  1. 1. 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

  3. 2. 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

  4. 3. Microbial Risks in Surface Water Sources

    Författare :Johan Åström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface water; Bifidobacteria; Microbial source tracking; Cryptosporidium.; QMRA; Flow-weighted sampling; Pathogens; Bacteroidales; Stochastic modelling; qPCR;

    Sammanfattning : Microbial risks need to be properly handled for the provision of healthy drinking water. The mitigation of pathogens in the water source lowers the risk for infection associated with nominal and suboptimal drinking water treatment. 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. Gastrointestinal parasites in pigs : prevalence, risk factors and control

    Författare :Emelie Pettersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Gastrointestinal parasites are common in pigs worldwide, and in all production types. Clinical disease is rare and mainly associated with heavy nematode infections, or piglets infected with the coccidia Cystoisospora suis. Subclinical infections are more common and may result in reduced growth and poor feed utilisation. LÄS MER
