of zoonotic pathogens, natural hosts typically present little or no disease symptoms, while humans and other “spill-over” hosts often present severe symptoms. READ MORE

  5. 5. Studies on verotoxigenic Escherichia coli O157 in Swedish cattle : from sampling to disease spread modelling

    Author : Stefan Widgren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : Verotoxigenic Escherichia coli O157:H7 (VTEC O157) is an important zoonotic pathogen capable of causing infections in humans, sometimes with severe symptoms such as hemorrhagic colitis and hemolytic uremic syndrome (HUS). Cattle are considered to be the main reservoir of the bacterium. READ MORE
