Content of research

The application of molecular biology techniques in bacteriology is almost endless and clears the way for insight into the genetic background of the antimicrobial resistance and other properties of bacterial pathogens.

Most our research is based on understanding, at molecular, cellular and environmental levels, processes including selection, co-selection, the spread and maintenance of antimicrobial resistance and the flow of emerging resistance genes between commensals and pathogens (host and clone specificity, plasmid characterization, and association among plasmids and resistance genes).  Other specific research goals include: (i) to identify the genetic background and epidemiology of resistant clones in food animals, companion animals and wild animals - especially migratory birds; (ii) to analyse the transfer of antibiotic resistant strains from animals to humans; (iii) to identify ways to eliminate resistant bacteria from animal populations and environments; (iv) to investigate the antimicrobial efficacy of new potential chemotherapeutics and natural products.

The biology of vectors and vector-borne diseases is another field of the RG. Since the distribution and spreading of numerous species of vectors acquired a new dynamic during last two decades, the discovery and exact defining of ecological and climatic variables influencing these current changeovers will help us formulate the most imperilled areas in respect to specific vector borne diseases. We concentrate on the study of the distribution, spread, and risk levels of selected tick/vector-borne diseases.
