  1. 1. KNOW YOUR ENEMY : Characterizing Pathogenic Biomaterials Using Laser Tweezers

    Författare :Tobias Dahlberg; Magnus Andersson; Krister Wiklund; Mikael Sjödahl; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Optical Tweezers; Laser Tweezers; Raman Spectroscopy; Bacterial Adhesion; Biophysics; Pili; Bacterial Spores; Endospores; Oocysts; Cryptosporidium; Optics; biology; biologi; fysik; Physics;

    Sammanfattning : Diseases caused by pathogenic agents such as bacteria and viruses result in devastating costs on personal and societal levels. However, it is not just the emergence of new diseases that is problematic. Antibiotic resistance among bacteria makes uncomplicated infections difficult and lethal. LÄS MER

  3. 2. Infection dynamics of Cryptosporidium bovis and Cryptosporidium ryanae in cattle

    Författare :Malin Åberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In order to investigate the infection dynamics of the protozoan parasites Cryptosporidium bovis and Cryptosporidium ryanae in cattle, a Swedish dairy farm known to be free of C. parvum was recruited. LÄS MER

  4. 3. Wastewater discharges and microbial variability in a surface water source

    Författare :Johan Åström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; faecal indicators; pathogens; drinking-water; microbial risk assessment; variability; rainfall; catchment; wastewater; surface water; Hazardous events;

    Sammanfattning : Planning for drinking-water safety in surface waters includes a systematic assessment of hazards in the catchment, and microbial contamination is considered a major health risk. The aim of this thesis was to identify and characterize microbial hazardous events reported for River Göta älv, Sweden. LÄS MER

  5. 4. Cryptosporidium infection in dairy cattle : prevalence, species distribution and associated management factors

    Författare :Charlotte Silverlås; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : For almost 25 years, it has been known that Cryptosporidium parasites infect Swedish calves. This thesis explores how common these parasites are at herd level and at individual level in preweaned calves, young stock and periparturient cows. Species distribution and association with diarrhoeal problems are also highlighted. LÄS MER

  7. 5. Immune evasion and dissemination of Toxoplasma gondii

    Författare :Henrik Lambert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Toxoplasma gondii is an obligate intracellular protozoan parasite which propagates in a complex life cycle where infection of Felidae family-members (Cats) results in sexual recombination whereas all other warm-blooded animals are intermediate hosts. Approximately one third of the human population is estimated to be chronically infected by this parasite. LÄS MER
