    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Kemiteknik och kemisk teknologi; Chemical technology and engineering; real-time PCR; YPCE medium; Enrichment PCR; DNA polymerases; PCR inhibitors; pre-PCR processing; Salmonella; Diagnostic PCR; Yersinia enterocolitica; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : This thesis deals with the methodological advances of diagnostic PCR including reliability of PCR and pre-PCR processing of food and feed samples. Diagnostic PCR has been greatly improved by the introduction of the second generation of PCR, so-called real-time PCR. LÄS MER

  3. 2. Salmonella in pigs : infection dynamics of different serotypes

    Författare :Julia Österberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In recent years several incidents of feed-borne spread of Salmonella spp. have been documented in Swedish pig herds, including serotypes previously not associated with pigs. In this thesis two feed-associated serotypes (S Cubana and S Yoruba) were compared with two serotypes commonly detected in pigs (S Typhimurium and S Derby). LÄS MER

  4. 3. Human salmonellosis : impact of travel and trade from a Swedish perspective

    Författare :Birgitta De Jong Skierus; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Salmonella; salmonellosis; reptile-associated salmonellosis; travel-associated salmonellosis; S. Enteritidis; European salmonella incidence; serotype; serovar; sewage treatment plants; antibiotic resistant; pre-travel advice.;

    Sammanfattning : Background: Salmonellosis is one of the most important gastrointestinal infections in humans. The vast majority of Swedish Salmonella cases have acquired the disease abroad, reflecting both a large number of Swedish travellers and a very favourable domestic Salmonella situation compared to other countries, mainly due to various control programs implemented in the animal food production and import regulations (e.

  5. 4. Characterization of Shigella dysenteriae type 1 hybrid vaccine candidates

    Författare :Inger Fält; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Shigellae is endemic in many developing countries in the world and a major cause of childhood diarrheal morbidity and mortality. Infections caused by Shigella dysenteriae type 1 are particularly severe. LÄS MER

  7. 5. Immune responses to lipopolysaccharide in relation to allergic disease : a TLR4 gene polymorphism and endotoxin exposure

    Författare :Anna Lundberg; Malin Fagerås Böttcher; Outi Vaarala; Marita Troye-Blomberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background: Allergic diseases have increased during the last decades, particularly in affluent countries, possibly due to a reduced and/or altered microbial exposure during infancy. Activation of the immune system by microbes early in life is probably required for accurate maturation of the immune system and tolerance development. LÄS MER
