Antibiotic susceptibility testing (AST) specifies effective antibiotic dosage and formulates a profile of empirical therapy for the proper management of an individual patient’s health against deadly infections. Therefore, rapid diagnostic plays a pivotal role in the treatment of bacterial infection. In this article, the authors review the socio-economic burden and emergence of antibiotic resistance. An overview of the phenotypic, genotypic, and emerging techniques for AST has been provided and discussed, highlighting the advantages and limitations of each. The historical perspective on conventional methods that have paved the way for modern AST like disk diffusion, Epsilometer test (Etest), and microdilution, is presented. Several emerging methods, such as microfluidic-based optical and electrochemical AST have been critically evaluated. Finally, the challenges related with AST and its outlook in the future are presented.

Diabetic foot complications are the most common occurring problems throughout the globe, resulting in devastating economic crises for the patients, families and society. Diabetic foot ulcers (DFUs) have a neuropathic origin with a progressive prevalence rate in developing countries compared with developed countries among diabetes mellitus patients. Diabetic patients that are of greatest risk of ulcers may easily be diagnosed with foot examination. Economic burden may be carefully examined. The budget costing must include both the clinical and social impact of the patients.
