New Approaches for Imaging Bacteria

Abstract

Bacterial infections are a major threat to human health. Rapid and accurate diagnosis of bacterial infections is essential for early interventions and rational use of antibiotic treatments. However, antibiotics are often initiated empirically while diagnostic tests are being performed. Moreover, traditional diagnostic tools, namely microscopy, microbiology and molecular techniques, are dependent upon sampling suspected sites of infection, and then performing tests. This approach is often invasive, labor intensive, time consuming, and subject to the uncertainties of incorrect sampling and contamination. There are currently no imaging approaches for the specific detection of bacterial infections. Therefore, there is a need for new noninvasive approaches to detect, localize and monitor bacterial infections with high sensitivity and specificity.
