To increase the knowledge of the interaction between host and microbes

To apply this knowledge to the maintenance of health and the prevention and treatment of diseases

OBJECTIVES OF MICMANOBJECTIVES OF MICMAN

• Researcher training and exchange • Multidisciplinary networks• Internationality

SHARED ACTIVITIES ( + )SHARED ACTIVITIES ( + )

• programme memorandum: general description of the aims and the themes

• call for applications

• evaluation of applications

• proposal of decisions

• final scientific evaluation (in 2006)

• coordination: programme activities

- Funding agencies support groups on their own country only - Research reports according to slightly modified practicies

Development and application of modern molecular biology methods

Host-microbe interactionsin the development and course of diseases

Molecular biology of infections

e.g.,• Host-pathogen interaction of Streptococcus pyogenes (bacteriological, immunological and genetic studies)

• Immune evasion mechanisms and molecules of microbial pathogens (Borreliae, Streptococci

Resident microbiota

Development, composition and health effects under the influence of • host itself and• environmental factors (pathogenic and probiotic bacteria)

e.g., • Long-term impact of antimicrobial treatment for

the microbial flora of the gastrointestinal tract

• The role of probiotics in the development of the mucosal immune system in infancy

Species studied

• Borrelia • Chlamydia pneumoniae • Cyanobacteria• Echinococcus granulosus • Escherichia coli• Helicobacter pylori• Lactobacillus • Salmonella• Staphylococcus aureus• Streptococcus • Yersinia

MICMAN and Era-Net

• MICMAN will end 12/2005 ....however

• Continuation as a “virtual programme”

• We are ready and willing to collaborate regarding organizations of workshops, seminars,

post-graduate courses, etc.

• Proposal for a graduate school (2006-2009) under preparation

Annual Seminar of MICMAN: February 16-17, 2005 Helsinki, Finland (www.aka.fi/micman >Events)

• Allocation of funding to the transnational calls of Era-Net? (Academy of Finland, SSF?)

Host-microbe interactions in the development and course of diseases

MICMAN PROJECTSMICMAN PROJECTS

1. Reactivation and immune evasion of Borrelia infection - Aim: interactions of Borrelia spirochetes and the host during infection (e.g. production of gene expression data in interaction with host)

2. Pathogenesis of reactive arthritis - Aim: mechanisms and molecules behind the incomplete eliminarion of bacteria causing reactive arthitis (Salmonella/Yersinia).

3. Microbes and allergy: From population observations to animal models - Aim: relative role of genes vs. environment in atopic diseases (H.pylori)

4. Microbial factors and host resposes discriminating commensals from pathogens - Aim: bacterial factors and mechanisms that cause the host to regulate its reactions to asymptomatic colonisers and pathogenic bacteria (Salmonella, Streptococcus, Lactobacillus)

5. A paradox of a microbe and man - what makes Staphylococcus aureus a pathogen? - Aim: to develop a system for the virulence gene expression studies in S.a.

6. Genetic susceptibility to streptococcal infections - Aim: to study e.g. molecular properties of various streptococcal strains

MICMAN PROJECTSMICMAN PROJECTSHost-microbe interactions in the development and course of diseases

MICMAN PROJECTSMICMAN PROJECTS

7. Microbial resistance to innate immunity - Aim: immune evasion mechanisms of microbes; deficiencies that predispose to infections

8. Host-microbe interaction in acute and persistent Chlamydia pneumoniae infection - Aim: molecular mechanisms by which C.p. contributes to the pathogenesis of acute and persistent infections

9. Microbial pathogenesis of cardiovascular disease - Aim: ethiological role of Chlamydia pneumoniae and other microbes and the host inflammatory response

Host-microbe interactions in the development and course of diseases

MICMAN PROJECTSMICMAN PROJECTS

10.Bacterial-epithelial cross-talk and the establishment of the mucosal immune system - Aim: role of bacterial-epithelial cell interactions for intestinal leukocyte populations 11. Microbial ecology of man in health and disease: Emergence, spread and persistence of antibiotic resistance in the normal microflora - Aim: e.g. to develop new molecular methods for analyses of normalflora 12.Host-microbe crosstalk in infancy: creating a balance between the internal and external environments - Aim: effects of probiotics on infants

13.DNA microarrays for studying interactions of probiotic, pathogenic and normal gut microbiota bacteria with human intestinal epithelial cells - Aim: gene expression patterns elicited in host intestinal cells by

pathogenic, probiotic and normal intestainal bacteria

Resident microflora

MICMAN PROJECTSMICMAN PROJECTS

14. Infectious origins of the human genome. Human endogenous retroviruses in health and disease - Aim: Development of bioinformatics

15. Cyanobacteria and adjacent microbes: causes of acute human intoxications and indicators of water quality - Aim: acute intoxications associated with cyanobacteria; causative agents and mechanisms
