1. 16. Studies on bacterial transmission pathways in a high endemic area, with a focus on Helicobacter pylori

   Författare :Anders Janzon; Göteborgs universitet; []
   Nyckelord :H. pylori; enterotoxigenic E. coli; V. cholerae; real-time PCR; transmission pathways; gastroenteritis; mouse infection models; bacterial gene expression;

   Sammanfattning : Even though half of the world’s population is infected with Helicobacter pylori, which causes gastritis, peptic ulcer and gastric cancer, the transmission routes of these bacteria remain unknown despite extensive epidemiological studies. Enterotoxigenic Escherichia coli (ETEC) and Vibrio cholerae are two of the most common causes of acute watery diarrhea in developing countries. LÄS MER

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Escherichia coli; extended-spectrum β-lactamase; whole genome sequencing; plasmids; hybrid assembly; environment; IncI1; ST131;

   Sammanfattning : Escherichia coli is a commensal inhabitant in the gastro-intestinal tract of humans and animals but it is also the most common bacterial species causing urinary tract infection, which ranges in severity from distal cystitis to urosepsis and septic shock. During the past decades, the prevalence of antibiotic resistant E. LÄS MER

4. 18. Leishmaniasis in Sweden. Molecular, diagnostic and epidemiological studies of the parasite Leishmania in a non-endemic country

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; leishmaniasis; Parasite; Epidemiological studies; Serology; diagnostic method; Immune System; Sweden; leishmaniasis; Leishmania; immune system; chitinase; CAZy; Immune evasion; Antimicrobial peptide AMP ; Chemokine; epidemiology; Sweden; Serological assays; diagnostic method;

   Sammanfattning : This doctoral thesis consists of four separate papers, in which we; investigate epidemiological and clinical aspects of leishmaniasis in Sweden in order to increase awareness of the disease, elucidate some aspects of the interaction of the parasite and the human immune system and validate serological tools as a complement for diagnosis of leishmaniasis..

5. 19. The role of rodents in the transmission of Echinococcus multilocularis and other tapeworms in a low endemic area

   Författare :Andrea Miller; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Echinococcus multilocularis is zoonotic tapeworm in the Taeniidae family with a two part lifecycle involving a canid definitive host and a rodent intermediate host. The work of this thesis followed the first identification E. multilocularis in Sweden in 2011 in a red fox (Vulpes vulpes). LÄS MER

7. 20. Development of AIDS associated and endemic Kaposi sarcoma : HHV-8/KSHV viral load in cutaneous and oral tumor cells

   Författare :Fatemeh Pak; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Oral Kaposi s sarcoma . HHV-8 . immunohistochemistry; PCR ; lymphatic ascular endothelium;

   Sammanfattning : Kaposi's sarcoma (KS) is a highly and abnormally vascularized tumor-like lesion which usually presents as a cutaneous lesion and eventually progresses to systemic disease usually in the gastrointestinal (G1) tract, lungs, oral cavity and lymph nodes. Whether KS represents a predominantly monoclonal neoplastic cell proliferation or a hyperplastic, reactive polyclonal process is still controversial. LÄS MER
