Although antibiotic resistance is a global issue, the exact nature of the problem shows geographical variation. Hence, the particular problems facing Europe differ from those in other geographical regions. The results obtained during the ANTIRESDEV project will enable governments and healthcare providers to formulate strategies to combat the growing threat posed by antibiotic-resistant bacteria in Europe. The new microarrays developed during the project will be very useful in diagnostic laboratories to rapidly determine which antibiotics would be ineffective against a disease-causing organism in a particular individual. Additionally, they will be useful in surveillance studies of antibiotic resistance. The project results will enable a better understanding of the molecular mechanisms underlying the spread of mobile genetic elements and this will help in the development of means of preventing or reducing horizontal gene transfer and the dissemination of resistance.
