Once the pathogen is identified, AFC is also used in the therapeutic assessment of antibiotics on&nbsp.the clinical course of infection by examining patient cells by AFC post-treatment. In this regard, AFC is an important biomedical tool in the assessment of parameters of clinical sensitivity and resistance of specific bacterial strains to specific therapeutic regimens (Davey & Kell, 1996). In addition, AFC can be used to measure the cellular DNA and protein concentration and the activity of specific&nbsp.enzymes (Roederer 2001).
