A strain in the Continua presented of the drug; a resistant strain in the sensitive strain in the continued presence of the drug; A resistant strain in the absence of the drug The figure at right shows effectiveness of two different antibiotics against a pathogen isolated from a patient' spinal fluid. Explain why a clinician might choose to treat the patient with drug A? drug B may not penetrate to the central nervous system drug B might be known to have a toxic side effect on the patient (patient allergy) Drug A levels might be higher and maintained longer than drug B. all of the above c) A and B only A War one around an antimicrobial disk on a plate brine used tor a Kirby-Hauler test indicate, where bacteria are not able to grow. complete susceptibility of the bacteria to the antimicrobial. of the bacteria to the antimicrobial. a negative result.
