Webdosing approach to the treatment of drug resistant cancer could therefore be the use of a second drug that selectively targets the acquired vulnerability of the drug resistant cells (Fig. 2). In this model, the drug-resistant cells are actively killed by the second drug rather than being only at a disadvantage, as is the case in the ... Webantibiotic resistance, loss of susceptibility of bacteria to the killing (bacteriocidal) or growth-inhibiting (bacteriostatic) properties of an antibiotic agent. When a resistant strain of bacteria is the dominant strain in an infection, the infection may be untreatable and life-threatening. Examples of bacteria that are resistant to antibiotics include methicillin …
