2. 1. Streptococci and Platelets - A Study of Host-Pathogen Interaction Dynamics

   Author : Lisbeth Svensson; Infektionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; host-pathogen interactions; bacterial entrapment; disaggregation; aggregation; platelet activation; Streptococci;

   Abstract : Invasive infections remains one of the leading causes of death due to infections over the world, and efficient treatment remains elusive. One of the major causes of sepsis and other invasive infections is pathogenic streptococci that cause a wide range of clinical manifestations in humans. READ MORE

4. 2. Host-Pathogen Responses during Giardia infections

   Author : Emma Ringqvist; Staffan Svärd; Patricia Johnson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Giardia; parasite infection; host-parasite releationship; immune activation; virulence factor; immune evasion; Cell and molecular biology; Cell- och molekylärbiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

   Abstract : Giardia lamblia is a eukaryotic parasite of the upper small intestine of humans and animals. The infecting trophozoite cells do not invade the epithelium lining of the intestine, but attach to the brush border surface in the intestinal lumen. The giardiasis disease in humans is highly variable. READ MORE

5. 3. MHC polymorphism and host-pathogen interactions: The case of Borrelia in its reservoir host, the bank vole Myodes glareolus

   Author : Kristin Scherman; MEMEG; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Host-pathogen interaction; Negative frequency dependent selection; Myodes glareolus; Borrelia;

   Abstract : The major histocompatibility complex (MHC) class IIB genes exhibit extensive allelic polymorphism, most likely maintained by pathogen-mediated balancing selection (PMBS). PMBS may operate in the form of heterozygote advantage (HA), and/or through the interaction of pathogens and specific MHC alleles via fluctuating selection (FS) or negative frequency-dependent selection (NFDS).

6. 4. Mechanisms of microbial-host interaction during asymptomatic bacteriuria

   Author : Jenny Grönberg Hernandez; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asymptomatic bacteriuria; Urinary tract infection; Escherichia coli 83972; IRF3; TLR4; Evolution; host response; promoter polymorphisms; transcription; P fimbriae; Type 1 fimbriae;

   Abstract : Urinary tract infections (UTIs) present an interesting and relevant model for studying microbial adaptation. After establishing significant numbers, the bacteria either cause severe disease, or an asymptomatic carrier state resembling the normal flora at other mucosal sites. READ MORE

7. 5. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms

   Author : Gabriela Wassing; Ann-Beth Jonsson; Elena Vikström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Lactobacillus; host responses; EGR1; antimicrobial peptides; hBD2; A20; biofilm; molekylär biovetenskap; Molecular Bioscience;

   Abstract : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. READ MORE
