    Abstract : 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. READ MORE

    Abstract : Millions of years of evolution have resulted in an immense number of different proteins, which participate in virtually every process within cells and thus are of utmost importance for allknown forms of life. In addition, there are several examples of natural proteins which have found use in applications outside their natural environment, such as the use of enzymes infood industry and washing powders or the use of antibodies in diagnostic, bioseparation or therapeutic applications.

    Abstract : Antibiotic resistance is an escalating problem, not only due to less desirable treatment options and outcome, but also due to the economic burden to health care caused by resistant pathogens. Since the process of developing new antibiotics is slow, we need to carefully consider the usage of the antibiotics still available. READ MORE
