Novel therapeutic priciples to overcome resistance to current antimicrobials. Innovative approaches to exploit knowledge of host/pathogen interactions and microbial and host genome for the development of new anti-bacterial and/or antifungal treatment and/or prophilaxis against micro-organisms resistant to existing antimicrobials.
2. Host recognition of pathogenic microorganisms.
Molecular mechanism of recognition of pathogenic microbes, microbial strategies to evade detection by the host, identification of potential targets for therapeutic intervention, potential for development of novel targets or therapies to boost immune response or prevent excessive stimulation.

3. Cytokines as adjuvants and bioassays for immune responseDevelopment of alternative strategies to manage infectious diseases in animals by development and application of new vaccines, based on alternative adjuvants providing long-term and safe protection, without side-effects. Use of innovative approaches exploiting knowledge on cytokines to study the immune response during vaccination. The development of use of different cytokines as vaccine as well as probiotics adjuvants is encouraged.Development of different types of biological assays for interferons based on: antiinvasive, immunomodulatory, antiproliferative, antitumor activity.
Particularly encouraged is the development of different new cell systems specifically sensitive to such kind of biological activities in comparison to ELISA.

6. Development of new diagnostical tools for autoimmune diseases
Microbial antigenes have the potential to initiate autoreactivity through molecular mimicry, polyclonal activation, or the release of previously sequestered antigens.
Development of innovative approaches, exploiting knowledge of different DC subsets in peripheral blood and development of in vitro system is proposed. Innovative approaches, exploiting knowledge of peripheral B-lymphocyte subpopulations in infections with such organisms and in patients with autoimmune diseases (SLE). Development of diagnostically valuable tools for monitoring progress of disease in patients with SLE.
