Abstract
Introduction
Antibiotic drug resistance is a perpetual and growing source of medical need; however, diagnostics that can identify drug-resistant pathogens are limited in number. As bacteria develop resistance to more agents and classes of antibiotics, the need for rapid diagnostics that can provide diagnostic accuracy and help in patient management (i.e., by helping physicians administer appropriate therapy quickly) will grow urgent. Diagnostics companies should take heed of the significant market opportunity thus presented.

Antibiotic drug resistance continues to plague the community and hospital settings. Which setting is more lucrative for the uptake of diagnostics? What features are needed to penetrate these settings? Currently, most diagnostics identifying drug-resistant pathogens are designed to detect methicillin-resistant Staphylococcus aureus (MRSA). Which pathogens represent future opportunities? Many diagnostics (e.g., phenotypic tests, molecular tests) are now available to detect pathogens and determine antibiotic susceptibility. Where do future opportunities lie? What challenges must be overcome? With the availability of better diagnostics for identification of resistant pathogens, treatment practices in the community and the hospital are likely to be impacted. How will the widespread use of diagnostics affect drug development and use of current drugs? Will it increase or decrease use of drugs such as daptomycin, linezolid, and tigecycline?
